Since yesterday I've had this error when I try to import packages on anaconda :
ImportError: Missing required dependencies ['numpy']
I have tried un-installing Anaconda and Python, switching to Python 2.7 but nothing works it's still the same error, here is the code I get :
Any help is really appreciated thanks !
I had this same issue immediately after upgrading pandas to 0.19.2. I fixed it with the following install/uninstall sequence from the windows cmd line:
pip uninstall pandas -y
pip uninstall numpy -y
pip install pandas
pip install numpy
This also broke my matplotlib install so I uninstalled/installed that as well.
Very odd behavior for a seemingly routine upgrade.
What happens if you try to import numpy?
Have you tried'
pip install --upgrade numpy
pip install --upgrade pandas
I had to install this other package:
sudo apt-get install libatlas-base-dev
Seems like it is a dependency for numpy but the pip or apt-get don't install it automatically for whatever reason.
I had this problem with last version of numpy 1.16.x
Problem resolved with
python3 -m pip uninstall numpy
python3 -m pip install numpy==1.14.0
Did you install miniconda and pandas without dependencies?
Try installing numpy first with conda install numpy or pip install numpy.
If you're on Windows you can get pre-compiled versions of most libraries that require compilation from here.
On Windows 10 Anaconda3-5.3.0-Windows-x86_64 I had the Missing required dependencies ['numpy'] error when running scripts as so, %HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe pandas_script_foo.py.
In my case the error was caused by missing Anaconda package PATH definitions when running Anaconda python.exe in a windows cmd.exe session. The numpy package is not missing. It just can't be found on the PATH.
The Anaconda installation includes windows shortcuts that give examples of configuring the PATH per script run. See the shortcuts in the %HOMEPATH%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit) directory for examples.
See the %HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py script to see how Anaconda configures PATH.
Below is an example windows BAT file that calls cwp.py to setup PATH, and then run a python script. Its a copy of the commands the Anaconda jupyter-lab shortcut executes.
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\cwp.py ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3 ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\python.exe ^
%HOMEPATH%\AppData\Local\Continuum\anaconda3\Scripts\jupyter-lab-script.py
If you need to execute python scripts on Anaconda with the conveniance of running a BAT file, the above BAT file example should do the trick.
The data manipulation capabilities of pandas are built on top of the numpy library. In a way, numpy is a dependency of the pandas library. If you want to use pandas, you have to make sure you also have numpy. When you install pandas using pip, it automatically installs numpy. If it doesn't, try the following
pip install -U numpy pandas
For conda
conda install numpy pandas
I also faced the same issue. It happened to me after I upgraded my numpy library.
It was resolved in my case by upgrading my pandas library as well after upgrading my numpy library using the below command:
pip install --upgrade pandas
Try:
sudo apt-get install libatlas-base-dev
It should work now.
Else, try uninstall and reinstall numpy and pandas.
I had the same issue. It was because I had multiple versions of numpy installed. Remove all versions by repeatedly using:
pip uninstall numpy
Then re-install it with the command:
pip install numpy
First, try to import numpy on it's own, like so:
import numpy as np
I got this message:
ImportError: Something is wrong with the numpy installation. While importing
we detected an older version of numpy in
['/home/michael/.local/lib/python3.6/site-packages/numpy']. One method of
fixing this is to repeatedly uninstall numpy until none is found, then
reinstall this version.
So do what it says, keep uninstalling numpy until there is none, and then reinstall.
This worked for me.
I had the same issue while using Microsoft Visual Code with Python 3.7.3 64-bit('base':conda)as my python interpreter. Before running any code type the following three commands:
C:/ProgramData/Anaconda3/Scripts/activate #activate conda Scripts directory
conda activate base #activate conda
& C:/ProgramData/Anaconda3/python.exe #to run python
I have same problem.
I have got two version of numpy 1.16.6 and 1.15.4, fresh installed pandas did not work correctly.
I fixed it by uninstalling all versions of numpy and pandas and install the last versions.
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.16.6:
Successfully uninstalled numpy-1.16.6
Uninstalling pandas-0.24.2:
Successfully uninstalled pandas-0.24.2
$ pip uninstall numpy pandas -y
Uninstalling numpy-1.15.4:
Successfully uninstalled numpy-1.15.4
Cannot uninstall requirement pandas, not installed
$ pip uninstall numpy pandas -y
Cannot uninstall requirement numpy, not installed
$ pip install numpy pandas
I had the same issue with anaconda package, it got updated.
anaconda {4.3.1 -> custom} ## I am not sure if this was the issue
Hit below command to know
conda list --revisions
what i did is just uninstall pandas with conda and re-install it
conda install pandas
Some new libs may also get installed with it.
It worked for me hope will do the same for you.
Uninstall all pip packages that you're having problems with. Manually remove all site-packages files. If you're using MacPorts, sudo port clean .
Then try reinstalling. Sometimes, there are files that should have been removed, but weren't if the installation was abruptly interrupted or something.
There could be an issue with conflicting versions of the package(s), as well as potentially issues with Pathing. Are you sure you've set the correct Path for your binaries? (/opt/local/bin, /anaconda2/bin, etc.)
Another issue could be some PYTHONPATH that's explicitly looking in the wrong place for the file.
I had a same issue recently with Anaconda with Python 3.7.
I solved this problem by downgrading python version to 3.6:
conda install python=3.6
and then by updating all the packages:
conda update --all
pandas is built on top of numpy so you need to have numpy to use the data manipulation feature, so install numpy first.
pip install numpy
This worked in my anaconda environment, but I do not know why conda does not work. For some reason conda uninstall was not sufficient. This only worked with conda remove.
conda remove pandas
conda remove numpy
conda install pip
pip install pandas
*With help from this answer
This raises the following import warning in python 3.6 and 3.7:
ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__
If you with to ignore this warning (and maybe other ImportWarnings), add the following to your script before importing pandas:
import warnings
warnings.filterwarnings('ignore', category=ImportWarning, module='_bootstrap.py')
In my case even though I was using the above options of uninstall and installing using pip the code was still giving me same errors.
Finally, I created a vritual environment and Installed numpy and pandas using pip in my virtual env. Now the code is running.
Steps: for Anaconda3 - Please change according to your installation type:
[if you dont have virtual env package installed]
$ pip install virtualenv
[from command prompt go to the directory by c:\anadonda3\scripts
[write the following command to use virtual env to create a virtual env for you in your desired location]
$virtualenv c:\anaconda3\envs\my_virtual_env
[once created you will have to activate your virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts activate
[now pip install numpy and pandas and other required packages using pip]
[once installations are done exit from the virtual env]
$c:\anaconda3\envs\my_virtual_env\scripts deactivate
now use the python.exe inside your virtual env folder to run the script and it will run even with python 3.7.
I am using Win10 and Conda, and this issue just append to me when upgrading python 3.7.2-h8c8aaf0_0 --> 3.7.2-h8c8aaf0_2.
I solved it by return to the previous version with
conda install python=3.7.2=h8c8aaf0_0
If you're running your program on PyCharm on Windows, there is a known bug, because PyCharm simply doesn't add env-related paths to PATH.
The issue is fixed in the 2019.1 Early Access Preview (EAP) build.
For me installing the EAP fixed the issue.
nothing worked for me ... except when I found this
I suspect that you have a local file called unittest.py that is getting imported instead of the standard module.
I was trying to upgrade my anaconda 2 with anaconda 3. I tried installing Anaconda3-2018.12-Windows-x86 and Anaconda3-2019.03-Windows-x86_64 on my Windows 10 machine and failed with this error. For me, using Anaconda3-4.4.0-Windows-x86_64 for anaconda 3 worked the trick after trying everything listed in answers here.
I fixed this using Anaconda by going to Environments > base(root), searching for numpy in the installed modules and clicking the tickbox alongside it and choosing > Mark for specific version installation > 1.14.0 (as suggested by another user on this thread). Then clicking Apply. Once it downgraded numpy I stopped getting errors when running py files on the command line.
Throughout this saga, I was still able to use https://pypi.org/project/auto-py-to-exe/ even when I was getting the numpy errors on the command line, but it was a hassle to create an exe every time I wanted to test a change. It's all sorted now. I guess there was a problem with numpy 1.16.4.
Anyway, I hope this helps someone who's using Anaconda as well.
The following worked for me.
Deleted the folders for numpy and pandas together with their contents completely from the site-packages folder. Check depending on whether you are using python2 or python3. Check the exact path as per your machine.
N.B handle with care "rm -rf" command. If you are not sure of what you are doing, please do it manually using any file explorer of your choice!!
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/pandas*
rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/numpy*
Then i installed clean packages for pandas and numpy as usual with
pip install numpy
pip install pandas
I've got the same error recently. Before applying uninstall or install tools, try to update your Jupyter.
How? Go to 'Environments' and type on the Search Packages box 'pandas'. Afterwards, check the version (if that column shows a blue number with a diagonal arrow, it means that your pandas is out of date). Click on 'pandas' and a option will pop up (choose 'Apply' and wait for a couple of minutes to update the package). And then, make a quick test on any notebook to make sure that your Jupyter is running smoothly.
For those who couldn't solve with the above answers:
Ensure that you are running python3 with
$ python version
If not, install python3.
Then change default python to python3 with
$ alias python=python3
Next, close your jupyter lab/notebook environment and re-launch it with default python being python3.
build_exe_options = {"packages": ["os",'pandas','numpy']}
It works.
you are running python 3.7
create environment for python 3.6
python3.6 filename.py

After installing pypfopt and u-numpy, dataframe.info() command shows this error.
TypeError: Cannot interpret '<attribute 'dtype' of 'numpy.generic' objects>' as a data type
I happened to mix my versions and I encountered the problem today. I managed to fix it.
Both codes in jupyter gave me an error: TypeError: Cannot interpret '<attribute 'dtype' of 'numpy.generic' objects>' as a data type
df.info()
df.categorical_column_name.value_counts().plot.bar()
I got the error: TypeError: Cannot interpret '<attribute 'dtype' of 'numpy.generic' objects>' as a data type
This is how i fixed it
Inside jupyter:
Check numpy version:
import numpy as np
print(np.__version__)
To upgrade:
!pip3 install numpy --upgrade
Inside Command line check numpy version:
python
import numpy
print(numpy.__version__)
if versions are not the same choose whether to upgrade/downgrade:
To upgrade:
$pip install numpy --upgrade
To downgrade just specify the version
If you have python environment installed:
Go to the right folder:
Check the installed version:
$pipenv --version
To verify if you have a pip environment installed for that folder:
On your terminal Go to the folder and type:
$pipenv --version
If there is a pipenv it will show the version and if there is none it won't.
check numpy version
$python
>>> import numpy
#prints the version
>>> print(numpy__version__)
To upgrade the version:
>>>exit()
#To install the latest version don't specify the version
$pipenv install numpy
#if you want to downgrade specify the version
$pipenv install numpy=version_type
Do the same for pandas. Note that with pandas if your pandas environment is 1.2.3 on the jupyter notebook upgrade with !pip install pandas==1.2.3 or just !pip install pandas --upgrade --user.
Note that if the commands are giving you an error always include --user at the end of the command.
To create a new environment using miniconda and install updated packages follow the link [https://pandas.pydata.org/pandas-docs/stable/getting_started/install.html][1]
Run the following commands from a terminal window:
conda create -n name_of_my_env python
This will create a minimal environment with only Python installed in it. To put your self inside this environment run:
source activate name_of_my_env
On Windows the command is:
2. activate name_of_my_env
The final step required is to install pandas. This can be done with the following command:
conda install pandas
To install a specific pandas version:
conda install pandas=0.20.3
I prefer using the latest version of pandas 1.2.3
However the first method should solve your problem. Always restart your notebook by closing and reopening it.
I will stick around to see if you are winning. But this will resolve your problem. The problem is caused by the versions of numpy and pandas

I fixed this type error downgrading numpy version to 1.16.5.
Try it!
Use code below in your jupyter notebook to downgrade your numpy:
!pip install numpy==1.16.5
My pandas version: 0.24.2
Here's a link to the numpy issue associated with this error: https://github.com/numpy/numpy/issues/18355. A succinct fix is given there (in https://github.com/numpy/numpy/issues/18355#issuecomment-1029684903):
pip install --upgrade numpy
pip install --upgrade pandas
downgrading to numpy==1.19.5 works
Use below command to downgrade in anaconda prompt:
python -m pip install numpy==1.19.5
The issue is because of the non-compatibility of NumPy and pandas versions. I couldn't downgrade my NumPy for some odd reasons as others suggested from Anaconda. But found this link helpful
Downgrading pandas
to 1.3 and with the existing NumPy version set at 1.20.1, helped me to overcome this issue.
Just go to the terminal provided in Jupyter Notebook by clicking "New" and then "Terminal" inside "New" and type:
pip install pandas --upgrade
this will fix the error
as it worked for me.
I fixed it by updating all packages in my Anaconda Navigator Environments
In my case, restarting the kernel fixed the error. Hope it saves someone time as I was reading pandas source code to figure out what the hell was happening :))
U might have the latest version of NumPy which may not be compatible, so downgrade your NumPy version. I have downgraded to 1.17.2
I tried to work with Basemap packages in Python 3.x but, when I try to install the packages in my IDE Pycharm, it gives me this error:
Could not find a version that satisfies the requirement Basemap (from versions: )
No matching distribution found for Basemap
You are using pip version 10.0.1, however version 19.0.3 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
Anyone knows how can I do to install that packages correctly?
(Python 3.x, Pycharm, Windows 10)
You can read on their github that the package was deprecated and they recommended to use cartopy instead:
Source:
https://github.com/matplotlib/basemap
⚠️ Warning: this package is being deprecated in favour of cartopy.
I also ran into a similar problem and the above two solutions did not work for me.
And as you can see here https://github.com/jakevdp/PythonDataScienceHandbook/issues/72#issuecomment-301008464
It is no longer possible to install it via pip, rather try this:
conda install -c conda-forge basemap
You can try to install basemap using precompiled windows binaries.
Download the basemap whl file that is most applicable to you from
here.
Run pip install path_to_the_downloaded_whl on pycharm terminal.
You can install basemap library easily by conda. First of all, you must install conda, then you can create a virtual environment by conda create -n bm python=3.6 (you can use any word you like to replace bm) and activate it by conda activate bm . When command line starts with (bm), you can run conda install basemap to automatically install the library. After that, usually you can use basemap in your python code.
Good luck.
I'm not sure what's going on here. I installed Python with Anaconda, there are no previous versions of Python installed. Everything works fine with Spyder, Jupyter Notebooks, or within Anaconda prompt itself. When I try to run numpy or pandas in cmd, I get an error. When I run them in Anaconda prompt, no issue.
Looks like both prompts are pointing to the exact same installation of Python. I've even ran python.exe from the Anaconda install folder and get the same error.
My Environment Variable path points to C:\Anaconda , where the python.exe is found. Any ideas as to what's going on?
Edit: I noticed I import numpy on the conda screenshot and I'm trying to import numpy on the cmd screenshot. Importing either pandas or numpy on conda loads it successfully.
Edit 2: Opening python.exe within the Anaconda folder gives the same output. Can't import numpy/pandas. Opening Anaconda Navigator -> base (root) -> Open with Python successfully imports numpy/pandas. How can the python.exe within Anaconda not detect libraries installed by Anaconda... yet running Python within Anaconda Navigator works?
Edit 3: SOLVED Ended up uninstalling and reinstalling both Pandas and Numpy through Anaconda prompt. Really odd but now both packages work regardless if I use Conda prompt or cmd.
Try upgrading the pip first and then try to uninstall if they are already present in the below order.
pip uninstall pandas
pip uninstall numpy
pip install pandas
pip install numpy
I have just installed pandas_datareader using pip install pandas-datareader which ran successfully.
Now I am trying to use it for a tutorial and I am getting this error when I try to import.
import pandas_datareader as pdr
ModuleNotFoundError: No module named 'pandas_datareader'
This is the link to the tutorial.
https://www.datacamp.com/community/tutorials/finance-python-trading#gs.DgsO1BY
Any ideas?
Type into Terminal:
pip install pandas_datareader
That's it
Ok the following steps resolved the "No module named 'pandas_datareader" issue for me. To be clear, my situation was such that I had already installed pandas_datareader via pip install pandas_datareader but the "No module named 'pandas_datareader" error still kept popping up whenever I ran a .py code that imports pandas_datareader.
If you are in the same situation as I was (on Mac), this may help you.
Step 1: Uninstall the pandas_datareader package first:
via terminal, type pip uninstall pandas_datareader
it will prompt you asking for a y/n answer to proceed with the uninstallation
type 'y'
Step 2: Restart your IDE if you were using one
in my case, I was using MS VSC (Visual Studio Code)
Step 3:: re-install pandas_datareader package
again via terminal, type pip install pandas_datareader
your terminal may show you a bunch of "pre-installed" pandas_datareader package with message "Requirement already satisfied..."
ignore those.
Step 4: Run your python code again
the "No module named 'pandas_datareader" error should be gone this time round.
Hope this helps.
In your Anaconda Prompt, do this : pip install pandas_datareader
All the other methods didn't work for me.
In command prompt:
conda install -c delichon pandas_datareader
This is working fine on 22nd sept 2019
make sure to update pip.
For me, Import pandas_datareader worked from the command prompt while using python but did not work in jupyter.
From inside jupyter in a cell, I ran pip install pandas_datareader
I got a whole host of "Requirement already satisfied" messages
But at the very end, I was given this very important message. Successfully installed pandas-datareader-0.8.1 Note: you may need to restart the kernel to use updated packages In Jupyter notebook.
There is a kernel menu command sitting between cell and widgets. The restart command is in that drop-down menu option. In my case, this restarting of the kernel was the solution to my " No module named 'pandas_datareader' " all along.
Had the same issue. This resolved it for me:
after activating the env, run:
pip install pip --upgrade
pip install pandas-datareader
pip install jupyter (as i was using a jupyter notebook)
However, if you are running anaconda, use:
conda install -c anaconda pandas-datareader
I had the same problem. I tried pip install pandas_datareader in my Anaconda Prompt and the problem was solved. For some reason, it didn't work in command prompt.
Got this error even though I had pandas_datareader installed. Running on Windows. py -3 -m pip install pandas_datareader in the command prompt didn't work. Same in anaconda prompt didn't work. pip uninstall pandas_datareader followed by pip install pandas_datareader and a reboot finally fixed my problem.
TLDR if running on a Windows machine, uninstall pandas_datareader if you have it (pip uninstall pandas_datareader) and then reinstall with 'pip install pandas_datareader'.
You may consider upgrading your pandas with:
pip3 install --upgrade pandas
I had the same issue installing through my terminal. Since I'm using Anaconda Navigator, I tried the CMD.exe Prompt and inputted "conda install -c conda-forge pandas-datareader".
Jupyter notebook now works like a charm.
I was having this same issue in Jupyter Notebook, where it wasnt recognizing pandas_datareader, even though it said that it was installed successfully in anaconda prompt.
I figured out that my jupyter notebook wasnt opening up in my environment. I activated my environment in Anaconda Prompt and then did conda install nb_conda_kernels. When I opened up Jupyter notebook and checked my env, I was in the correct one, and it recognized my pandas_datareader import. You can check your environment using:
import sys
print(sys.prefix)
This is a SO thread that helped me: Conda environments not showing up in Jupyter Notebook
I was having the same issue. I tried pip install pandas-datareader, pip install pandas_datareader, python3 -m pip install pandas_datareader on termianl, I see message saying I have successfully installed the package but none of them worked. I use Pycharm as my IDE and when I checked File-->Setting-->Progect:File-->Python interpreter, pandas-datareader is not in the package list. I use anaconda as my python Interpreter. So, just added the package into the interpreter and finally worked.
if you facing this error ,you have have to install pandas_datareader.
you can install this package by Jupyter notebook also.
"pip install pandas_datareader"
enter image description here
Go to C:\Users\[UserName]\AppData\Roaming\jupyter\kernels\python3 and open up kernel.json. Check the first argument is pointing to a Python 3 environment/the environment you installed pandas_datareader to.
If you are facing this issue in Jupyter Notebook, just restart the kernel within the IDE.
-Make sure u have installed pandas_datareader with "pip install pandas_datareader"
-Click on the tab named 'kernel'
-Click Restart
Your Problem will be resolved
I've installed successfully python2.7 with ucs4 format.
If I install the numpy with: sudo pip install --upgrade numpy, it works and I can use it, but installing by this way only put numpy in my dist-packages, however it's needed to be in site-packages. (because Jepp can find them only there)
Thus I downloaded the numpy tar file, I buildt it (sudo python setup.py build) and installed it (sudo python setup.py install), but it gives me undefined symbol: PyUnicodeUCS2_FromUnicode. It seems for me, it installed numpy with ucs2.
How could I force to install numpy with ucs4?
(I've read this article: Numpy needs the ucs2 but EPD is not the solution for me)
Any idea may help me!
Thanks in advance.
I simply copied the installed files from dist-packages to site packages. If someone has a better solution, please inform me.
