I have installed Ancaconda3 and Tensorflow. When I try to import Tensorflow in python shell I receive the following error:
ModuleNotFoundError: No module named 'numpy.core._multiarray_umath'
ImportError: numpy.core.multiarray failed to import
The above exception was the direct cause of the following exception:
Traceback (most recent call last): File "", line 980, in _find_and_load SystemError:
<class '_frozen_importlib._ModuleLockManager'> returned a result with
an error set ImportError: numpy.core._multiarray_umath failed to
import ImportError: numpy.core.umath failed to import
I am not sure what the problem is as numpy is installed on my system and can be successfully imported in python.
I am using Windows10.
I also had the same issue.
It got resloved once I upgraded the numpy from 1.15.4 to 1.16.1.
If you're using pip:
pip install numpy --upgrade
Numpy that came with Anaconda3 is of version 1.15.4. so i upgraded and it worked.
Side note: if you're also using scikit-image in your script, be aware that numpy 1.16.3 has a conflict with old versions of scikit-image (e.g. you may get ImportError: cannot import name '_validate_lengths'). In that case, pip install --upgrade scikit-image from terminal solved the issue for me.
Kindly check whether you have installed the numpy package from pip. Because if you are running on conda evironment, then all packages need to be downloaded from there.
Please use the below mentioned statement for this purpose
conda install -c anaconda numpy
Also make sure that the numpy version supports the Python version you are using.
You can use two options in python 3.6
Install
py pip -m install numpy==1.14.5
Upgrade
py pip install numpy --upgrade
Note: the version most recently is 1.14.5
I also had this issue with python 3.8.9 and Numpy 1.24.1.
Downgrading to Numpy 1.21.0 fixed the issue.

I am just a beginner in python.
I have a requirement of converting a JSON Object into a YAML file and trying to import ruamel.yaml.
I did install the command pip3 install ruamel.yaml and my python list package shows that it's available.
site-packages % pip3 list
Package Version
------------------ ---------
certifi 2021.10.8
charset-normalizer 2.0.11
idna 3.3
pip 22.0.3
pytz 2021.3
PyYAML 6.0
requests 2.27.1
ruamel.yaml 0.17.21
ruamel.yaml.clib 0.2.6
setuptools 60.9.3
urllib3 1.26.8
Whereas when I am trying to import and use it in the python script it is giving me below error.
Import "ruamel.yaml" could not be resolved
Could someone please suggest how to resolve this.?
When Python cannot find a module you get an error looking like:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named ruamel.yaml
This might be because you are using some non-standard installation/execution environment, or because you try to run this from an editor. Some of those don't understand the concept of namespaces in Python.
It could also be that pip3 is not installing for the python that you are using to run the program. That is easy to check by installing some other package using pip3 and trying to import that.
In either case make sure you test your program running with the python that corresponds to pip3 ( using type pip3 or which pip3 resp type python ), or install using:
python -m pip install ruamel.yaml
and then run the program with python your_prog.py

I did try re-installing numpy, pandas and mkl-services to no avail. Strangely, the code executes fine in Spyder, but simply won't run via "double-click" pointing towards C:\ProgramData\Anaconda3\python.exe
What am I doing wrong? Thanks!
Thanks to Yo_Chris I was able to solve my problem by de-/re-installing first pandas using pip and then doing the same for numpy.
pip uninstall pandas
pip install pandas
pip uninstall numpy
pip install numpy
As a note I did try those steps with conda before, but that did not solve the problem. I did think back then that conda and pip work the same. Apparently that is not the case.
Thanks again for letting me try pip!
I've installed rpy2 through pip install rpy2. After this in a Jupyter notebook the import works fine:
import rpy2
print(rpy2.__version__)
which returns 3.1.0.
However when I type this import rpy2.robjects as robjects, I get the following error:
ValueError: The system "%s" is not supported.
Does someone know where this error comes from and how to solve it?
I had exactly the same problem.
I uninstalled the package and reinstalled it with conda (as I use Jupyter notebook through Anaconda):
conda install rpy2
Doing this it worked just fine.
The version installed was 2.9.4. There may be an issue with the version 3.1.0 I believe.
I have a similar problem. I had previously installed rpy2 2.9.5 withpip3 install rpy2 and it worked fine. However, today I tried updating it with pip3 install --upgrade rpy2 and got the following error:
Collecting rpy2

SyntaxError: invalid syntax
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-irk23ljv/rpy2/
I can't just stick to the older version because what I'm actually trying to do is to install another Python package that has rpy2 listed as a dependency. The install fails with the same error message.
Any update on the subject?
Edit
It looks like this might be a compatibility issue with Python 3.5 -- see https://bitbucket.org/rpy2/rpy2/issues/580/installing-rpy2-on-travis-with-pip. I've just opened an issue here: https://github.com/rpy2/rpy2/issues/356
I am trying to learn pandas and want to load some stocks data. I was following a course which advised me to load pandas.io.data, but this did not work as io.data was depreciated. So I decided to use pandas-datareader instead. But I am struggling to instal it on mac in Anaconda (Jupiter notebook).
First time I run import pandas_datareader as pdweb I got ModuleNotFoundError: No module named 'pandas_datareader'. Not surprising as I never used this before so I run pip3 install pandas_datareader in Terminal which successfully installed itself. However, Jupiter notebook is still giving me the same error. At this point, I tried running in Terminal conda install -c https://conda.anaconda.org/anaconda pandas-datareader but it did not work as -bash: conda: command not found.
Please help. I am looking for a detailed explanation as I am not too techie.
What I run in Jupiter
import numpy as np
from pandas import Series, DataFrame
import pandas as pd
import pandas_datareader as pdweb
import datetime
Result
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-6-da568f513c93> in <module>
2 from pandas import Series, DataFrame
3 import pandas as pd
----> 4 import pandas_datareader as pdweb
5 import datetime
ModuleNotFoundError: No module named 'pandas_datareader'
Just run
conda install -c anaconda pandas-datareader
as per instructions here.
In my experience, if you're using conda, you should never install with pip unless you're sure conda doesn't have it. Try searching anaconda.org to see which -c source to use.
The problem was with conda command not being set up during the installation of Anaconda. I solved this by removing Anaconda with App Cleaner & Uninstaller Pro (free soft) and reinstalling later version.
After reinstallation of Anaconda command below worked like a charm.
conda install -c anaconda pandas-datareader
If you using Anaconda and still have issues installing panads-datareader using the conda command 'conda install -c anaconda pandas-datareader'. or the installation is successful but the import pandas_datareader.data as web still gives an error.
Locate where your 'site-packages % ' directory and cd to the site-packages % dir and then run the installation command 'conda install -c anaconda pandas-datareader '. It will work.
For the install, try using
pip
instead of
pip3
I am getting error while running "from lxml import tree" on python3.6
>>> import lxml
>>> from lxml import etree
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'etree'
The same working on python3.4, I have tried many things to troubleshoot as below but didn't success.
python -m pip uninstall lxml
python -m pip install lxml==3.6.0
pip install -t /usr/local/lib/python3.6/dist-packages lxml==3.6.0
Just in case anybody has similar issue.
I also encountered this problem using Python3.6.
Just by uninstalling lxml and installing it again with pip the issue is resolved.
Got this working in Lambda with python 3.6
Turns out lxml wraps c libraries that are compiled for a certain processor architecture (I think)
Use precompiled binaries for lambda here: https://github.com/JFox/aws-lambda-lxml
For Windows:
After having the same problem at the instance of my Windows 2019 server, Python 3.8 and Anaconda, I downloaded the corresponding whl package, installed it with
pip install lxml-4.6.3-cp38-cp38-win_amd64
It now works without problem.
I have the same issue when deploying an Azure python function using version 3.9. I redeployed with 3.6 in Azure an everything worked fine.
Had the same while running the code in VS code.For me I got it resolved by changing the interpreter in VS code from 32-bit to 64-bit.
