from numpy import *
from pylab import *
Why am I getting a warning next to both of these lines "unable to detect undefined names"
Because numpy module don't come with python standard library. you should first install numpy by using python pakage manager : pip
if you are in windows then you can run following command in cmd
pip install numpy
to install numpy and then you can import in your python file

If you have multiple python installations, make sure you are installing the package for the correct python version. To install a package for python3.x use python3.x -m pip install {package}
I used to code in Jupyter notebook and importing pandas was never thrown an error. But when I use the same code in Visual Studio Code,
# Import Libraries
from random import seed
from random import randint
import pandas
import numpy
import math
import random
import collections
import itertools
import collections
import matplotlib.pyplot as plt
import seaborn as sns
# %matplotlib inline
I receive the below error.
File "g:/My Drive/M/importlibrary.py", line 5, in <module>
import pandas
File "C:\Users\M\Anaconda3\lib\site-packages\pandas\__init__.py", line 19, in <module>
"Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']
I try to search for several similar issues and most of the solution ask to first uninstall and then install NumPy and Pandas using the below code,
pip3 uninstall pandas
pip3 uninstall numpy
However, I have followed this workaround but the problem did not resolve. The version of python that I am using is,
Python 3.6.8 :: Anaconda, Inc.
Please help if you can.
Is there a reason why you don't install Numpy/Pandas using anaconda (conda install -c anaconda numpy/pandas)? Did you run Jupyter from inside anaconda when it worked? I suggest going to terminal and figuring out where your modules are installed (i.e. if they are inside the anaconda folders, or somewhere where anaconda has access to).
In general, I'd advise against installing python packages for anaconda using pip, just use conda's package manager if you can. This question seems related. In your case, have you tried uninstalling the pip variant and reinstalling using conda?
The problem is resolved by uninstalling the Anaconda. I checked the control panel of the PC and found that there are multiple instances of python. VS Code uses Python 3.6.8 while Anaconda uses python 3.8. So, I uninstall 3.8, and then reinstall pandas,
pip3 uninstall pandas
pip3 install pandas
The error is no more.
I tried importing NumPy to carry out some array operations in Python:
import numpy *
But I got this error message:
ModuleNotFoundError: No module named 'numpy'
What do I do?
If you are using PyCharm, open PyCharm and go to menu File → Setting → Project → Python Interpreter → click on '+' → search and select the required package → install package.
Use the following command
pip3 install numpy
You will get the following response. You see the location.
Use the following as PATH as per direction explained in the previous post.
Requirement already satisfied: numpy in c:\users\-user name-\appdata\local\packages\pythonsoftwarefoundation.python.3.9_qbz5n2kfra8p0\localcache\local-packages\python39\site-packages (1.20.1)
NumPy is installed here, not in "scripts".
NumPy doesn't seem to be installed on your computer, but you can use this command to install it:
python -m pip install --user numpy
Or you can check the installation guide for your distribution here:
Install SciPy
You can simply install NumPy with pip:
pip install numpy
Install NumPy with the pip install numpy command (ignore if already installed).
Import NumPy in either of the three ways:
import numpy
import numpy as np
from numpy import *
After I have reinstalled Anaconda, I can not import NumPy any more on Python 3:
import numpy as np
Output:
ModuleNotFoundError: No module named 'numpy'
I have tried
pip install numpy
I try to install it again, but I get:
pip install numpy
Output:
Requirement already satisfied: numpy in /anaconda3/lib/python3.7/site-packages (1.16.3)
Screenshot of some of the above
This command worked for me
python3 -m pip install numpy
You probably have multiple NumPy versions installed on your system and need to manually delete the old one.
Open Terminal and run:
pip list
Remember or notate the NumPy version from the list
Then run Python in Terminal or write and execute this code in your IDE:
import numpy
print(numpy)
print(numpy.version)
This should print two lines: numpy package location + numpy version like this:
<module 'numpy' from '/usr/local/lib/python2.7/site-packages/numpy/init.pyc'>
1.16.1
If the NumPy version reported here is different than the one reported by pip list, then go to the NumPy package location printed above and delete that package folder
Try importing NumPy now. If you previously installed it, it should work. If you didn't install it then go and install it now. After installation all should work fine.
You are using a Conda environment to run your program. So you should run:
conda install numpy
If you use IDE like PyCharm, it will be easy to install packages by a mouse click (Install packages).
I am trying to import the following statements. My end goal is to generate a word cloud.
I am using enathught canopy python 3.5.2 In the terminal prompt from canopy I ran the command below:
import matplotlib.pyplot as plt
from wordcloud import WordCloud, STOPWORDS
which returned no module names 'pyQt4'
So i tried installing that !pip install 'pyQt4'
output obtained:
Collecting pyqt4
Could not find a version that satisfies the requirement pyqt4 (from versions: )
No matching distribution found for pyqt4
Also I tried !pip install pyplot which again gave the same errorno module names 'pyQt4'
Please help as to what I can do from command prompt?
You need to install pyQt4. If you are using Anaconda, pyQt5 is included. For some package, they require pyQt4. It took me a long time trying to install pyQt4. My solution is download pyQt4 from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4, and install the .whl file with:
pip install some-package.whl
