Attempting to install Python PIL module fails with "Non-zero exit code"

I really don't get why Python is so difficult to get up and running properly.
Anyway, I've just fresh installed Python 3.7 and PyCharm. I want to get the Python Imaging Library working within my project, but when I try to install it using PyCharm I get the following error:
pip install PIL
Non-zero exit code (1)
Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at 'C:\Users\Jake\AppData\Local\Programs\Python\Python37-32\python.exe'.
Command output:
Collecting PIL
Could not find a version that satisfies the requirement PIL (from versions: )
No matching distribution found for PIL
You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
I've attempted to run python -m pip install --upgrade pip from a CMD prompt, but I then get this error:
Fatal Python error: Py_Initialize: unable to load the file system codec
ModuleNotFoundError: No module named 'encodings'
I just tried to install NumPy using the exact same method for PIL and Numpy installed without any issues whatsoever. This leads me to think that maybe PIL isn't supported for Python 3.7?
Can someone explain to me what the issue is here and help me with importing modules into my PyCharm project?

PIL is not maintained anymore. You can use Pillow instead, a more active fork of PIL.
pip install Pillow

Pillow is installed, but still getting "ImportError: No module named PIL"

I did find this question asked by few more people, but none of those exactly met my situation, so asking here myself.
I've (rather had) two versions of Python (2.7 and 3.4.3) on my Mac running the latest MacOS High Sierra. As I understand, the v2.7 comes as default installation with the MacOS. And I installed the 3.4.3 (from .dmg file downloaded from the python site). Thus now, the python command defaults to the 2.7, while python3 points to the 3.4.3 in the terminal.
While trying to learn, I tried a python script that uses
import PIL and from PIL import Image
But when running, this gave the error ImportError: No module named PIL.
Upon research on google, I figured out to install PIL and Pillow using
sudo pip install Pillow
It installed correctly, but I'm still getting the same error.
To remove the confusion, I decided to remove the python 3.4.3 from the system. But even after it's removed, I still get the same error.
Even pip list displays Pillow 5.1.0 alright.
So right now, I've only Python 2.7, and the error persists, while Pillow is also in there.
which python gives /opt/local/bin/python as the path.
Does any of the above ring a bell? Any ideas, what else could be missing here?

Phew, finally found the issue. Thanks #Yash for the pointers.
Incidentally I did a which -a python and surprisingly got this output:
/opt/local/bin/python
/usr/bin/python
Damn, I don't remember when I installed a second 2.7 version on the /opt/local/bin folder (probably via macports). Alright, removed the confusion, deleted this python, so now I'm left only with the system installed python at /usr/bin.
And now the imports all run perfectly fine as expected. :-)

Try this,
sudo pip install image
I hope it works! One more thing, do check if you're running python3 filename.py instead of python filename.py, if you want to install it for Python 3, run the command,
sudo pip3 install Pillow

Basic Installation:
pip install Pillow
Windows Installation:
pip install Pillow
Reference: https://pillow.readthedocs.io/en/stable/installation.html

Try this. It worked for me
pip install --upgrade --force-reinstall pillow
If you get something like access denied error run the below command
pip install --upgrade --force-reinstall pillow --user

installing opencv for python 2.7 on a MAC

I installed opencv via the command pip install opencv-python and then when I import cv2 in python I get the error ImportError: dlopen(/Library/Python/2.7/site-packages/cv2/cv2.so, 2): Symbol not found: _clock_gettime
I would like to install opencv for python 2.7 on a mac. How can I resolve this error ? I am using El Capitan.
I installed opencv prior to this using brew install opencv but then I uninstalled it using brew uninstall opencv before using pip.

This works !
sudo pip install opencv-python==3.3.0.10
El Capitan has an issue detailed here http://answers.opencv.org/question/182067/import-cv2-throws-symbol-not-found-_clock_gettime/
In order to circumvent this issue, I rolled back to an earlier version of opencCV.
A trick to check the available version with pip do
sudo pip install opencv-python==
This will return all the available version and then you can try the ones that work for you.
Dont forget to pip uninstall when moving to a different version

It looks like this is an issue with python-opencv and the mac operating system That you are using. From the link below it looks like Apple changed something to do with _clock_gettime function, meaning the maintainers of python-opencv will need to update.
The commenters on the post below managed to fix the issue by upgrading to Sierra

How to install gensim on windows

Not able to install gensim on windows.Please help me I need to gensim Immediately and tell me installation steps with More details and other software that needs to be installed before it. thanks

First you need to install NumPy then SciPy and then Gensim (assuming you already have Python installed). I used Python 3.4 as I find it easier to install SciPy using version 3.4.
Step 1) Install Numpy:
Download numpy‑1.13.1+mkl‑cp34‑cp34m‑win32.whl from here
note that in cp34-cp34m 34 is version of Python you are using. So download appropriate file
Open command prompt and go the folder in which you just downloaded the file and install Numpy using following command:
pip install numpy‑1.13.1+mkl‑cp34‑cp34m‑win32.whl
You should get successfully installed numpy message
Step 2) Install SciPy:
Follow the same link as above and download the scipy‑0.19.1‑cp34‑cp34m‑win32.whl file.
Install it using the same instructions than in Step 1 but with this file name. The command is the following:
pip install scipy‑0.19.1‑cp34‑cp34m‑win32.whl
You should get this message successfully installed scipy
Step 3) Install gensim:
Follow the link in step 1 and download gensim‑2.3.0‑cp34‑cp34m‑win32.whl (the appropriate version for your system)
Install it using the instructions in Step 1 (with this file name) with following command:
pip install gensim‑2.3.0‑cp34‑cp34m‑win32.whl
You should get this message successfully installed gensim
Now in a Python shell try:
import gensim
It should be successfully imported
NOTES:
Make sure pip is in your environment variables (add C:\python34\scripts to your environment variable).
Make sure to download all the packages according to the Python version you are using.

gensim depends on scipy and numpy.You must have them installed prior to installing gensim. Simple way to install gensim in windows is, open cmd and type
pip install -U gensim
Or download gensim for windows from
https://pypi.python.org/pypi/gensim
then run
python setup.py test
python setup.py install

I struggled with this a bit today trying to figure out if I needed a python 2.7 environment or if I could use my 3.5. I ended up doing this from an Anaconda 3.5 install:
conda install -c anaconda gensim=0.12.4
After a few hours of trying various things, suddenly it all worked on 3.5. My error was that it kept failing to install Scipy. I tried starting over with the conda install and just worked.
See: https://anaconda.org/anaconda/gensim

I strongly suggest using anaconda where the installation of all the packages is very easy.
The command for installing genism and all of its necessary packages on windows using anaconda python 3.7 is below.
conda install -c anaconda gensim

I followed the instruction on https://radimrehurek.com/gensim/install.html which then successfully installed the fast version of Gensim (3.8.0) on Windows:
conda install -c conda-forge gensim
PS:
The following did NOT install the fast version on Windows:
conda install gensim

After attempting some of the above ideas, there was still a "hiccup" with gensim but the error was something else related to punkt. The following (where the interest is the second line)...
import nltk
nltk.download('punkt')
import numpy
import scipy
import gensim
...did the trick. I used conda and not pip but do not believe that mattered.
Versions: latest python
Machine: Windows 10 (latest updates as of 8/2020)

installing opencv for python in Ubuntu 14.04

I ran the following command on terminal
$ sudo apt-get install libopencv-dev python-opencv
This installed opencv version 2.4.10.
After that I open python in terminal and try to import opencv as follows
>> import cv2
This gives me an error :
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named cv2
I also tried using import cv, import opencv, etc. but I am getting the same error.
Do I need to follow some more steps to configure opencv for python ??

This happens when python cannot refer to your default site-packages folder where you have kept the required python files or libraries
Add these lines in the code:
import sys
sys.path.append('/usr/local/lib/python2.7/site-packages')
or before running the python command in bash move to /usr/local/lib/python2.7/site-packages directory. This is a work around if you don't want to add any thing to the code.
OR
try adding the following line in ~/.bashrc
export PATH=/usr/local/lib/python2.7/site-packages:$PATH

There is an installer for Ubuntu 16.04, and it may work well on Ubuntu 14.04, you could have a try. I have used it to install on Ubuntu 16.04 and it succeed!
An interactive installing script for install openCV on Ubuntu 16.04 LTS

The Opencv version(2.4.10) installed is for python2x version.
I think you are trying to use cv2 in python3x version (which might be set as default for python)
Open python2 on terminal (use command python2 instead of python)
>> import cv2
This will work.

I think it is better that you just install Anaconda python distribution.
https://www.continuum.io/downloads
You can find wealth of tutorials in the internet on how to install it in your system. And trust me, it is VERY EASY to install.
After you have install your Anaconda python distribution, you can install OpenCV 3.1 by the following commands. Note that you should have an internet connection.
# if you are using Anaconda for Python 2.7
conda install -c menpo opencv
The above code should install OpenCV 3.1 in your anaconda python 2.7
# if you are using Anaconda for Python 3.5
conda install -c menpo opencv3
The above code should install OpenCV 3.1 in your anaconda python 3.5
Then to verify that you have successfully install OpenCV 3.1 in your system, you can issue the following command in the python interpreter:
# import the opencv library
import cv2
# prints the version of the OpenCV installed in your system
cv2.__version__
That's it. I hope that helped you =)

Try using this:
sudo apt-get install python-opencv opencv-dev python-numpy python-dev
