I had a similar issue that I resolved and here is my issue:

I set everything up on python3 but I was using python to call my file for example: I was typing "python mnist.py" ...since I have everything on python3 it was thinking I was trying to use python 2.7

The correction: "python3 mnist.py" - the 3 made all the difference

I'm by no means an expert in python or pip, but there is definitely a difference between pip and pip3 (pip is tied to python 2.7) (pip3 is tied to python 3.6)

so when installing for 2.7 do: pip install when installing for 3.6 do: pip3 install

and when running your code for 2.7 do: python when running your code for 3.6 do: python3

I hope this helps someone!

Working on the django project and faced same problem  This is what I did  Check if you have metaplotlib already simply by writing pip show metaplotlib in the python terminal   If dont  run the command pip install metaplotlib  make sure you have pip downloaded  Run the command pip show metaplotlib again  If the library is successfully downloaded  you can run your project  py manage py runserver

If you are using Python 2  just run   sudo apt-get install python-matplotlib   The best way to get matplotlib is     pip install matplotlib   cause the previous way may give you a old version of matplotlib

First check the version of Python For python2  sudo apt-get install python-matplotlib  For python3  sudo apt-get install python3-matplotlib  If you mismatch the Matplotlib installation and the Python version you will get the no-module-error because no module for that version exits

You have two pythons installed on your machine  one is the standard python that comes with Mac OSX and the second is the one you installed with ports  this is the one that has matplotlib installed in its library  the one that comes with macosx does not     usr bin python   Is the standard mac python and since it doesn t have matplotlib you should always start your script with the one installed with ports   If python your script py works then change the    to      usr bin env python   Or put the full path to the python interpreter that has the matplotlib installed in its library

Comment in the normal feed are blocked  Let me write why this happens  just like when you executed your app   If you ran scripts  python or ipython in another environment than the one you installed it  you will get these issues    Don t confuse reinstalling it  Matplotlib is normally installed in your user environment  not in sudo  You are changing the environment    So don t reinstall pip  just make sure you are running it as sudo if you installed it in the sudo environment

The file permissions on my virtual environment directory and my project directory were not correct and  thus  would not allow me to install the proper packages  I upadated them by running  sudo chown user user -R  project folder  sudo chown user user -R  environment folder   In the above your should use your own usernames in place of  quot user quot   The -R recurses through all subfolders and files
