Could not import matplotlib.pyplot about matplotnode

[mateogianolio]

Thanks for submitting an issue, I will have to test on a VM with Ubuntu. I'll get back to you if I find the cause. Is the error message exactly the same as below?

Could not import matplotlib.pyplot.

Thank you for your reply. Here is the exact error message:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!                                                            
Importing the multiarray numpy extension module failed.  Most             
likely you are trying to import a failed build of numpy.   
Here is how to proceed:       
- If you're working with a numpy git repository, try `git clean -xdf`
  (removes all files not under version control) and rebuild numpy. 
- If you are simply trying to use the numpy version that you have installed: 
  your installation is broken - please reinstall numpy.  
- If you have already reinstalled and that did not fix the problem, then: 1. Check that you are using the Python you expect (you're using ),
     and that you have no directories in your PATH or PYTHONPATH that can 
     interfere with the Python and numpy versions you're trying to use. 
  2. If (1) looks fine, you can open a new issue at 
     https://github.com/numpy/numpy/issues.  Please include details on:         
     - how you installed Python                 
     - how you installed numpy 
     - your operating system
     - whether or not you have multiple versions of Python installed
     - if you built from source, your compiler versions and ideally a build log                
     Note: this error has many possible causes, so please don't comment on                                                    
     an existing issue about this - open a new one instead.

Hi, tested on VM with ubuntu 18.04 and I could reproduce your error. After some digging I managed to fix it, so I just published 0.3.2. I have tested it and it seems to work now. Please tell me if you still have problems and I will reopen this issue.

Hi, unfortunately it still crashes. Now

Erreur de segmentation (core dumped)

is the only message.
