Problem using scikit-network on windows in PyCharm

[moissinac]

• scikit-network version: 0.19.3
• Python version: 3.6
• Operating System: windows 10 64 bits

Description

Do a simple test in debug mode under the PyCharm IDE

What I Did

Succesfully install scikit-network (checked in console) My test code in PyCharm:

import sknetwork as skn graph = skn.data.karate_club(metadata=True)

Hello,

Thanks for your interest in our package.

Sadly, this issue does not stem from scikit-network but from Pycharm not having a debugger for Cython. It has been a long-time request from the users to have this particular feature and will likely not be implemented soon.

However, as long as you are not using Cython in your tests, you can still use the standard Python debugger. To do so, you can use configurations for testing pure-Python modules only for instance.

Also note that, when using scikit-network from sources, you should generate and compile the corresponding C++ code if you want to run the whole test suite.

I can't easily know if a method of scikit-network uses Cython or not. So, you seem to say that I can't use scikit-network in Pycharm with a simple pip install. I've tried your link about 'configurations', but it seems to apply only for developers of scikit-network (and i get the same error with my source (2 lines, just loading a dataset) Is there a mean to view Cython modules as 'opaque' modules (like call to system functions are not accessible for debuging)

An update to Pycharm solves the problem...
