Difference running python in PyCharm and in terminal

问题

I'm wondering what is the difference when I run a python program from PyCharm or from the command line.

Actually I'm using a library called wand-py (ImageMagick binding).

If I run my program from the command line it works.

Though if I use PyCharm Run or debug it doesn't and I get the following traceback.

/Users/alexisbenoist/Documents/python/papyrus/env/bin/python "/Applications/PyCharm CE.app/helpers/pydev/pydevd.py" --multiproc --client 127.0.0.1 --port 58993 --file /Users/alexisbenoist/Documents/python/papyrus/tets.py

    raise e
wand.exceptions.WandError: wand contains no images `MagickWand-1' @ error/magick-image.c/MagickSetImageAlphaChannel/9504

I'm using the same virtual env in the terminal and PyCharm.

Do you guys know what could cause the problem?

Thanks,

Alexis.
