psutil requirement

[cardosan]

HI, I am working with a package that uses pyprind and seems that there is a prob with psutil. Also doing

pip install pyprind -r requirements.txt
Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'

looks like there is no 'requirements.txt' and this prevents pyprind to work

Sorry for the trouble and thanks for the note! I will add the requirements file later today! In any case, until the new version is uploaded to pip, a

pip install psutil
pip install pyprind

should fix the problem!

[cardosan]

thanks!

I just added the requirements.txt. However, I guess that it would only work locally not via PyPI. I don't want to make psutils a hard requirement via install_requires in the setup.py or so, because it's just an optional package for the non-default monitor=True in pyprind
