2 years ago I'm also getting this error. The issue is actually coming from failure to install PySide (one of the dependencies). When I try to just separately install PySide using
pip3 install PySide
I get the same error as you
AttributeError: module 'subprocess' has no attribute 'mswindows'
After googling around, this error seems to be a problem with PySide's compatibility with python3. This package (pyflowgraph) requires PySide<1.2.4 and >=1.2.2, but as far as I can tell, Python3 now works with PySide2 and PySide is deprecated. In general I get the sense that pyflowgrah is not configured to work with Python3. It could probably be fixed by updating the dependencies, but I don't really feel like digging into that. I was able to install by running
pip2 install pyflowgraph==0.0.2
but this isn't ideal, since most people (including myself) are using Python3 environments.
I'm trying to install PyFlowGraph in conda environment using PIP but the installation is failing with given error.
