Hi,

I need some help with installing Pysph. As I was testing after installing Pysph and all dependencies, I'm getting the following message:

This is fixed in master but if you installed pysph from pypi then you should also install numpy-stl. pip install numpy-stl and that should fix this test error.

cheers,

Dear reader,

This issue dates from 2019, but I just installed PySPH via pip3 and got the same problem so apparently this issue is still there. Luckily, pip3 install NumPy-stl solved the issue. I did install all dependencies as mentioned in the installation guide before trying to run the tests. Unfortunately, this was not the only problem. After installing numpy-stl I was able to run the pysph test and 17 fails showed up. I suppose there are more packages missing. Is it possible to update the dependencies list for installing and using pysph on Ubuntu 20.04?

Kind regards,

Stephan
