Pychrono import failure

[Maksym Riabov]

Hello,
I’m trying to import pychrono to my python code, and it seems to not work.

I’ve first installed it pychrono from tarball as described in in https://api.projectchrono.org/pychrono_installation.html, but python simply can’t find my package this way ( Import "pychrono" could not be resolved.)

I’ve also tried to install it from conda install pychrono, but it fails with 

ImportError: libChronoEngine.so: cannot open shared object file: No such file or directory

The python interpreter seems correct, it’s the only one installed python 3.9.

What is wrong?

Full traceback from usual conda install:

From pychrono from tarball:
