mpi4y not working on my machine using pycharm

[Jibran Zaffer]

Hello. I wantred to run a simple program using MPI and mpi4py but it keeps giving me an error when i try to run it through pycharm. I tried running it through command prompt and it worked perfectly fine. Everytime i try to run it through pycharm it says 

ImportError: libmpi.so.12: cannot open shared object file: No such file or directory            
    from mpi4py import MPI    

Building wheels for collected packages: mpi4py
  Building wheel for mpi4py (pyproject.toml): started
  Building wheel for mpi4py (pyproject.toml): finished with status 'error'
Failed to build mpi4py

I'm not a user of PyCharm. 

It is hard to tell exactly what's going on, you provided very little information to even guess what may be wrong in your setup.

A probable cause of your issue is that the Python process running within PyCharm is not getting the LD_LIBRARY_PATH environment variable. 

What Linux distro are you using?

How did you install PyCharm?

How did you configure the Python interpreter PyCharm is running?

How did you install the MPI implementation (which is MPICH, from the libmpi.so.12 shared library name)?
