Library missing #20

Closed mklissa closed 5 years ago

mklissa commented 5 years ago

Hi there,

I proceed to install the mentionned necessary, but when I try using CoinRun in interactive mode, I get:

    from mpi4py import MPI
ImportError: dlopen(/anaconda/envs/coin/lib/python3.6/site-packages/mpi4py/MPI.cpython-36m-darwin.so, 2): Library not loaded: /usr/local/opt/gcc/lib/gcc/7/libgfortran.4.dylib
  Referenced from: /usr/local/opt/mpich/lib/libmpi.12.dylib
  Reason: image not found

Thanks

Looks like you should uninstall and reinstall mpi, and probably mpi4py as well. I'm afraid this is not an issue with coinrun.
