undefined symbol: MPI_UNWEIGHTED #63

Closed adyotag closed 10 months ago

adyotag commented 10 months ago

I loaded the intel-mkl module and installed pyina using pip using https://edbennett.github.io/high-performance-python/08-pathos/index.html

However, I'm getting an error upon importing ez_map - ImportError: /home/agupta87/.conda/envs/DEM_SPHERES/lib/python3.8/site-packages/mpi4py/MPI.cpython-38-x86_64-linux-gnu.so: undefined symbol: MPI_UNWEIGHTED

I've tried modifying the path by adding the path to the conda environment, but that didn't work either.

If you are getting an undefined symbol error, this is coming from the C++ shared object MPI.cpython-38-x86_64-linux-gnu.so missing a dependency (often due to an incorrect version of a library being linked in the path). It looks like it's coming from the build/install of cythonized MPI code from mpi4py. I don't think anything can be done from pyina to ensure the MPI library is built/linked to the mpi4py code... you may want to try the mpi4py developers -- or check which version of the libraries are in your path and being linked. I'm going to close this as void, but do feel free to follow up here.
