directory error: chains does not exist

[anusurendra]

Hi,

I am able to install PolyChordLite. I did all the installation as root and am able to run the test fine when root. However, when I run the test the script as a regular user I get the following error:

python3.7 run_pypolychord.py
WARNING: Could not preload libmpi.so.If you are running with MPI, this may cause segfaults
--------------------------------------------------------------------------
By default, for Open MPI 4.0 and later, infiniband ports on a device
are not used by default.  The intent is to use UCX for these devices.
You can override this policy by setting the btl_openib_allow_ib MCA parameter
to true.

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

This should now be fixed in the latest version of pypolychord which automatically creates the chains files. Let me know if you don't see this.
