Description

Hi, @kaizhang . Thanks for developing this fantastic tool. When I was running the function snap.pp.mnc_correct with my own data in a Jupyter notebook, the kernel died after several minutes and a core file was produced immediately. The error message and the core file are shown below

I checked the log of the Jupyter Notebook, and it said "OpenBLAS warning: precompiled NUM_THREADS exceeded, adding auxiliary array for thread metadata". I am not sure if it's related to the error. Could you take a look at this error for me? Thanks very much!

Research direction

Start by reproducing the crash from the Jupyter notebook at snap.pp.mnc_correct using the reporter's own data, then inspect the notebook log and generated core file. Check whether the OpenBLAS warning appears immediately before the kernel dies. Done means identifying a reproducible cause and documenting or verifying a fix for the core-file-producing crash.
