larroy edited a comment on issue #14979: [BUG] Using a package with MKL and GPU versions, using python to open a new process will cause an error URL: https://github.com/apache/incubator-mxnet/issues/14979#issuecomment-495784143 Looks like an OpenMP related problem. Since the stack trace has libc on it I suspect we are re-entering MXNet on pthread_at_fork handlers due to Python multiprocessing interaction. Since you are using multiprocessing, this could be done above the python level to avoid this situation.
