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-525103793 I think it might be a bug in intel omp library or some sort of interaction, with gnuomp everything works as expected: I compiled without MKL. ``` (py3_venv) piotr@ip-172-31-22-252:0: ~/mxnet_other [master]> python test.py parent pid: 42977 train pid: 43182 10 9... go HybridSequential( (0): Dense(None -> 10, linear) ) (py3_venv) piotr@ip-172-31-22-252:0: ~/mxnet_other [master]> ``` ``` (py3_venv) piotr@ip-172-31-22-252:0: ~/mxnet_other [master]> ldd build/libmxnet.so | grep omp libgomp.so.1 => /usr/lib/x86_64-linux-gnu/libgomp.so.1 (0x00007ff7a8b48000) ``` Seems mixing omp implementations might not be safe after all.
