lebeg commented on issue #14087: Poor performance of the libmxnet if OMP_PLACES environment variable is present URL: https://github.com/apache/incubator-mxnet/issues/14087#issuecomment-479408995 Just to make a few connections between tickets: Here was an attempt to remove bundled conflicting OpenMP library: https://github.com/apache/incubator-mxnet/pull/12160 [Link](https://lists.apache.org/thread.html/4827f0f742b6e7e070da350ea81226d059401527f3072ce8b33c1fdf@%3Cdev.mxnet.apache.org%3E) to the stale dev list discussion. A proposal from my side for a robust and stable solution is to make a openmp environment checking script that would: * install a performant openmp (from Intel, for example) if not already present * issue a warning that conflicting libs were found and ask for uninstallation (check `LD_LIBRARY_PATH`) * symlink all variants of openmp lib (`gomp`, `iomp`, `omp`) to the same lib * should work in virtual environments (pipenv, virtualenv, conda etc)
