larroy commented on issue #10856: Failed OpenMP assertion when loading MXNet compiled with DEBUG=1 URL: https://github.com/apache/incubator-mxnet/issues/10856#issuecomment-505129021 Getting crashes in master when using debug version with OpenMP and MKL for development: ``` Assertion failure at kmp_runtime.cpp(6481): __kmp_team_pool == __null. OMP: Error #13: Assertion failure at kmp_runtime.cpp(6481).

OMP: Hint This means that multiple copies of the OpenMP runtime have been linked into the program. That is dangerous, since it can degrade performance or cause incorrect results. The best thing to do is to ensure that only a single OpenMP runtime is linked into the process, e.g. by avoiding static linking of the OpenMP runtime in any library. As an unsafe, unsupported, undocumented workaround you can set the environment variable KMP_DUPLICATE_LIB_OK=TRUE to allow the program to continue to execute, but that may cause crashes or silently produce incorrect results.
