aaronmarkham commented on issue #13875: importing mxnet causing subprocess to crash URL: https://github.com/apache/incubator-mxnet/issues/13875#issuecomment-455257763 Researching the build logs from the first crash... I see that mkldnn is set to 0 in some of the earlier build routines, but when making the docs, mkldnn files are being built by mshadow: ``` + make docs SPHINXOPTS=-W /work/mxnet /work/mxnet make -C docs html make[1]: Entering directory '/work/mxnet/docs' export BUILD_VER= Env var set for BUILD_VER: sphinx-build -b html -d _build/doctrees -W . _build/html Running Sphinx v1.5.6 making output directory...
