The more information you provide, the more likely people will be able to help you. ## Environment info Operating System: RHEL 6.9 (2.6.32-696.el6.x86_64) Compiler: Package used (Python/R/Scala/Julia): Python MXNet version: Or if installed from source: git clone --recursive https://github.com/dmlc/mxnet (Installed from source) MXNet commit hash (`git rev-parse HEAD`): If you are using python package, please provide Python version and distribution: Python 2.7.10 If you are using R package, please provide R `sessionInfo()`: ## Error Message: Please paste the full error message, including stack trace. I have installed mxnet at this dir: ~/mxnet/mxnet PYTHONPATH is set to ~/mxnet/mxnet/python A. OpenBLAS used: 1. git clone "git://github.com/xianyi/OpenBLAS.git" 2. cd OpenBLAS 3. make TARGET=SANDYBRIDGE ( our processor is Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz which is haswell but it was giving this error with `make` command ./kernel/x86_64/dtrmm_kernel_4x8_haswell.c:77: Error: no such instruction: vpe rmpd $0x1b,%ymm3,%ymm3' ../kernel/x86_64/dtrmm_kernel_4x8_haswell.c:78: Error: no such instruction:vpe rmpd $0xb1,%ymm2,%ymm2') So I changed TARGET=SANDYBRIDE 4. Installed OpenBLAS with make PREFIX=dir install B. 1. Installed mxnet with USE_BLAS=openblas and USE_OPENCV=0 and specifying path of OpenBLAS in mxnet/make/config.mk file. 2. make -j4 (Successful as it generated lib/libmxnet.a and libmxnet.so) 3. export PYTHONPATH=~/mxnet/mxnet/python/ 4.
