Question

我尝试按如下方式安装mxnet：操作系统： RHEL 6.9（2.6.32-696.el6.x86_64）编译： gcc（GCC）5.3.0也尝试过6.2.0

一个。 OpenBLAS构建为

 1. git clone https://github.com/xianyi/OpenBLAS.git
 2. cd OpenBLAS
 3. make DYNAMIC_ARCH=1 NO_AVX2=1
 4. make PREFIX=~/test/OpenBLAS-1.0 install

B中。 mxnet install

 1. git clone --recursive https://github.com/dmlc/mxnet
 2. cd mxnet
 3. modified make/config.mk as follows
    USE_OPENCV = 0  
    USE_BLAS = openblas (#Line no : 93) 
    ADD_LDFLAGS = -I/home_dir/test/OpenBLAS-1.0/lib
    ADD_CFLAGS =  -I/home_dir/test/OpenBLAS-1.0/include

 4. make -j4 #It successfully created lib dir  containing libmxnet.a and libmxnet.so

然后导出PYTHONPATH作为导出

`PYTHONPATH=~/test/mxnet/python/`

在交互模式下运行python后，我收到以下错误：

[c244728_lx@brainiac-login-0001 lib]$ python --version
