[zcy1065670505]

Hi, When I use Anaconda to install mxnet=1.5.1,like Command:pip install mxnet-cu100==1.5.1,
I can run the example successfully, But when I try to find the 'mx_home', there is no those directions such as follows.
Could you tell where are those directions: ../3rdparty/..
thank you for your kind help!

dmlc_inc=${mx_home}/3rdparty/dmlc-core/include
nnvm_inc=${mx_home}/3rdparty/nnvm/include
mshadow_inc=${mx_home}/3rdparty/mshadow
dlpack_inc=${mx_home}/3rdparty/dlpack/include
mxnet_src_inc=${mx_home}/src/operator
mxnet_common_inc=${mx_home}/src/common
