run error when train P net

[anna0709]

I want train the p net with cpu cause I have compiled the mxnet with cpu(unable cuda). but when I run "python -u ./example/train_P_net.py --gpu=-1", ther are lots errors as follow:

@anna0709 hi, anna, do you have solved this problem, i have meet the same problem.

[bingo00]

possible I found a solution
As this problem occur with

include/mxnet/base.h:295: Please compile with CUDA enabled for cuda features
include/mxnet/base.h:295: Please compile with CUDA enabled for cuda features

I found my python package 'mxnet' is not a package with cuda
Then I go to 'https://pypi.org/' and download the package of mxnet with my cuda version
and reinstall with pip, and now I can train with the py script
