Attribute error: Demo.py

I got this error when I was trying to run demo.py. Can anyone help me?

I solved this problem, don't run

git checkout 62ecb60 git submodule update

Hi，I spent one day and solved this problem。 First，you should copy Operator module to mxnet。 Second , please do not run git checkoutand git submodule update in mxnet source code. If you want to know more details about this issue,please see here.

hi, I see the first line of the log. It means that your mxnet is not the required version that the author used. You need to delete the official mxnet: rm -rf /usr/local/lib/python2.7/dist-packages/mxnet, then compile mxnet reference @qixuxiang
