error in running imagenet_example_cw.py

[amirhamidihd]

I want to run imagene_example_cw.py, I haven't changed any thing in the source code, but I see this error:
AssertionError: The loss.shape should be (1L,), but the current loss.shape is (-1L, 1L). Maybe that you should call fluid.layers.mean to process the current loss.

what should I do?
Thanks.

Hi, @amirhamidihd
this problem caused, because your numpy version >=1.17, please use lower version, 1.16 and lower is ok. please try.
