When I run https://github.com/PaddlePaddle/models/blob/develop/fluid/image_classification/se_resnext.py, I met an error:

Traceback (most recent call last):

The PaddlePaddle is installed by pip install paddlepaddle and the version is 0.11. It seems that it needs a new PaddlePaddle version.

Since models are used for end users, maybe we need to test our implement from the user's point of view.
