error：CUB segmented reduce errorinvalid device function

[GaHooooo]

thanks for your great job！ ！ ！ but i have some question ： when i train the modelnet40_cls , some error happen:

During handling of the above exception, another exception occurred:

when i set the batch_size=1,it doesn't cause the error,but the result is very bad i don't know how to fix it thanks for your reply

The problem might be caused by the tensorflow version you are using. We test the code in Tensorflow 1.12.
