how to use GPU? which version of Python, cuda, keras, and Theano should I use

[HHUBRO]

I want to inference with the pre-trained model, which version of Python, cuda, keras, and Theano should I use. Besides, Do you use the system-level cuda or the cuda in the virtual environment？ I have tried with python=2.7， keras=1.1.0，cuda=10.0，theano=1.0.4，if I inference with GPU， the result obviouly wrong（show 阿as fig）， while correct with the cpu，how can I fix it？
