GPU usage

Tensorflow and VTK can’t tolerant Theano access GPU at the same time. Errors similar to bellow will appear.

F tensorflow/stream_executor/cuda/cuda_driver.cc:316] current context was not created by the StreamExecutor cuda_driver API: 0x40e0f10; a CUDA runtime call was likely performed without using a StreamExecutor context

 

The way that I used to get around is:

  1. Allocate Theano to another GPU or to CPU

https://github.com/tensorflow/tensorflow/issues/916

 

  1. Store data first before calling VTK.
