Also, another topic related to getting extra info from debug=True:
$ python -c 'import torch; print(torch.cuda.is_available(), torch.version.cuda)'
False 10.0.130

$ python -c 'import tensorflow as tf; print(tf.test.is_gpu_available())'
...
E tensorflow/stream_executor/cuda/cuda_driver.cc:318] failed call to cuInit: CUDA_ERROR_UNKNOWN: unknown error
...
False

I guess cuInit: CUDA_ERROR_UNKNOWN: unknown error means I have to restart the machine. Knowing this errors would help as well.
