If installed from binary pip package, provide:

1. A link to the pip package you installed:
   export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.11.0-cp27-none-linux_x86_64.whl

2. The output from python -c "import tensorflow; print(tensorflow.__version__)".

If possible, provide a minimal reproducible example (We usually don't have time to read hundreds of lines of your code)

when trying to call a function that is only supported by cudnn, for example conv2d
