tensorflow: Installation Issue: Couldn't open CUDA library libcuda.so.1.

In the step where I have to run bazel-bin/tensorflow/cc/tutorials_example_trainer --use_gpu I get the following messages: I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcublas.so.7.0 locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcudnn.so locally I tensorflow/stream_executor/dso_loader.cc:108] successfully opened CUDA library libcufft.so.7.0 locally I tensorflow/stream_executor/dso_loader.cc:102] Couldn’t open CUDA library libcuda.so.1.

P.S. I have two GPUs installed on my server. One is used for GUI (AMD) and the other is used for computation (NVIDIA). Should I do anything to make sure the second GPU is being used?
