python - TensorFlow 1.14.0 is not using GPU

Question

I set up TensorFlow using pip install --user tensorflow-gpu on my Ubuntu 19.04 laptop. All dependencies like CUDA, CUDNN are installed to and working. But still, when importing TensorFlow and checking tf.test.is_gpu_available() gives me False. I have tried completely uninstalling and reinstalling TensorFlow, which did not work. Output of tf.test.is_gpu_available():

Answer 1

My particular problem was that TensorFlow 1.14.0 were seeking for CUDA 10.0 binary, while I had only 10.1 installed. For some reason CUDA 10.0 could not be installed on my Ubuntu 19.04 so I installed 18.04 instead and followed standard way to make TF work with GPU (install CUDA 10.0, install CUDNN, etc.) and everything works just fine.

This table shows TF versions vs. required CUDA versions: https://www.tensorflow.org/install/source#linux

Here are instructions from TF: https://www.tensorflow.org/install/gpu#ubuntu_1804_cuda_10

You may also downgrade to TF 1.12 (CUDA 9.0): https://www.tensorflow.org/install/gpu#ubuntu_1604_cuda_90_for_tensorflow_1130
