CUDA 12.3 and Python 3.9, with any TF, GPU not found

Is there a way to get the GPU’s to work? Python 3.11 works flawlessly. This is on RHEL 9.

Hi @RtheK, I was able to detect gpu with tensorflow 2.16-nightly.

Could please let us know in which environment you are facing an issue. Also i can see that you are using CUDA 12.3. could you please try by using CUDA 12.2. Thank You.

RHEL 9, Python 3.9, cudnn 12.9, and just upgraded CUDA to 12.4. Oddly, I have 2 GPU nodes that work just fine. The fix was to set CUDNN_PATH and include CUDNN_PATH/lib to $LD_LIBRARY_PATH. This one node has the same packages, but clearly there is some difference that I can’t find:

python3 -c "import tensorflow as tf; print(tf.config.list_physical_devices('GPU'))"

Notice that the log:

is repeated twice. That indicates 2 devices, and indeed, there are2 GPU’s, there has to be an env variable I am missing.

Hi @RtheK, As per test build configuration Tensorflow 2.16.1 supports CuDnn 8.9 and CUDA 12.3 but you are trying with CUDA 12.4 which is incompatible with 2.16. Could you please try with CUDA 12.3. Thank You.

There is an open issue regarding GPU utilization here: TF 2.17.0 RC0 Fails to work with GPUs (and TF 2.16 too) · Issue #63362 · tensorflow/tensorflow · GitHub

The respective pull request (pending review) with revised instructions to pip install tensorflow[and-cuda] for linux users with CUDA-enabled GPUs: docs/site/en/install/pip.md at patch-1 · sgkouzias/docs · GitHub I hope it helps!
