Thank you for the excellent Blogs!

When running https://github.com/philschmid/deep-learning-pytorch-huggingface/blob/main/training/instruction-tune-llama-2-int4.ipynb

I am trying to enable flash attention in a Sagemaker Notebook using ml.g5.2xlarge and nvidia-smi tells me I am on CUDA Version: 12.0 but 

os.environ["MAX_JOBS"] = "4" 
!pip install flash-attn --no-build-isolation

gives this error

      RuntimeError: FlashAttention is only supported on CUDA 11.6 and above.  Note: make sure nvcc has a supported version by running nvcc -V.

Is this something you've seen?

I am not sure if cuda 12.0 is yet supported. -> that's was the error says as well
