PyTorch on Azure ML: problem accessing GPU with ACPT environment image

Inizia da 20_image_build_log.txt intorno alla riga 3408 e da training_script.py intorno alla riga 22, quindi esamina la documentazione collegata relativa ad Azure ML ACPT e ai container GPU. Riproduci l’esecuzione usando l’immagine, le dimensioni del cluster e l’ambiente conda indicati e verifica che PyTorch venga importato correttamente e possa accedere alla GPU senza l’errore relativo al simbolo CUDA.

In Azure Machine Learning, I am trying to set up a PyTorch 2.0.1 run on a curated ACPT image:
mcr.microsoft.com/azureml/curated/acpt-pytorch-2.0-cuda11.7:latest
(based on this and this documentation)

I use the image above on a GPU cluster with size STANDARD_NC6and this conda environment yaml:

name: compass-environment-simple
channels:
  - anaconda
  - pytorch
  - nvidia
  - conda-forge
dependencies:
  - python==3.10.9
  - pip
  - pytorch==2.0.1
  - torchvision
  - torchaudio  
  - pytorch-cuda=11.7
  - cudatoolkit=11.7
  - pip:
      - pandas==2.0.1
      - numpy==1.24.3
      - azure-ai-ml==1.7.2
      - azureml-mlflow==1.51.0
      - mlflow==2.3.2
      - tensorboard==2.13.0
      - tensorboardX==2.6
      - matplotlib==3.7.1

      - xlwt==1.3.0
      - xlrd==2.0.1
      - XlsxWriter==3.1.0

But I keep getting a couple of error messages and I cannot access the GPUs when running the PyTorch Python scripts.

1. while building the image
   in 20_image_build_log.txt I get a warning that the NVIDIA driver can't be detected:
   WARNING: The NVIDIA Driver was not detected. GPU functionality will not be available.
   (see the attached 20_image_build_log.txt at line 3408)

2. when executing the Python script during a run
   I get the following error message:

/bin/bash: /azureml-envs/azureml_8536d86a92a3687bb89e1cff176aedf4/lib/libtinfo.so.6: no version information available (required by /bin/bash)

What am I doing wrong?
Thanks for your help.
