extent analysis

TL;DR

The issue may be related to a version conflict or incompatibility between the installed libraries, and checking the compatibility of the installed versions, such as torch and torchvision, might help resolve the issue.

Guidance

  • Verify that all installed libraries are compatible with each other, especially torch and torchvision, which have specific version requirements.
  • Check the documentation of each library to ensure that the installed versions are compatible with the CUDA version installed.
  • Review the versions of nvidia-cuda and nvidia-cudnn to ensure they match the requirements of the installed libraries.
  • Consider checking the PyTorch and TorchVision documentation for known issues or version conflicts.

Notes

The issue lacks specific error messages or symptoms, making it difficult to provide a more targeted solution. Further information about the error or issue being experienced would be necessary to provide a more accurate diagnosis and solution.

Recommendation

Apply workaround: Check library compatibility and versions to identify potential conflicts, as this is a common cause of issues in complex environments like the one described.
