Troubleshooting

PyTorch is not loading correctly in Tensorboard

This can be caused by running an old version of Tensorboard. Cancel the existing tensorboard job and resubmit with the latest version.

sbatch: error: Batch job submission failed: Requested node configuration is not available

For this workshop, make sure you are using the gpu partition with the reservation and the normal QoS.
