TPU Is Detected but Not Used for Training#5

Description

opened on Aug 23, 2026

The system appears to detect the available TPU, but the training process does not actually use the TPU for computation.

Expected behavior

When a TPU is detected, the training pipeline should be able to initialize and use it for supported training workloads.

Suggested improvements
Properly initialize the detected TPU.
Ensure training operations are actually executed on the TPU.
Automatically configure the required TPU settings.
Provide a clear error or warning if the detected TPU cannot be used.
Verify TPU utilization during training.

The goal is to make TPU detection functional rather than detection-only, allowing users to actually take advantage of available TPU hardware.

                              The system appears to detect the available TPU, but the training process does not actually use the TPU for computation.
                              Expected behavior
                              When a TPU is detected, the training pipeline should be able to initialize and use it for supported training workloads.
                              Suggested improvements
                              
Properly initialize the detected TPU.
                              
Ensure training operations are actually executed on the TPU.
                              
Automatically configure the required TPU settings.
                              
Provide a clear error or warning if the detected TPU cannot be used.
                              
Verify TPU utilization during training.
                              The goal is to make TPU detection functional rather than detection-only, allowing users to actually take advantage of available TPU hardware.
