狗子家云端TPU运行时把Gemini逼疯了

Bro 想了半天

Locating Necessary Files

I am now focusing on updating the sine_mlp_tpu.py file. I will include the specific path you identified for the libtpu.so library within it. This should resolve the PJRT runtime’s inability to locate the necessary hardware driver, which was the cause of the error.

Updating Library Path

I have integrated the exact path for libtpu.so, located at ~/ml_env/lib/python3.10/site-packages/libtpu/libtpu.so, into the potential_lib_paths list within the sine_mlp_tpu.py file. The aim is to eliminate the initialization failure I was previously experiencing.

Configuring TPU Environment

I’ve set environment variables: TPU_LIBRARY_PATH and NEXT_PLUGGABLE_DEVICE_FOR_XLA with the found_lib path. The script now prints a success message confirming the TPU library location. If not found, a warning and troubleshooting prompt are provided. I’ve also incorporated the import statements for torch, torch.nn, torch.optim, math, torch_xla modules, and established the SineMLP model definition.

Implementing TPU Training Logic

I am now focusing on setting up the core TPU training loop within the script. I’ve defined train_tpu_core(index) to handle training on each TPU core, initializing the model and optimizer on the device. I’m configuring the training data, specifying an MSE loss function, and establishing the training parameters. I’ve also incorporated world size information and rank numbers for debugging and verification purposes. Finally, I’ve constructed the epoch loop and backpropagation step within the TPU environment.

Finalizing Training Script

I’ve integrated the final training output and diagnostic checks into the script. The script now prints the loss per epoch and confirms the completion of training. Crucially, I’ve incorporated TPU topology checks to ensure proper device detection and handles errors by attempting a fallback to a single-process mode, which may occur when max_workers fails to provide the expected number of devices. The script will either report the number of local TPU devices or provide a troubleshooting path.

Confirming Library Location

I’ve directly integrated os.path.expanduser("~") into the pathfinding logic. This ensures the script correctly locates libtpu.so within your ml_env directory, addressing the “No such file or directory” error. The script now prioritizes the specified location and attempts to override TPU_LIBRARY_PATH internally. The training should proceed smoothly now.
