Multi-GPU usage for Zeroshot/Finetune in Chronos2

[Claire-bx]

I am using Chronos2 for load forecasting and would like to leverage multiple GPUs (e.g., 4 GPUs) to accelerate zeroshot prediction and finetune training.
Are there any official examples or best practice guidelines for multi-GPU usage?
Thank you very much for your guidance!
