How to use specified GPUs with Accelerator to train the model?

Thanks for you reply! I tried to use accelerate config, but I haven’t found a place to specify the gpu cards that I want to use. For example, if I set nproc_per_node to 4, it will automatically use gpu:0, gpu:1, gpu:2, gpu:3 on my machine. Is there a way to change this behavior?
Thank you so much~
