Multi GPU training about daformer

[lhoyer]

Multi-GPU training is not supported by this repository. The variable n_gpus has no functionality and is only a relict, which I have forgotten to remove. You could refer to the original mmsegmentation framework if you want to integrate Multi-GPU training. However, you would also have to adapt the UDA procedure, which is not straightforward. Some potentially useful information is provided here: https://mmgeneration.readthedocs.io/en/latest/tutorials/ddp_train_gans.html

why not support Multi-GPU? is it not necessary for UDA?

Have you read code for SoftTeacher? This code seems to have nothing to do with ddp_train_gans, but it still use multi-gpu training UDA model.
