DDP with shared file system

[YuShen1116]

Is it possible to use shared filesystem for DDP init_group in pytorch lighting? If so how what should I do to the Trainer?

Thanks!

I'm not quite sure about what you want to do, but if it's about customizing DDP, you can do the following:

from pytorch_lightning.plugins import DDPPlugin

class MyCustomDDP(DDPPlugin):
    ...

trainer = Trainer(plugins=[MyCustomDDP()])
