[QUESTION] how to enable multi-gpu when calling the predict method

[cumtsunzhenxing]

The predict method is called by setting gpus=2, but only one gpu is used. model.predict(samples=samples,batch_size=2, gpus=2, devices=2, accelerator="gpu", strategy="ddp")

[Sleepyhead1111]

you need to specify clear device number like "devices=[1,2]"： model.predict(samples=samples,batch_size=2,_ gpus=2, devices=[1,2], accelerator="gpu", strategy="ddp") or don‘t pass the 'devices' like： model.predict(samples=samples,batch_size=2,_ gpus=2, accelerator="gpu", strategy="ddp")
