Training on single GPU works but Multiple GPUs throws an error #279

Open Saltb0xApps opened 10 months ago

Saltb0xApps commented 10 months ago

I have a lambda blade setup with 8x Nvidia Titan RTX GPUs.

Command for single GPU training - dora run solver=compression/debug

Output - Works ✅

My debug.yaml params -

dataset:
  batch_size: 64
  num_workers: 10
  segment_duration: 1
  train:
    num_samples: 200000
  valid:
    num_samples: 10000
  evaluate:
    batch_size: 32
    num_samples: 10000
  generate:
    batch_size: 32
    num_samples: 50
    segment_duration: 10

any ideas on what I can do to resolve this error and get multi-GPU training working? I believe I'm using a single node so I don't need to setup Slurm at all?

I tried running 

torchrun --master-addr NODE_1_ADDR --master-port MASTER_PORT --node_rank 0 --nnodes 2 --nproc-per-node 8 -m dora run [DORA RUN ARGS]

but it just gets stuck - how do I find the NODE_1_ADDR & MASTER_PORT values here?
