Issues with pretraining the model in multiple GPU multiple nodes #16

Open silabrata opened 10 months ago

silabrata commented 10 months ago

I am trying to pretraining the model using the train_pubchem_light.py on multiple GPUs across multiple nodes. When I run the code (with some modification for LSF to SLURM). For a multinode mullgpu run I am getting the following log:

However, the training doe does not start and the code kind of hangs here, Although the code continues to run but fails to propagate and show the losses. Can someone help me out with why it is getting stuck. It seems that master address, nodes and gpus are getting detected properly.
