Shard pytorch
WebbIf OSS is used with DDP, then the normal PyTorch GradScaler can be used, nothing needs to be changed. If OSS is used with ShardedDDP (to get the gradient sharding), then a very similar flow can be used, but it requires a shard-aware GradScaler, which is available in fairscale.optim.grad_scaler. Webbför 2 dagar sedan · I'm dealing with multiple datasets training using pytorch_lightning. Datasets have different lengths ---> different number of batches in corresponding DataLoader s. For now I tried to keep things separately by using dictionaries, as my ultimate goal is weighting the loss function according to a specific dataset: def …

In practice, this means we can remain at parity with PyTorch DDP, whilst scaling our model sizes dramatically. The technique is similar to ZeRO-Stage 3.
