Add fairscale.nn.misc.checkpoint_activations #376

WebActivation checkpointing is a technique used to reduce GPU memory usage during training. This is done by avoiding the need to store intermediate activation tensors during the forward pass. Instead, the forward pass is recomputed by keeping track of the original input during the backward pass. WebIn this case, you can use checkpoint_wrapper and offload the activation to cpu using that wrapper. This way, only during backward, the tensor will be moved back to gpu. Thanks for telling me the solution, I will dive into it in the future.

Efficient memory usage using Activation Checkpointing FairScale …

WebFairScale Activation Checkpointing¶ Activation checkpointing frees activations from memory as soon as they are not needed during the forward pass. They are then re-computed for the backwards pass as needed. Activation checkpointing is very useful when you have intermediate layers that produce large activations. WebActivation Checkpoint. A friendlier wrapper for performing activation checkpointing. To understand the benefits of checkpointing and the offload_to_cpu flag, let’s divide activations into 2 types: inner activations and outer activations w.r.t. the checkpointed …

WebMar 14, 2024 · FairScale FSDP was released in early 2024 as part of the FairScale library. And then we started the effort to upstream FairScale FSDP to PyTorch in PT 1.11, making it production-ready. We have selectively upstreamed and refactored key features from FairScale FSDP, redesigned user interfaces and made performance improvements. WebJul 27, 2024 · I'm testing activation checkpointing on FSDP models, to my surprise, PyTorch's native checkpoint_wrapper seems not working at all, not saving any memory whatsoever, I switched to fairscale's checkpoint_wrapper, huge memory has been saved.
