When running large models with FSDP, if we try to load full model params to each card we will run out of CPU RAM (refer to this these PRs huggingface/transformers#25107 huggingface/accelerate#1777.

Enabled CPU_RAM_EFFICIENT_LOADING configuration in accelerate to support above described functionality.
