How to perform oflloading in qlora? Compared to enable_sequential_cpu_offload, this method moves one whole model at a time to the GPU when its forward method is called, and the model remains in GPU until the next model runs. Fully sharded data parallel (FSDP) is developed for distributed training of large pretrained models up to 1T parameters. By sharding the model parameters, optimizer and gradient states, and even offloading them to the CPU when they’re inactive, FSDP can reduce the high cost of large-scale training. One of the advanced use case of this is being able to load a model and dispatch the weights between CPU and GPU. 21.
