This is a copy of the original
OPT weights that is more efficient to use with the
DeepSpeed-MII and
DeepSpeed-Inference. In this repo the original tensors are split into 8 shards to target 8 GPUs, this allows the user to run the model with DeepSpeed-inference Tensor Parallelism.
For specific details about the OPT model itself, please see the
original OPT model card.
