If set to None, the safetensors weights are downloaded if they’re available and if the
safetensors library is installed. If set to True, the model is forcibly loaded from safetensors
weights. If set to False, safetensors weights are not loaded.    Instantiate a pretrained PyTorch model from a pretrained model configuration. The model is set in evaluation mode - model.eval
