Webweight_decay ( float, optional) – weight decay (L2 penalty) (default: 0) foreach ( bool, optional) – whether foreach implementation of optimizer is used. If unspecified by the user (so foreach is None), we will try to use foreach over the for-loop implementation on CUDA, since it is usually significantly more performant. (default: None)
