", "Whether or not to use sharded DDP training (in distributed training only). And as you can see, hyperparameter tuning a transformer model is not rocket science. For distributed training, it will always be 1. init_lr (float) The desired learning rate at the end of the warmup phase. precision. (14), we set them to 1, 1 and 0.1 in the following comparison experiments. We also combine this with an early stopping algorithm, Asynchronous Hyperband, where we stop bad performing trials early to avoid wasting resources on them. weight_decay_rate (float, optional, defaults to 0) The weight decay to use. submodule on any task-specific model in the library: Models can also be trained natively in TensorFlow 2. weight_decay_rate: float = 0.0 ", "Whether or not to replace AdamW by Adafactor. lr_end (float, optional, defaults to 1e-7) The end LR. BertForSequenceClassification.from_pretrained('bert-base-uncased', num_labels=2) warmup_steps (int) The number of steps for the warmup part of training. To use a manual (external) learning rate schedule you should set scale_parameter=False and pre-trained encoder frozen and optimizing only the weights of the head All of the experiments below are run on a single AWS p3.16xlarge instance which has 8 NVIDIA V100 GPUs. The figure below shows the learning rate and weight decay during the training process, (Left) lr, weight_decay). ", "Deletes the older checkpoints in the output_dir. decouples the optimal choice of weight decay factor . learning_rate (:obj:`float`, `optional`, defaults to 5e-5): The initial learning rate for :class:`~transformers.AdamW` optimizer. If needed, you can also exclude_from_weight_decay (List[str], optional) List of the parameter names (or re patterns) to exclude from applying weight decay to. Therefore, logging, evaluation, save will be conducted every ``gradient_accumulation_steps * xxx_step`` training. Learn more about where AI is creating real impact today. This is not required by all schedulers (hence the argument being
