To reproduce

Hi, I am trying to do grid search on my roberta model.

Steps to reproduce the behavior:

  hyperParameters = {
    "per_gpu_batch_size": [32],
    "learning_rate": [2e-5],
    "num_epochs": [2,3]
  }
  

  def my_hp_space_ray(trial):
      from ray import tune
  
      return {
          "learning_rate": tune.choice(hyperParameters.get('learning_rate')),
          "num_train_epochs": tune.choice(hyperParameters.get('num_epochs'))
      }

training_args = TrainingArguments("test",
                                  per_device_train_batch_size= 32,
                                  per_device_eval_batch_size = 32,
                                  evaluation_strategy = "epoch", #Can be epoch or steps
                                  weight_decay=0.01,
                                  logging_strategy ="epoch",
                                  metric_for_best_model="accuracy",
                                  report_to="wandb"
                                  )

trainer = Trainer(
    args=training_args,
    tokenizer=tokenizer,
    train_dataset=tokenized_datasets_train,
    eval_dataset=tokenized_datasets_val,
    model_init=model_init,
    compute_metrics=compute_metrics,
)

trainer.hyperparameter_search(
    direction="minimize", 
    backend="ray",
    n_trials= 2,
    hp_space = my_hp_space_ray)

Expected behavior

Hi i would like to hyper parameter tune my roberta model, using ray tune and the trainer API, is there a way to not run out of memory even if it takes longer time to finish? Or is there some other type of parameter tuning i should use instead?

I spent the whole day trying to figure it out, so any help would be hugely appreciated

@Yard1 @richardliaw updating transformers did help. Huge thanks!

altho i have one last question, is there a way to specify to use tpu’s instead of gpu’s in the api?

At the moment i have it like this,

trainer.hyperparameter_search(
    direction="minimize", 
    backend="ray",
    n_trials= 1,
    hp_space = my_hp_space_ray,
    resources_per_trial =  {"cpu": 1,"gpu": 1},
    fail_fast="raise"
    )

Seems like the error is:

(pid=1376)   File "/usr/local/lib/python3.7/dist-packages/ray/tune/utils/trainable.py", line 344, in inner

as a tip, maybe you could consider also doing hyperparameter_search(..., fail_fast="raise") to help see errors better.
