Hyperparameter tuning with Conversational AI Models #16878

ericharper · 2021-07-05T17:42:59Z

Hi,

We have multiple NeMo users that are interested in using Ray Tune with PyTorch Lightning. NeMo also uses PTL so it's a natural idea to leverage Ray Tune with NeMo: NVIDIA/NeMo#2442, NVIDIA/NeMo#2376

However, there is an issue with the model not being able to be pickled. Can Ray Tune + PTL be used with the large models that are used in Conversational AI?

Hey @ericharper, thanks for raising this up!

I just took a look at the issues, and it seems like there's two separate threads:

Distributed fine-tuning using Ray Lightning Plugins.
Distributed hyperparameter tuning using Ray Tune.

RE: distributed fine-tuning with Ray Lightning, it seems like there's some sort of serialization error for NeMo. Lightning requires the model to be instantiated before parallelization, and Ray will transfer the model through RPC, serializing it with cloudpickle. What's the fundamental reason for not being able to pickle? Is it some IO mechanism or underlying library?

RE: hyperparameter tuning, users should be able to use Ray Tune without running into the pickle problem. Specifically, we require users to instantiate the model in the function, so you would never need to move it around:

def train(hyperparameters):
   model = create_nemo_model(hyperparameters)
   return model.train()
   
ray.tune.run(train, resources={"GPU": 1})

I hope that gives a bit of clarity to answer your question! Happy to help out any way we can.

Thank you @ericharper for opening this!
@richard4912 I'm actually more interested in the Hyperparamter part from my side.
I've tried to do as suggested in this: https://docs.ray.io/en/master/tune/tutorials/tune-pytorch-lightning.html
The issue is that I get an error telling me that:

TypeError: can't pickle _thread.lock objects Other options: -Try reproducing the issue by calling pickle.dumps(trainable). -If the error is typing-related, try removing the type annotations and try again.

I tried to add the pickle.dumps(trainable) part but that did not work.
Thank you!

@Amels404 do you mind posting your stack trace and also your training function?

Thank you @richardliaw and @ericharper. My issue is related to BERT pretraining with ray_lightning and the BERTLMModel not being serializable apparently. I discussed this with @amogkam who suggested asking NeMo's team about it (#2376).

Amels404 · 2021-07-07T09:37:05Z

Yes sure, @richard4912

The cfg is a yaml file containing the parameters of the model.

`
@hydra_runner(config_path="configs", config_name=CONFIG_NAME)
def create_nemo_model(cfg):
logging.info(f"Hydra config: {OmegaConf.to_yaml(cfg)}")
callbacks = [
TuneReportCallback(
{"wer": "val_wer"}, on="validation_end"
)
]
trainer = pl.Trainer(**cfg.trainer,
callbacks=callbacks)
asr_model = EncDecCTCModel(cfg=cfg.model, trainer=trainer)
return trainer.fit(asr_model)

def train(config):
model = create_nemo_model(config)
return model.train()

config = {
"lr": tune.loguniform(1e-4, 1e-1),
"batch_size": tune.choice([32, 64, 128]),
}

ray.tune.run(train, config=config)
`

I'm sharing the trace using a better format.

Hmm, just to diagnose the issue, can you try commenting out hydra_runner?

# @hydra_runner(config_path="configs", config_name=CONFIG_NAME)
def create_nemo_model(cfg):
logging.info(f"Hydra config: {OmegaConf.to_yaml(cfg)}")
callbacks = [
TuneReportCallback(
{"wer": "val_wer"}, on="validation_end"
)
]
trainer = pl.Trainer(**cfg.trainer,
callbacks=callbacks)
asr_model = EncDecCTCModel(cfg=cfg.model, trainer=trainer)
return trainer.fit(asr_model)

def train(config):
model = create_nemo_model(config)
return model.train()

config = {
"lr": tune.loguniform(1e-4, 1e-1),
"batch_size": tune.choice([32, 64, 128]),
}

ray.tune.run(train, config=config)

richardliaw · 2021-07-12T02:05:16Z

The main issue is that there's something that is not serializable in create_nemo_model. I'm not sure what it is, but in order to fix that, you will either need to disable Tune's parallelism or convert the function to be serializable: see Cloudpickle for more details.

Amels404 · 2021-07-13T11:12:42Z

Thanks @richardliaw I've tried as you suggested, I think the issue was related to the logging part.
Then I got another issue "ray.tune.error.TuneError: Wrapped function ran until completion without reporting results or raising an exception"
I've tried to disable distributed training and I've tried to move reading the config file in outer function but that did not seem to resolve the issue.

Thank you!

OK, so this error comes up because hydra_runner seems to fail inside your training job.

Is the primary benefit of using Hydra to convert YAML -> a structured object? Hydra generally assumes it is a top level construct (i.e., put Tune inside the Hydra call).

Amels404 · 2021-07-15T09:51:35Z

Thank you for your reply,

I'm not sure if this is what you mean by put tune inside Hydra call, I think I'm missing something out because I have the same issue.

Hmm this one looks more promising to me. Can you post the stack trace? BTW, use three backticks to format your code: ```

@Amels404 what does hydra_runner do? Do you have the source code for that that you can share?

Amels404 · 2021-07-16T08:51:03Z

Yes, sure @richardliaw, we use hydra_runner from the nemo package that you can find here: https://github.com/NVIDIA/NeMo/blob/v1.0.0rc1/nemo/core/config/hydra_runner.py

and the imports in our file are like this:

from nemo.core.config import hydra_runner
from omegaconf import OmegaConf

richardliaw · 2021-07-17T17:38:44Z

OK thanks!

@hydra_runner(config_path="configs", config_name=CONFIG_NAME)
def import_conf(cfg):
    print(f"Hydra config: {OmegaConf.to_yaml(cfg)}") 
    a_yaml_file = open("/path/to/model.yaml")
    config = yaml.load(a_yaml_file, Loader=yaml.FullLoader)
    ray.tune.run(train, config=params)
    return cfg, config


params = {
"lr": tune.loguniform(1e-4, 1e-1),
"batch_size": tune.choice([1]),
}

Can you tell me more about what this does? I see you have a params dict along with a config dict; how do you want to merge these two?

richardliaw · 2021-07-17T17:43:51Z

Here's an attempt at getting you a bit farther:

# 
def create_nemo_model(cfg):
    logging.info(f"Hydra config: {OmegaConf.to_yaml(cfg)}")
    callbacks = [
        TuneReportCallback(
            {"wer": "val_wer"}, on="validation_end"
        )
    ]
    trainer = pl.Trainer(**cfg.trainer,
        callbacks=callbacks)
    asr_model = EncDecCTCModel(cfg=cfg.model, trainer=trainer)
    return trainer.fit(asr_model)

def train(config):
    model = create_nemo_model(config["hydraconfig"])
    return model.train()

@hydra_runner(config_path="configs", config_name=CONFIG_NAME)
def tune_function(cfg):
    # cfg is a omegaconf object?
    config = {
        "lr": tune.loguniform(1e-4, 1e-1),
        "batch_size": tune.choice([32, 64, 128]),
    }
    config["hydraconfig"] = cfg
    ray.tune.run(train, config=config)

Amels404 · 2021-07-26T10:49:27Z

@richardliaw I'm sorry for getting back to you late.

I think the issue that I have is: how to incorporate the ray config to the omega config file (precisely omegaconf.dictconfig.DictConfig), this is an example of the nemo config file:

https://github.com/NVIDIA/NeMo/tree/main/examples/asr/conf

I tried as you suggested but it doesn't seem to work, here is the trace:
```

thanks!

richardliaw · 2021-07-27T02:13:32Z

Awesome! I think we're close. It seems like we've overwritten Tune as a function.

Could you try:

def create_nemo_model(cfg):
    logging.info(f"Hydra config: {OmegaConf.to_yaml(cfg)}")
    callbacks = [
        TuneReportCallback(
            {"wer": "val_wer"}, on="validation_end"
        )
    ]
    trainer = pl.Trainer(**cfg.trainer,
        callbacks=callbacks)
    asr_model = EncDecCTCModel(cfg=cfg.model, trainer=trainer)
    return trainer.fit(asr_model)

def train(config):
    model = create_nemo_model(config["hydraconfig"])
    return model.train()

@hydra_runner(config_path="configs", config_name=CONFIG_NAME)
def tune_function(cfg):
    # cfg is a omegaconf object?
    config = {
        "lr": ray.tune.loguniform(1e-4, 1e-1),
        "batch_size": ray.tune.choice([32, 64, 128]),
    }
    config["hydraconfig"] = cfg
    ray.tune.run(train, config=config)

Amels404 · 2021-07-27T10:35:41Z

Yes, sure.
You can find also the print results of the vars and dir, I'm not sure if this might be useful.
Thanks!

Hey! I posted a new function to run in the previous message. Could you try that again?

Looks like great progress! We're quite close:

def create_nemo_model(cfg):
    logging.info(f"Hydra config: {OmegaConf.to_yaml(cfg)}")
    callbacks = [
        TuneReportCallback(
            {"wer": "val_wer"}, on="validation_end"
        )
    ]
    trainer = pl.Trainer(**cfg.trainer,
        callbacks=callbacks)
    asr_model = EncDecCTCModel(cfg=cfg.model, trainer=trainer)
    return trainer.fit(asr_model)

def train(config):
    model = create_nemo_model(config["hydraconfig"])
    return model.train()

@hydra_runner(config_path="configs", config_name=CONFIG_NAME)
def tune_function(cfg):
    # cfg is a omegaconf object?
    config = {
        "lr": ray.tune.loguniform(1e-4, 1e-1),
        "batch_size": ray.tune.choice([32, 64, 128]),
    }
    config["hydraconfig"] = cfg
    ray.tune.run(train, config=config, resources_per_trial={"gpu": 1})

try the above? Added a gpu line on the bottom.

It working now! I just needed to return the model instead of the model.train
Thank you very much!
