查看 Hugging Face Sagemaker 模型的训练误差指标

Question

我已经使用 Hugging Face 与 Amazon Sagemaker 的集成训练了一个模型 and their Hello World example。

我可以通过在训练模型上调用 training_job_analytics 轻松计算和查看在评估测试集上生成的指标：准确性、f 分数、精确度、召回率等：huggingface_estimator.training_job_analytics.dataframe()

我怎样才能在训练集上看到相同的指标（甚至每个时期的训练误差）？

训练代码与 link 基本相同，添加了额外的文档部分：

from sagemaker.huggingface import HuggingFace

# optionally parse logs for key metrics
# from the docs: https://huggingface.co/docs/sagemaker/train#sagemaker-metrics
metric_definitions = [
    {'Name': 'loss', 'Regex': "'loss': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'learning_rate', 'Regex': "'learning_rate': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'eval_loss', 'Regex': "'eval_loss': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'eval_accuracy', 'Regex': "'eval_accuracy': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'eval_f1', 'Regex': "'eval_f1': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'eval_precision', 'Regex': "'eval_precision': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'eval_recall', 'Regex': "'eval_recall': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'eval_runtime', 'Regex': "'eval_runtime': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'eval_samples_per_second', 'Regex': "'eval_samples_per_second': ([0-9]+(.|e\-)[0-9]+),?"},
    {'Name': 'epoch', 'Regex': "'epoch': ([0-9]+(.|e\-)[0-9]+),?"}
]

# hyperparameters, which are passed into the training job
hyperparameters={
    'epochs': 5,
    'train_batch_size': batch_size,
    'model_name': model_checkpoint,
    'task': task,
}

# init the model (but not yet trained)
huggingface_estimator = HuggingFace(
    entry_point='train.py',
    source_dir='./scripts',
    instance_type='ml.p3.2xlarge',
    instance_count=1,
    role=role,
    transformers_version='4.6',
    pytorch_version='1.7',
    py_version='py36',
    hyperparameters = hyperparameters,
    metric_definitions=metric_definitions
)
# starting the train job with our uploaded datasets as input
huggingface_estimator.fit({'train': training_input_path, 'test': test_input_path})

# does not return metrics on training - only on eval!
huggingface_estimator.training_job_analytics.dataframe()

Answer 1

这可以通过将训练中的轮数增加到更现实的值来解决。

目前，模型的训练时间不到 300 秒（这是记录以下时间戳的时间），大概是损失函数。

要进行的更改：

hyperparameters={
    'epochs': 100, # increase the number of epochs to realistic value!
    'train_batch_size': batch_size,
    'model_name': model_checkpoint,
    'task': task,
}
