Sagemaker 管道创建中的 ValidationException

Question

我是 Sagmaker 的新手。我在 sagemaker 中创建了一个管道，我在其中将纪元数初始化为管道参数。但是当我插入时，它会显示此错误。请检查以下代码以供参考。

epoch_count = ParameterInteger(name="EpochCount", default_value=1)
pipeline = Pipeline(
name=f"a_name",
parameters=[
    training_instance_type,
    training_instance_count,
    epoch_count,
    hugging_face_model_name,
    endpoint_instance_type,
    endpoint_instance_type_alternate,
],
steps=[step_train, step_register, step_deploy_lambda],
sagemaker_session=sagemaker_session,

)

错误 - ---

ClientError: An error occurred (ValidationException) when calling the CreatePipeline operation: Cannot assign property reference [Parameters.EpochCount] to argument of type [String]

Answer 1

我替换

epoch_count = ParameterInteger(name="EpochCount", default_value=1)

和

epoch_count = ParameterString(name="EpochCount", default_value="1")

并且有效。也许我们只能在 sagemaker notebook 的管道参数中使用整数。但是 epoch_count 正在 docker 容器中使用，这不是 Sagemaker 直接的东西，这是我的理解。
