蓝色机器学习笔记本上的错误: DataFrame的真值不明确

Question

在使用他们的笔记本时，我在Azure上部署了一个机器学习模型，但我遇到了一个错误。为了实现Power集成，我将跟踪这个教程。

当执行此代码时：

import sklearn

from azureml.core import Workspace
from azureml.core import Model
from azureml.core.resource_configuration import ResourceConfiguration

ws = Workspace.from_config()
model = Model.register(workspace=ws,
                       model_name='POC',                # Name of the registered model in your workspace.
                       model_path='./final_model.pkl',  # Local file to upload and register as a model.
                       model_framework=Model.Framework.SCIKITLEARN,  # Framework used to create the model.
                       model_framework_version=sklearn.__version__,  # Version of scikit-learn used to create the model.
                       sample_input_dataset=X,
                       sample_output_dataset=y,
                       resource_configuration=ResourceConfiguration(cpu=2, memory_in_gb=4),
                       description='RandomForestClassifier.',
                       tags={'area': 'finance', 'type': 'classification'})

print('Name:', model.name)
print('Version:', model.version)

我遇到了以下错误：

ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

    593                                            sample_input_dataset=sample_input_dataset,
    594                                            sample_output_dataset=sample_output_dataset,
--> 595                                            resource_configuration=resource_configuration)
    596 
    597         return model

我的sample_input_dataset for X是我的Pandas DataFrame，My的sample_output_dataset是Pandas系列，我也尝试使用Numpy数组。

解决方案是在TabularDataset中转换X和y。

这样做的唯一方法是在AML工作区中注册数据并下载它。也许还有更聪明的方法。
