如何将交叉验证结果记录为 azureml 中的表格？

如何解决如何将交叉验证结果记录为 azureml 中的表格？

我最近开始使用 azureml 进行自动化实验并登录 Azure 机器学习工作室。

在实验中，我想将 gridsearchcv 的结果存储在表格中。

run.log_table(name='Gridsearch results',value=search.cv_results_)

根据documentation，value应该是字典。就我而言，它看起来像这个问题底部的字典。但是，我收到以下错误：

Value of type <class 'list'> is not supported,supported types include [[<class 'float'>,<class 'str'>,<class 'bool'>,<class 'nonetype'>,<class 'int'>]]

甚至使用

将其转换为类似于文档中给出的格式

run.log_table(name='Gridsearch results',value=pd.DataFrame(search.cv_results_).to_dict(orient="list"))

产生相同的错误。有什么想法吗？
