TypeError: argument of type 'azureml.dataprep.rslex.StreamInfo' is not iterable

首先使用 azureml-opendatasets==1.55.0 运行提供的 NycTlcYellow 复现，然后检查 azureml/opendatasets/dataaccess/_blob_accessor.py，尤其是 get_spark_dataframe 和 _get_relative_path。跟踪 target_paths 包含 StreamInfo 的原因，并比较 pandas 和 Spark 路径；当 to_spark_dataframe 在没有报告的 TypeError 的情况下完成时，即表示完成。

Hi, I encountered below error, I have azureml-opendatasets==1.55.0
