Question

我需要将数据从雪花导入Jupyter。在数据集中，我有一个时间列，它是从时间戳值导出的。

每次我尝试导入数据时，Jupyter都说过程失败了，下面是错误信息。

我该如何解决这个问题？

您可以查看Python Connector版本吗？该错误表示Python Connector不支持TIME数据类型。自v1.0.6起支持TIME数据类型。截至今日，最新版本为1.2.8： https://pypi.python.org/pypi/snowflake-connector-python/

以下是Jupyter笔记本中TIME数据类型的示例： https://gist.github.com/smtakeda/e401c80d71f2da4aa7452d238c5ccffa

如何从雪花到jupyter笔记本数据框导入时间列？
