如何将时间列从雪花输入到jupyter notebook数据框？

Question

我需要将数据从雪花导入Jupyter。在数据集中，我有一个从时间戳值派生的时间列。

每次我尝试导入数据，Jupyter说，这个过程失败，下面是错误消息。

我应该如何解决这个问题？

你可以检查Python连接器版本吗？该错误指示Python连接器不支持TIME数据类型。 TIME数据类型自v1.0.6开始支持。截至今天，最新的版本是1.2.8： https://pypi.python.org/pypi/snowflake-connector-python/

这里是TIME数据类型的Jupyter笔记本为例： https://gist.github.com/smtakeda/e401c80d71f2da4aa7452d238c5ccffa
