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时，Jupyter 都会说过程失败，下面是错误消息。

我应该如何解决这个问题？

ERROR:snowflake.connector.converter:Failed to convert: field T: TIME::76493.000000000

你能检查 Python 连接器的版本吗？该错误表明 Python 连接器不支持 TIME 数据类型。从 v1.0.6 开始支持 TIME 数据类型。截至今天，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
