如何將時間列從雪花輸入到jupyter notebook數據框？

Question

我需要將數據從雪花導入Jupyter。在數據集中，我有一個從時間戳值派生的時間列。

每次我嘗試導入數據，Jupyter說，這個過程失敗，下面是錯誤消息。

我應該如何解決這個問題？

你可以檢查Python連接器版本嗎？該錯誤指示Python連接器不支持TIME數據類型。 TIME數據類型自v1.0.6開始支持。截至今天，最新的版本是1.2.8： https://pypi.python.org/pypi/snowflake-connector-python/

這裏是TIME數據類型的Jupyter筆記本爲例： https://gist.github.com/smtakeda/e401c80d71f2da4aa7452d238c5ccffa
