無輸出-Jupyter Notebook

Question

首先，我將MacOSX與Chrome瀏覽器配合使用。

執行簡單的print語句時，我無法讀取任何輸出。

我首先創建一個名為“ hello.py”的簡單文件

print("hola")

然后我使用jupytext將其轉換為ipython筆記本格式

jupytext --to notebook hello.py

然后，我運行了jupyter notebook ，但是沒有任何輸出。

我嘗試了各種方法，例如“ 打印”未在ipython筆記本中顯示 。

根據其他地方的評論， *表示正在處理。 我給了它足夠的時間，它只是一個簡單的打印語句，應該立即處理。

可能有用的附加信息。 Pipfile

Answer 1

我可以通過卸載龍卷風6和安裝龍卷風5來解決此問題。

5.1.1是最后一個穩定版本，並解決了我的問題。
