无输出-Jupyter Notebook

首先，我将MacOSX与Chrome浏览器配合使用。

执行简单的print语句时，我无法读取任何输出。

我从创建一个简单的文件“ hello.py”开始

print("hola")

然后我使用jupytext将其转换为ipython笔记本格式

jupytext --to notebook hello.py

然后jupyter notebook，我跑了，但是我没有收到任何输出。

我尝试了各种方法，例如“打印”未在ipython笔记本中显示。

根据其他地方的评论*，这表示它正在处理。我给了它足够的时间，它只是一个简单的打印语句，应该立即处理。

可能有用的附加信息。点文件
