【问题描述】：
首先，我使用的是带有 chrome 浏览器的 MacOSX。
执行简单的打印语句时，我无法读取任何输出。
我首先创建了一个名为“hello.py”的简单文件
print("hola")
然后我使用 jupytext 将其转换为 ipython 笔记本格式
jupytext --to notebook hello.py
然后我运行jupyter notebook，但是我没有收到任何输出。
我试过Print not showing in ipython notebook等各种方法。
根据其他地方的评论，* 表示它正在处理中。我给了它充足的时间，它只是一个简单的打印语句，应该立即处理。
可能有用的其他信息。 点文件

我是 Jupyter 的新手，但是刚刚注意到 Python 3 旁边的图标，在注销按钮下方与我的不同。对我来说，它是一个圆形轮廓，表示内核处于空闲状态，当我运行代码（等待输出时）时，它变为阴影，表示内核处于忙碌状态。也许你应该检查那个图标的含义？
