Jupyter 笔记本未启动 - AttributeError：模块“时间”没有属性“时钟”

Question

Traceback (most recent call last):
  File "c:\users\apu\appdata\local\programs\python\python38\lib\site-packages\IPython\utils\timing.py", line 27, in <module>
    import resource
ModuleNotFoundError: No module named 'resource'

在处理上述异常的过程中，又发生了一个异常：

Answer 1

看起来你的 IPython 包已经过时了，因为time.clock()几年前被弃用了，它的使用从 IPython 中删除了。 尝试升级您的 IPython： pip install --upgrade ipython并确保您运行的版本 >= 7.1.0（7.17.0 是最新版本）。
