jupyter笔记本没有运行

Question

当我放入终端 py -m jupyter notebook 时出现此错误

Traceback (most recent call last):
  File "c:\users\dos\appdata\local\programs\python\python35-32\lib\runpy.py", line 193, in _run_module_as_main

这个错误的原因是什么？

Answer 1

另一种方法是将 jupyter-client 版本降低到 6.1.12

你可以这样做

pip3 install --upgrade jupyter-client==6.1.12

Answer 2

问题是您的 python 版本较低（即 3.5.4），您必须考虑升级您的 python 版本等于或高于 3.6。 这将解决您的问题，因为语法在此更高版本中有效，并且不会出现更多错误。
