1、启动jupyter-notebook启动缺少模块No module named 'ipyparallel'，具体：
Error loading server extension ipyparallel.nbextension
Traceback (most recent call last):
File "/usr/lib/python3.10/site-packages/notebook/notebookapp.py", line 2026, in init_server_extensions
mod = importlib.import_module(modulename)
File "/usr/lib/python3.10/importlib/__init__.py", line 126, in import_module
return _bootstrap._gcd_import(name[level:], package, level)
File "<frozen importlib._bootstrap>", line 1050, in _gcd_import
