今天使用pyg的jupyter环境发现这个环境没法用, 所以只能把这个kernel给重删了然后再装，操作记录如下
查看kernel
jupyter kernelspec list
注意不是jupyter kernel --list 需要加关键字spec,
删除kernel
jupyter kernelspec remove pyg
当重新安装这个kernel时可能会出错
python -m ipykernel install --name pyg
就出现了标题中的错误
File "/home/zhangjingxiao/.conda/envs/pyg/lib/python3.9/runpy.py", line 197, in _run_module_as_mainreturn _run_code(code, main_globals, None,File "/home/zhangjingxiao/.conda/envs/pyg/lib/python3.9/runpy.py", line 87, in _run_codeexec(code, run_globals)File "/home/zhangjingxiao/.local/lib/python3.9/site-packages/ipykernel/__main__.py", line 3, in <module>from ipykernel import kernelapp as appFile "/home/zhangjingxiao/.local/lib/python3.9/site-packages/ipykernel/kernelapp.py", line 21, in <module>from IPython.core.application import ( # type:ignore[attr-defined]File "/home/zhangjingxiao/.local/lib/python3.9/site-packages/IPython/__init__.py", line 54, in <module>from .terminal.embed import embedFile "/home/zhangjingxiao/.local/lib/python3.9/site-packages/IPython/terminal/embed.py", line 15, in <module>from IPython.core.interactiveshell import DummyMod, InteractiveShellFile "/home/zhangjingxiao/.local/lib/python3.9/site-packages/IPython/core/interactiveshell.py", line 140, in <module>from exceptiongroup import BaseExceptionGroup
ModuleNotFoundError: No module named 'exceptiongroup'
其实这个错误解决起来很简单的
pip install exceptiongroup
然后重新执行
注意要加上--user然后就可以了，
