似乎以某种方式删除了我的一个内核。也许这就是我收到此错误的原因。我怎么可能修复它?我可以重新安装一些东西(也许是基础环境中的内核)?
如果没有更好的选择,我会尝试完全重新安装 anaconda 作为最后的手段
当前内核列表
jupyter kernelspec list
输出:
Available kernels:
python3 C:\Users\raysu\AppData\Roaming\jupyter\kernels\python3
vpython C:\ProgramData\jupyter\kernels\vpython
但是我必须有另一个与我的基本环境相关联的内核(我想它已经被删除了)。
C:\Users\raysu\Documents>conda env list
