如何删除旧的 ipykernels

我正在摆弄linux并尝试使用环境。在这个实验期间，我创建了各种没有任何用途的内核。

source my_environment_name/bin/activate  
python -m pip install ipykernel          
python -m ipykernel install

python -m ipykernel install --user --name=test_venv

我正在尝试删除旧内核，但我不知道它们存储在哪里，而且我无法弄清楚如何使用终端来执行此操作。我天真地尝试过：

python -m ipykernel uninstall --user --name=test_venv

但这不起作用。如何通过删除旧内核来清理环境？

答案1

找到他们：

/home/solebay/.local/share/jupyter/kernels/env

答案2

使用jupyter kernelspec命令来管理你的内核：

$ jupyter kernelspec --help
Manage Jupyter kernel specifications.

Subcommands
-----------

Subcommands are launched as `jupyter kernelspec cmd [args]`. For information on
using subcommand 'cmd', do: `jupyter kernelspec cmd -h`.

list
    List installed kernel specifications.
install
    Install a kernel specification directory.
uninstall
    Alias for remove
remove
    Remove one or more Jupyter kernelspecs by name.
install-self
    [DEPRECATED] Install the IPython kernel spec directory for this Python.
provisioners
    List available provisioners for use in kernel specifications.

To see all available configurables, use `--help-all`

$ jupyter kernelspec list
Available kernels:
  ch701      /home/jovyan/.local/share/jupyter/kernels/ch701
  isis       /home/jovyan/.local/share/jupyter/kernels/isis
  python3    /opt/conda/envs/isis/share/jupyter/kernels/python3

$ jupyter kernelspec remove ch701
Kernel specs to remove:
  ch701                 /home/jovyan/.local/share/jupyter/kernels/ch701
Remove 1 kernel specs [y/N]: y
[RemoveKernelSpec] Removed /home/jovyan/.local/share/jupyter/kernels/ch701

$ jupyter kernelspec list
Available kernels:
  isis       /home/jovyan/.local/share/jupyter/kernels/isis
  python3    /opt/conda/envs/isis/share/jupyter/kernels/python3

瞧！
