在Jupyter中切换内核

Question

jupyter kernelspec list

Available kernels:
  **python3    /home/vijay/anaconda3/share/jupyter/kernels/python3
  python2    /usr/local/share/jupyter/kernels/python2**

我无法在Jupyter笔记本中将内核从python3切换到python 2。

在启动jupyter笔记本时，将显示以下命令

JupyterLab alpha preview extension loaded from /home/vijay/anaconda3/lib/python3.6/site-packages/jupyterlab**
JupyterLab v0.27.0
Known labextensions:
[I 10:51:15.216 NotebookApp] Running the core application with no additional extensions or settings
[I 10:51:15.255 NotebookApp] Serving notebooks from local directory: /home/vijay
[I 10:51:15.255 NotebookApp] 0 active kernels 

Answer 1

如果来自另一个conda环境的内核在Jupyter中不可见，请查看nb_conda_kernels包。 它找到现有的conda环境并动态地将ipython内核添加到Jupyter。
