Question

我为Python 3安装了IPython 3，以便与Jupyterhub一起使用。

现在我可以使用带有Python2内核的笔记本，因为我创建了/usr/local/share/jupyter/kernels/python2/kernel.json

使用：

{
 "argv": ["python2", "-m", "IPython.kernel",
          "-f", "{connection_file}"],
 "display_name": "Python 2",
 "language": "python2"
}

现在我还想使用IPython.parallel，但是当我启动一个集群时，它会自动启动Python 3中的引擎，如何将其更改为Python 2？

我通过

解决了这个问题

sudo mkdir /etc/ipython/

sudo nano /etc/ipython/ipython_config.py

添加以下行：

    c = get_config()

    c.LocalControllerLauncher.controller_cmd = ['/usr/bin/python2', '-m', 'IPython.parallel.controller']
    c.LocalEngineLauncher.engine_cmd = ['/usr/bin/python2', '-m', 'IPython.parallel.engine']
    c.LocalEngineSetLauncher.engine_cmd = ['/usr/bin/python2', '-m', 'IPython.parallel.engine']

现在引擎应该以python2

开头

编辑Jupyter 1.0或IPython 4.0： 改为

c = get_config()

c.LocalControllerLauncher.controller_cmd = ['/usr/bin/python2', '-m', 'ipyparallel.controller']
c.LocalEngineLauncher.engine_cmd = ['/usr/bin/python2', '-m', 'ipyparallel.engine']
c.LocalEngineSetLauncher.engine_cmd = ['/usr/bin/python2', '-m', 'ipyparallel.engine']

并获取群集标签： sudo mkdir / etc / jupyter /

sudo nano /etc/jupyter/jupyter_notebook_config.py

添加：

c.NotebookApp.server_extensions.append('ipyparallel.nbextension')

将Python 3内核的IPython 3更改为集群的python2
