具有Python 2和Python3内核的Jupyter笔记本

Question

我想从Jupiter Notebook运行Python2以及Python3内核。我正在将Anaconda用于Python和Jupyter分发。

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ conda --version
conda 4.5.12

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ which python
/anaconda3/bin/python

Lokeshs-MacBook-Air-2:~ lokeshagrawal$ which jupyter notebook
/anaconda3/bin/jupyter

[![Lokeshs-MacBook-Air-2:~ lokeshagrawal$ python --version
Python 3.7.2

如下图所示，我只有一个选项可以从Jupyter启动Python3内核。我怎样才能同时拥有Python2和Python3？

Answer 1

1. 确保您的点子版本大于9.0

        2017 :{
            name: "Tony",
            age: 21,
            photo: "some url here"
          },
          {
            name: "Steve",
            age: 21,
            photo: "some url here"
          }
        2018 :{
            name: "Stark",
            age: 19,
            photo: "some url here"
          },
          {
            name: "Rogers",
            age: 21,
            photo: "some url here"
          }

1. 然后这样做

Sub CopyDataNEW()
    Dim sBook_t As Workbook
    Dim sBook_s As Workbook
    Dim wbPath_t As String
    Dim wbPath_s As String

    wbPath_t = "F:\TESt\DB_BA.xlsx"
    wbPath_s = "F:\TESt\PPC_BA.xlsm"

    Set sBook_s = Workbooks.Open(wbPath_s)
    Set sBook_t = Workbooks.Open(wbPath_t)

    sBook_s.Sheets("cstdata").Range("A2:EK2").Copy Destination:=sBook_t.Sheets("cstdatalist").Range("A2")
End Sub

1. 启动或重新启动Jupyter，您应该完成。

顺便说一下，此解决方案来自ipython docs。

Answer 2

您可以这样做：

conda create —name py2 python=2.7 anaconda 
conda activate py2
(py2) conda install ipykernel -y
(py2) python -m ipykernel install --user --name py2 --display-name "Python 2.7"

这将使用Python 2.7创建一个名为py2的环境，并将其添加到名称为Python 2.7的内核中。

如果我们要使用其他版本，例如同样，在Python 3.7中，我们可以执行相同的步骤：

conda update conda
conda create —name py3 python=3.7 anaconda 
conda activate py3
(py3) conda install ipykernel -y
(py3) python -m ipykernel install --user --name py3 --display-name "Python 3.7"

注意：您不必添加'anaconda'软件包。希望这可以帮助您了解如何在jupyter内核中添加环境。
