Jupyter Notebook(Conda)中的python版本冲突 [英] Conflicting python version in jupyter notebook(Conda)

问题描述

我正在尝试使用Conda设置Jupyter笔记本，但是笔记本使用的python版本与Conda环境不同.

I am trying to setup Jupyter notebook using Conda, but the python version being used by notebook is not the same as the Conda environment.

我使用以下命令创建了"python_jupyter"环境.

I used the following command to create the 'python_jupyter' environment.

conda create -n python_jupyter python=3.6.5 ipykernel

但是在笔记本中，当我检查python版本时，根据检查方式的不同，会得到不同的结果.如果我使用bash命令进行检查，则可以获得预期的版本号3.6.5，但是从python代码中，可以获得3.6.3(我猜这是默认的Conda安装随附的默认版本).

But in the notebook, when I check the python version I get different results depending on how I am checking it. If I check using bash command I get the expected version number 3.6.5, but from python code, I get 3.6.3(which I am guessing the default one came with default Conda installation).

当我回到基本"(默认)环境时，版本冲突已解决，

When I go back to the 'base'(default) environment, the version conflict is resolved,

为什么第一张图片中存在python版本冲突，我该如何解决?

Why there is a python version conflict in the first image, and how do I resolve it?

当我在'python_jupyter'环境处于活动状态的命令行上运行'conda info'时，我看到python版本被报告为3.6.3.但是如果我运行"python -V"，我会看到python版本3.6.5.为什么会有这种差异?另外，当我尝试使用'conda update python'更新python时，它不会提示我进行更新，这意味着conda认为我使用的是最新的python版本3.6.5.

When I run 'conda info' on the command line with 'python_jupyter' environment active I see python version is being reported as 3.6.3. But if I run 'python -V' I see python version 3.6.5. Why this discrepancy? Also when I try to update python using 'conda update python' it doesn't prompt me for an update which means conda thinks I am on the latest python version 3.6.5.

推荐答案

问题是通过在python_jupyter环境中运行conda install ipython jupyter解决的.由于我能够使用默认安装运行jupyter notebook命令，因此我假设jupyter Notebook安装已完成.

The problem was solved by running conda install ipython jupyter on my python_jupyter environment. Since I were able to run jupyter notebook command with the default installation, I was under the assumption that jupyter notebook installation was complete.

conda info报告基本环境中的Python版本，conda list或conda list -f python或python -V报告当前活动环境中的Python版本，在本例中为python_jupyter. 来源

conda info reports the version of Python in the base environment, and conda list or conda list -f python or python -V reports the version of Python in the currently active environment, in this case python_jupyter. Source
