如何使用Anaconda安装特定版本的Python? [英] How to install the specific version of Python with Anaconda?

问题描述

我想用Python版本3.6.5安装Anaconda.如果我安装Anaconda3-5.2.0，则安装Python 3.5.1.在哪里下载带有Python 3.6.5的Anaconda.大数据脚本仅适用于Anaconda Python 3.6.5.

解决方案

Anaconda下载

使用Python 3.6.5的Anaconda发行版是版本5.2.0 . ¹ 您可以从 Miniconda .一旦工作正常...

创建您的Anaconda env:

conda create --name my_env python=3.6.5 anaconda=5.2.0

使用新的隔离环境:

conda activate my_env

_{[1] 我是通过运行conda create -n foo --dry-run -c anaconda python=3.6.5 anaconda然后检查Conda在解决方案中最终使用的anaconda软件包的版本来确定的.}

I want to install Anaconda with Python Version 3.6.5. If I install Anaconda3-5.2.0, It install Python 3.5.1. Where to download the Anaconda with Python 3.6.5. The Big Data Scripts work only with Anaconda Python 3.6.5.

解决方案

Anaconda Downloads

The Anaconda distribution with Python 3.6.5 was version 5.2.0.¹ You can download this from the Anaconda distribution archive. If you do install from this, then make sure to update Conda immediately after installation:

conda update conda

However, I strongly recommend the following alternate solution as better practice.

Miniconda + Anaconda env

Reasoning

What is installed in the base env is relatively fixed once you've installed it. Ultimately, you don't want to mess with your base environment, so best practice is to have the latest version there. Fortunately, you don't have to install a full Anaconda distribution, but rather can use the lightweight Miniconda distribution and create a secondary env for the purpose of having an Anaconda Python 3.6.5 distribution. In the long run this will give you better stability.

Steps

1. Download and install Miniconda. Once that is working...

2. Create your Anaconda env:

   conda create --name my_env python=3.6.5 anaconda=5.2.0
   

3. Use your new isolated env:

   conda activate my_env

_{[1] I determined this by running conda create -n foo --dry-run -c anaconda python=3.6.5 anaconda and then examining the version of the anaconda package that Conda ended up with in the solve.}
