Python科学计算的瑞士军刀——Anaconda 安装与配置

时间：2022-04-10 09:12:19

Introduce

Python是一种强大的编程语言，其提供了很多用于科学计算的模块，常见的包括numpy、scipy和matplotlib。要利用Python进行科学计算，就需要一一安装所需的模块，而这些模块可能又依赖于其它的软件包或库，因而安装和使用起来相对麻烦。幸好有人专门在做这一类事情，将科学计算所需要的模块都编译好，然后打包以发行版的形式供用户使用，Anaconda就是其中一个常用的科学计算发行版

自带的包管理器conda也很强大。

Getting Start

  1. 下载并安装Anaconda后，终端执行conda list可查看安装了哪些包

  2. 获取免费的学术License

    申请地址：https://store.continuum.io/cshop/academicanaconda 
    使用edu邮箱申请后，会在邮箱自动收到license_academic文件，将其放在~/.continuum目录下即可。

  3. 安装额外的包（命令行环境下执行）

    <code class="language-shell hljs ruby has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">$ </span>conda update conda
<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">$ </span>conda install accelerate
<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">$ </span>conda install iopro</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; opacity: 0.163836;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li></ul>

  4. 简单使用 
    编辑器中输入如下代码
