A. anaconda安装需不需要安装python

不用，安装anaconda的时候它会顺带帮你把python给安装了

B. python anaconda 怎么安装

Anaconda is a completely free Python distribution (including for commercial use and redistribution). It includes over 195 of the most popular Python packagesfor science, math, engineering, data analysis.
1、安装anaconda
之前什么都不需要安装，直接在官网下载anaconda，我下载的是Python2.7，32位的。

下载后的文件是：

直接双击安装，可以自己选定安装位置（这个你自己决定）。
安装完成后，我们可以看到：

安装完anaconda，就相当于安装了Python、IPython、集成开发环境Spyder、一些包等等。

C. anaconda怎么安装python的各种库

安装好了anaconda之后,
可以用python自带的pip安装: pip install packagename

也可以用anaconda提供的conda安装: conda install packagename

D. 怎么安装python包在anaconda中

笔者使用Sublime Text 3，安装和配置插件Anaconda步骤如下：
安装：
打开package control菜单，输入install或者直接点击install package命令菜单
在新窗口输入Anaconda并点击第一个备选项进行安装。
安装完成后会显示messages文档

配置:
点击Anaconda插件默认设置菜单，弹出设置文档
在大约90行的位置，我们修改一下Python主程序的位置路径。

E. anaconda是什么和python什么关系装了anaconda是不是就不用装pyhton了

是的，Anaconda是Python的一个发行版，里面内置了很多工具，不用单独安装，因为做了优化也免去了单独安装带来的一些麻烦。

Anaconda是一种Python语言的免费增值开源发行版，用于进行大规模数据处理、预测分析，和科学计算，致力于简化包的管理和部署。Anaconda使用软件包管理系统Conda进行包管理。

(5)python安装anaconda扩展阅读：

anaconda相比Python增加了那些内容：

1、Python(shell) ： 标准CPython。

2、Python(shell)： 相当于在命令窗口的命令提示符后输入ipython回车。pip install ipython安装的ipython用法一样。

3、Ipython QTConsole。

4、Python Notebook：直接点击打开，或者在命令提示符中输入ipython.exe notebook。

5、Jupyter QTConsole。

6、Jupyter Notebook：直接点击打开，或在终端中输入： jupyter notebook 以启动服务器；在浏览器中打开notebook页面地址“http://localhost:8888”。

Jupyter Notebook是一种 Web 应用，能让用户将说明文本、数学方程、代码和可视化内容全部组合到一个易于共享的文档中。

7、Spyder：直接点击打开IDE。最大优点就是模仿MATLAB的“工作空间”。

8、Anaconda Prompt ： 命令行终端。

9、支持其他IDE，如Pycharm。

F. 如何安装anaconda和python

How to set up your own anaconda in a scientific way?

python2, python3, R in conda

Introction

  • what is anaconda?

  • According to its own website, Anaconda is the leading open data science platform powered by Python. The open source version of Anaconda is a high performance distribution of Python and R and includes over 100 of the most popular Python, R and Scala packages for data science.

  • Or you can simply regard it as a manager of the packages of your programming languages.

  • why we want to use anaconda?

  • Convinient to manage packages

  • Jupyter notebook

  • object

  • Set up anaconda for a python and r user (linux)

  • I use py2 more often so I set it my default environment

    • Get started!

  • Click this link and download corresponding version of anaconda.

  • Type the following line in the terminal and the installation will be set up automatically

    ```bash Anaconda2-4.3.1-Linux-x86_64.sh``` .

    Do include the "bash" command even if you are not using the bash shell.

  • Add the following line to the .bashrc or .zshrc(if you are a zsh user).

    ```export PATH="/home/zijun/anaconda2/bin:$PATH"```

  • Create python3 environment in your conda.

    ```conda create -n py3 python=3.5 anaconda```

  • Create R environment in your conda.

    ```conda create -n r -c r r-essentials```

  • Install tck for R (enable install.packages() in R)

    ```source activate r
    conda install -c intel tcl=8.6.4```

  • Note1: if you want to remove environment you install:

    ```conda remove --name py3 --all```

  • Note2: switch different environment

    ```source activate r
    source deactivate r```

    • Some issues you may encounter ring the process

    Q: tcl not found

    install.packages('highfrequency')
    --- Please select a CRAN mirror for use in this session ---
    Error: .onLoad failed in loadNamespace() for 'tcltk', details:
    call: fun(libname, pkgname)
    error: Can't find a usable init.tcl in the following directories:
    /opt/anaconda1anaconda2anaconda3/lib/tcl8.5 ./lib/tcl8.5 ./lib/tcl8.5 ./library ./library ./tcl8.5.18/library ./tcl8.5.18/library

    A: Solution:

  • Just do the step 5 above to solve this problem.

  • Or add the following lines to the .bashrc or .zshrc

    ``` export TCL_LIBRARY="/home/zijun/anaconda2/lib/tcl8.5"
    export TK_LIBRARY="/home/zijun/anaconda2/lib/tk8.5" ```

  • Note1: tck is a package which supports install.packages() function and it is installed in the global environment if you use sudo apt-get install tcl8.5-dev tk8.5-dev and conda has no access to it.

  • Note2: packages will be installed in /home/zijun/anaconda/envs/r/lib/R/library using install.packages()

    • Q: How to install packages in R

    A: Since we set up the tcl, we can easily use install.packages() or remove.packages() to manage the R packages. However in this way, conda will lose control over r packages. Also you may find some suggestions using conda-build like this:

  • switch back to the root environment

  • type conda install conda-build in the terminal

  • Use conda skeleton cran and conda build to install packages (you may mind the dependency issue)

    • However this will not give you the control either. Moreover, there might be more issues about shitty sytax in R. So my suggestion is simply using install.packages() in R to install your packages.



G. 安装anaconda前需要卸载python么

不用, anaconda(巨蟒)是python(蟒蛇)的集成版本, 集成了很多python包, 二者不冲突, 可以同时安装, 也可以切换着使用

H. 怎么在mac 系统上使用Python怎么安装Anaconda

在mac上搭建python环境：
mac系统其实自带了一个python的执行执行环境，用来运行python还行，但是开发可能就不够了，因此我们需要重新安装python。这里有两种方案安装：
1.homebrew
brew install python
这个方案比较简单,如果出错的话可以给前面加sudo试试,这个安装的python可能不是最新版.
2.从官网下载安装
大家可以从python官网下载安装最新版的python,安装比较无脑,一路按下去就OK,缺点是以后升级,卸载都得自己维护.
这两个方法安装的python的位置是不一样的,大家可以用:
which python
来查看安装位置.安装完成后在终端中键入python来验证安装是否成功.

安装Anaconda：
安装很简单，Anaconda Install就可以自动联网安装了。
