MAC＋Anaconda安装MXNet

第一步：安装Anaconda

早期安装的是TensorFlow，使用的前置安装工具是Anaconda。总体感觉是：这个工具很好用！故Anaconda详细安装的步骤省略，这个不太费事。

第二步：安装MXNet

起因是从网络上搞到一本李沐大师参与编写的《动手学深度学习》，且更新时间为2019年4月，不可多得。于是，根据书中源码调试要求，想再安装MXNet框架，全面学习一下有关内容。

所以，自然想到使用Anaconda安装MXNet。现在完成安装后，总结来看——安装非常顺利；比较网络上的其他安装记录来看，更为简洁可取。现描述如下：

第1步：打开命令行，运行命令conda create -n mxnet

得到如下提示：

Collecting package metadata: done
Solving environment: done

## Package Plan ##

  environment location: /Users/zxzpc/anaconda3/envs/mxnet

Proceed ([y]/n)? y

按下回车，继续往下操作。接下来的提示如下：

Executing transaction: done
#
# To activate this environment, use
#
#     $ conda activate mxnet
#
# To deactivate an active environment, use
#
#     $ conda deactivate

第2步：激活mxnet环境

根据上面的提示，运行如下命令：

conda activate mxnet

正式安装MXNet

命令如下：

conda install mxnet

接下来的提示如下：

Collecting package metadata: done
Solving environment: done

## Package Plan ##

  environment location: ............./anaconda3/envs/mxnet

  added / updated specs:
    - mxnet

至此，MXNet安装结束。

第三步：在PyCharm下使用MXNet

这个只需要一步配置，打开PyCharm->Preferences，操作如下图所示：
