当我们跑别人在github上的代码时，往往需要配置跟作者一样的环境。当作者导出自己的环境配置时，一般都是.yml文件，这时候需要输入命令行来实现配置一模一样的环境。
导出的yml文件一般配置如下：
name: vin_old_tf

- anaconda

- conda-forge
- defaults

prefix: /home/rubin/anaconda3/envs/vin_old_tf
如上述代码所示：name是创建虚拟环境之后在anaconda/envs文件夹下虚拟环境的名称，比如这个为：vin_old_tf；channels、dependents、pip都是需要下载的包名；prefix则是自己anaconda文件下虚拟环境的路径，
需要把这个路径改为自己的文件夹。
接下来配置和创建虚拟环境，输入如下命令行：
conda env create -f environment.yml然后按enter，系统就开始自动下载啦，等一段时间之后就安装和配置成功了。
PS：看安装成功与否可以看/home/rubin/anaconda3/envs/文件夹下有没有创建的虚拟环境的文件名，有的话就是安装成功了。
