以下问题是针对：
“Warning:This Python interpreter is in a conda environment, but the environment has not been activated. Libraries may fail to load. To activate this environment please see https://conda.
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.
“WARNING: The conda.compat module is deprecated and will be removed in a future release.”
1.我自己是之前安装了Python3.5的版本，又通过Anaconda安装了python2.7的版本，通过：复制一份Anaconda目录下的python.exe的副本在该目录中，并改名为python2.exe；Python35目录下的python.exe同理，复制一份，改为python3.exe，实现cmd或者bash中，python2指令打开python2.7，python3指令打开python3.5
2.上述操作基本完成了两个版本的python的调用，但是可能是因为python2.7是Anaconda附带的，所以需要在Anaconda目录下运行cmd，通过python2才能打开python2.7
3.python虽然可以打开，但是有Warning:
This Python interpreter is in a conda environment, but the environment has
not been activated. Libraries may fail to load. To activate this environment
please see https://conda.io/activation
按照网上其他的经验贴，conda activate myenv 或者：1.conda info --envs 然后 conda activate C:\Users\X_S\Anaconda2 （这是我自己的目录），依旧报错
CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.
4.最后在https://github.com/conda/conda/issues/8412 conda的github的issue里面找了解决办法
指令是 activate base ps：界面和cmd稍有不同，因为我用了cmder（基本和cmd一样，界面好看一点），不过不影响
5.可以发现还是有一个Waring，“WARNING: The conda.compat module is deprecated and will be removed in a future release.”
这个是conda 4.6.11的一个bug ，conda update conda 指令，更新一下conda就没了
