pytorch实现多进程的时候出现的BUG：OMP: Error #13: Assertion failure at z_Linux_util.cpp(2361).

在跑强化学习A3C的代码时候，用到python和pytorch的多进程，但是遇到这样的bug。 

OMP: Error #13: Assertion failure at z_Linux_util.cpp(2361).                                                                                           │··································

首先，尝试了https://github.com/hszhao/semseg/issues/16 的方法，安装apex，之后发现并不起效果。

最后，找到了https://github.com/ContinuumIO/anaconda-issues/issues/11294，在python运行命令前面加上KMP_INIT_AT_FORK=FALSE，即可避免这个问题。
