It may be a simple question. I downloaded the tarball from github releases page, however the  tarball doesn’t work. How to make it work ?
(eee) [ pytorch-0.4.1]$ python setup.py  install
fatal: not a git repository (or any of the parent directories): .git
running install
running build_deps
Could not find /home/liangstein/test_tarballs/4.1/pytorch-0.4.1/third_party/gloo/CMakeLists.txt
Did you run ‘git submodule update --init’?
(eee) [ pytorch-0.4.1]$ git submodule update --init
