Summary: A few Caffe2 tests are currently disabled in `py2-gcc4.8-ubuntu14.04` test job because they are known to be flaky. https://github.com/pytorch/pytorch/pull/13055 likely had fixed the flakiness, and this PR tests it. Fixes https://github.com/pytorch/pytorch/issues/12395. Pull Request resolved: https://github.com/pytorch/pytorch/pull/13356 Differential Revision: D12858206 Pulled By: yf225 fbshipit-source-id: 491c9c4a5c48ac1b791fdc9d78acf66091e80457
