The scripts in this directory are the entrypoint for testing Caffe2.
The environment variable BUILD_ENVIRONMENT is expected to be set to the build environment you intend to test. It is a hint for the build and test scripts to configure Caffe2 a certain way and include/exclude tests. Docker images, they equal the name of the image itself. For example: py2-cuda9.0-cudnn7-ubuntu16.04. The Docker images that are built on Jenkins and are used in triggered builds already have this environment variable set in their manifest. Also see ./docker/jenkins/*/Dockerfile and search for BUILD_ENVIRONMENT.
Our Jenkins installation is located at https://ci.pytorch.org/jenkins/.
