Summary:
This PR adds Azure Pipelines build steps for PyTorch. There are 3 pipelines that are added.
1) CI Build
- Runs when a PR is opened or when new commits to an open PR is added. This build must succeed before the PR can be merged.
- Currently only TestTorch unit tests are run.
- Only the CI Build configurations are run.
2) Daily Build
- Runs once a day during inactive hours to ensure the current PyTorch repo performs as expected.
- Runs all unit tests.
- Note: I do not have access to the current [determine-from](b9e900ee52/test/run_test.py (L737)) unit tests that are skipped on Windows builds. This `determine-from` filter can be added once a clear way to skip certain unit tests given the build configuration is explained.
- Runs on All Build configurations.
3) Official Build
- Runs once a day during inactive hours to publish official PyTorch artifacts to Azure DevOps Artifacts for consumption.
- No unit tests are run.
- Runs in three stages: Build, Verify, Publish, where PyTorch is built, then its wheel is installed in a clean Conda environment for verification, and then the wheel is published to Azure Artifacts as a Universal Package.
- Runs on All Build configurations.
Ubuntu builds run on Docker with the specified Dockerfile configuration. Windows builds run directly on configured Windows VMs (CPU, CUDA/cuDNN)
