Key point
Hugging Face proposed a draft standard for the Transformers Model Integration Contract (MIC) to strengthen CI regression detection.
Details
- Hugging Face proposed a draft standard for the MIC, a suite of checks that verifies in CI whether Transformers models run without bugs in specific frameworks
- It detects PR-stage regressions by running reduced models (fixtures) on CPU; in a 5-month replay experiment, it detected 1 out of 5 actual regressions and missed 4
- Adding the 4 missed API calls to the contract allowed all 5 to be detected upon re-execution, though this is not evidence of the unknown bug detection rate
- Reduced models use weights 10 to 1,300 times smaller than the originals, and 383 of 786 Transformers model types (66%) passed the reduction and build process
- Currently, the MIC job in Transformers CI only reports failures and does not block PRs; a switch to blocking will be considered once measurements of the actual PR bug detection rate and false positive frequency are completed
- The tools and experiment records are published in the
transformers-micrepository under the Apache 2.0 license, and contract generation and fixture building are possible via thetmicCLI
