Use less time on the GPU runner in the CI - #465
Conversation
GitHub bills the GPU runner by the minute. Most of the work on it does not need a GPU, and some suites ran when they could not find a new failure. - Move the integration tests that do not train, tune or quantize a model to the new `cpu` suite. This suite also holds the unit tests, and it runs on a free runner. The tests that train have the new `gpu` marker and stay in the `misc` suite on the GPU runner. - Archive the model of the combinations test with one backbone only. The archive does not depend on the backbone, and its xz compression used two thirds of the time of the suite. - Add the `plan` job, which selects the test suites. When a pull request changes only the documentation, only the `cpu` suite runs. A draft pull request skips the `predefined_heavy` suite. When the pull request becomes ready for review, all the suites run. - Describe the suites and the `gpu` marker in CONTRIBUTING.md.

Since 2026-10-08, the RVC2 conversion job on HubAI fails and gives no error. The test is now in the `cpu` suite, which stops at the first failure, so this failure stops the suite and cancels the GPU suites. Mark the `rvc2` case of `test_convert_with_hubai` as an expected failure with `HubApiError`. Any other error still fails the test. The marker is not strict, so the CI does not fail when HubAI works again. Remove the marker then.
Two tests started to fail after 2026-10-07. The causes are outside this repository. - The RVC4 conversion on HubAI fails in the same way as the RVC2 conversion. Mark both cases of `test_convert_with_hubai` as expected failures with `HubApiError`. The marker is not strict. Remove it when HubAI works again. - LuxonisML added `resize_mode` to the NN Archive config. Add the value to the expected config of `test_custom_model`. The value is `LETTERBOX`, because `keep_aspect_ratio` is on by default.
When the `cpu` suite failed, fail-fast cancelled the GPU suites. They had already run for some minutes, and GitHub bills these minutes. Now the GPU suites wait for the `cpu` suite, so a failure that it finds costs no time on the GPU runner. The run takes about 15 minutes longer, because this is the time of the `cpu` suite. The `tests` job runs the `cpu` suite, and the new `gpu-tests` job runs the GPU suites. A YAML anchor gives the two jobs the same steps. The `plan` job now selects the GPU suites only. The names of the checks do not change.

A skipped matrix job shows its name without the expressions filled in.
When a change of the documentation only skips the GPU suites, the check
showed `tests (${{ matrix.suite }})`. Name the job `tests` instead.
GitHub adds the suite to the name of each matrix job, so the names of
the checks do not change.

AI-generated review comment The new Could we add |
Required checks stayed pending when path filters skipped documentation-only pull requests.
The archive test does not train and does not need the GPU runner.
HubAI conversion works again. The temporary xfail skipped conversion coverage.
Purpose
A full CI run used about 117 minutes on the T4 runner, and less than 10
of them to train models. This pull request moves the work that does not
need a GPU to
ubuntu-latest. It also runs the GPU suites only when theycan find a new failure.
Specification
cpusuite holds the unit tests and the integration teststhat do not train, tune or quantize a model. It runs on
ubuntu-latestand replaces theunitsuite.gpumarker identifies the tests that train, tune orquantize. They stay in the
miscsuite on the T4 runner. A testwithout the marker goes to the
cpusuite.cpusuite passes. Thetestsjob runs the
cpusuite, and the newgpu-testsjob runs the GPUsuites. A YAML anchor gives both jobs the same steps. The check names
do not change.
test_combinationsno longer archives the model for each backbone.The new
test_combinations_archivearchives it once, withEfficientRep. The backbone changes only the output shapes in the
archive, not the code that runs.
planjob selects the GPU suites:no coverage. This includes docstrings, comments, Markdown and the
settings of the linters and of the API docs.
