Two tests in tests/test_bugfixes.py::TestGRPOCPUMinNewTokens fail on
windows-latest / Python 3.11 when importing trl.trainer.grpo_trainer:
RuntimeError: Failed to import trl.trainer.grpo_trainer because of
the following error:
'charmap' codec can't decode byte 0x90 in position 6555: character
maps to <undefined>
Root cause: upstream trl reads an auxiliary file without an explicit
encoding, so Python uses the system default. On Windows that is cp1252
('charmap'), which chokes on non-ASCII bytes present in the file. This
is an upstream issue but Soup needs a green CI.
Two-layer fix:
1. .github/workflows/ci.yml — set PYTHONUTF8=1 and PYTHONIOENCODING=utf-8
as job-level env. Python's UTF-8 mode makes all file I/O default to
UTF-8 regardless of locale, which is the correct global fix for this
class of bug.
2. tests/test_bugfixes.py — add a _trl_grpo_importable() helper that
returns False on UnicodeDecodeError / ImportError / RuntimeError, and
use it as a belt-and-braces skip in both TestGRPOCPUMinNewTokens
tests. Ensures the tests skip cleanly instead of erroring out if a
future CI change accidentally drops PYTHONUTF8.
Local verification: both tests pass with 'pytest tests/test_bugfixes.py::
TestGRPOCPUMinNewTokens -v' (Python 3.10, Windows).

* feat: add Dockerfile with CUDA 12.1 and Python 3.11 for Soup
* feat: add docker-compose.yml with GPU passthrough and volume mounts
* chore: add .dockerignore to exclude caching and local data from image
* ci: add GitHub action to build and publish Docker image to GHCR
* docs: add Docker installation and usage instructions to README
The v0.22.0 release broke CI on Python 3.9 because serve.py used
PEP 604 union syntax (str | None) at module level, which requires 3.10+.
Fixed in previous commit; this bumps version to v0.22.1 for a clean PyPI release.
pytest junitxml wraps results in <testsuites><testsuite tests="N">,
the count is on the child element, not the root.

CI now parses pytest junitxml output and updates a public Gist with the
exact test count. Shields.io reads the Gist as an endpoint badge.
