Fixes blocking issue #5569.
Proposes upgrading the
macOS_regular
CI job from Python 3.7 to 3.9, to try to fix CI errors possibly related toconda-forge
dropping support for Python 3.7.Is this a breaking change for producing release artifacts?
I don't think so. The only artifact build from this task is the shared library for macOS,
lib_lightgbm.dylib
.LightGBM/.ci/test.sh
Lines 259 to 261 in d8a6b88
And that shouldn't be affected by Python version, as we don't produce a shared library that links into any Python stuff.
