Fix QGIS 3/4 compatibility: extras for supy 2026.4.3#14
Open
Conversation
- Update supy from 2026.1.28rc1 to 2026.1.28 (proper release) - Add pyarrow<23 constraint: supy 2026.1.28 _load.py uses pandas str.contains with regex, which breaks with pyarrow 23 (pyarrow.compute.match_substring_regex removed) Temporary workaround — the incompatible code path is already removed on supy master, so this cap can be dropped when the next supy release is cut. Ref: UMEP-dev/SUEWS#1252
2 tasks
- Move supy pin to optional-dependencies: qgis3 (rc1/NumPy 1.x) vs qgis4 (release/NumPy 2.x) - Keep pyarrow<23 in common deps (no-op on QGIS 3, needed on QGIS 4) - Install: pip install umep-reqs[qgis3] or umep-reqs[qgis4] Ref: UMEP-dev/SUEWS#1252

How will version of qgis be detected in relation to version number of umep-reqs? Lets say I make a new version of umep-reqs (3.0). What is the new syntax for e.f. QGIS 3.44? |

Yes, the syntax is exactly right: |

So we should find out user version so that they install correct umep-reqs |

Done — UMEP-dev/UMEP#831 wires up the version detection in |
- Bump supy pins: 2026.4.3rc1 (QGIS 3) and 2026.4.3 (QGIS 4) - Remove temporary pyarrow<23 cap — the incompatible code path was refactored in supy 2026.4.3 (UMEP-dev/SUEWS#1252) Ref: UMEP-dev/SUEWS#1274

QGIS 3 and QGIS 4 both use Python 3.12, so PEP 508 environment markers cannot distinguish them. Instead, extras let the UMEP plugin select the right supy build based on the detected QGIS version:
