From 04ac0607e913ab91234dfb240e12a76509e30982 Mon Sep 17 00:00:00 2001 From: crasm Date: Fri, 29 Dec 2023 09:50:29 -0500 Subject: [PATCH] python : add check-requirements.sh and GitHub workflow (#4585) * python: add check-requirements.sh and GitHub workflow This script and workflow forces package versions to remain compatible across all convert*.py scripts, while allowing secondary convert scripts to import dependencies not wanted in convert.py. * Move requirements into ./requirements * Fail on "==" being used for package requirements (but can be suppressed) * Enforce "compatible release" syntax instead of == * Update workflow * Add upper version bound for transformers and protobuf * improve check-requirements.sh * small syntax change * don't remove venvs if nocleanup is passed * See if this fixes docker workflow * Move check-requirements.sh into ./scripts/ --------- Co-authored-by: Jared Van Bortel --- .devops/full-cuda.Dockerfile | 3 +- .devops/full-rocm.Dockerfile | 3 +- .devops/full.Dockerfile | 3 +- .devops/main-rocm.Dockerfile | 3 +- .../workflows/python-check-requirements.yml | 29 +++ convert-hf-to-gguf.py | 95 ++++----- convert-lora-to-ggml.py | 183 +++++++++--------- convert-persimmon-to-gguf.py | 1 + requirements-hf-to-gguf.txt | 3 -
