trl-setup SKILL.md skillA
trl-setup from cxcscmu/skilllearnbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cxcscmu/skilllearnbench/trl-setup@git:20260424.d50cf5aPins git:20260424.d50cf5a in mdr.lock. Pin the fingerprint instead.

Setup and installation of TRL (Transformer Reinforcement Learning) library with compatible torch/transformers versions. Use when setting up preference optimization training environments.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TRL Setup ## Installation ```bash pip install torch transformers trl accelerate peft datasets --break-system-packages ``` ## Compatibility Notes - TRL imports from `trl.trainer.utils`: `DPODataCollatorWithPadding`, `pad_to_length`, etc. - Some imports may change across TRL versions (e.g., `trl_sanitze_kwargs_for_tagging` vs `trl_sanitize_kwargs_for_tagging`) - If running in externally-managed Python (Debian), use `--break-system-packages` flag ## Common Import Errors - `trl_sanitze_kwargs_for_tagging` not found → check trl version, may be renamed or removed - Missing `CPOTrainer` → upgrade trl: `pip install --upgrade trl` ## Running Tests from Project Root ```bash cd /root/SimPO && python -m pytest unit_test/unit_test_1.py -v # or cd /root/SimPO && python unit_test/unit_test_1.py ``` ## Key TRL Trainer Utilities - `DPODataCollatorWithPadding`: handles padding for preference pairs - `pad_to_length`: pads tensor to specified length - `disable_dropout_in_model`: disables dropout during eval

How to install
mdr add cxcscmu/skilllearnbench/trl-setup@sha256:4072598100139cb8The line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
