Choose trl if…
- Requirements: TRL requires Python and is built on top of the Hugging Face Transformers library..
- Tags unique to trl: distributed training, huggingface, reinforcement learning, transformers.
- When you need to post-train language models or PEFT adapters on custom datasets with reinforcement learning.
When NOT to use trl
- If your project does not require reinforcement learning for training transformer models.
- When you do not need the specific distributed training methods supported by TRL.
- If you prefer a more general-purpose training library without the specialized reinforcement learning features.
Choose BMTrain if…
- Tags unique to BMTrain: apache-2.0 license, big model, fine-tuning, pre-training.
- BMTrain ships Docker support for self-hosted deployment.
- Need efficient pre-training or fine-tuning of large scale models
When NOT to use BMTrain
- Seeking a tool that installs without compiling C/CUDA source code
- Require immediate setup; BMTrain's installation might be time-consuming due to compilation steps
