Mini-Lightning

Introduction

1. Mini-Lightning is a lightweight machine learning training library, which is a mini version of Pytorch-Lightning with only 1k lines of code. It has the advantages of faster, more concise and more flexible.
2. Existing features: support for DDP(multi-node and multi-gpu), Sync-BN, DP, MP(model parallelism), AMP, gradient accumulation, warmup and lr_scheduler, grad clip, tensorboard, huggingface, peft, LLM, torchmetrics, model and result saving, beautiful console log, etc.
3. Only the minimal interfaces are exposed, keeping the features of simplicity, easy to read, use and extend.
4. examples can be found in examples/
5. If you have any problems or bug finding, please raise issue, Thank you.

Installation

1. Create a virtual environment and install Python (>= 3.8)
2. Download the latest version (>=1.12) of Torch(corresponding CUDA version) from the official website of PyTorch.
3. Install mini-lightning

# from pypi
pip install mini-lightning -U

# Or download the files from the repository to local,
# and go to the folder where setup.py is located, and run the following command
# (Recommended) You can enjoy the latest features and functions (including bug fixes)
pip install -e .  # -e: editable mode
