⚠ In most cases you'll NEVER train a model on low-end SoC(s), this repo is mainly for CPU benchmark purpose. ;)

Installation

You can either install from PyPI:

# create venv (optional but recommended!!)
conda create -n xpi python==3.13    # py3.10 or later
conda create xpi
# install minimal version (torch, recommened!!)
pip install xpi-nn-train
# install full version (+lightning+peft)
pip install xpi-nn-train[full]

or install locally:

# create venv (optional but recommended!!)
conda create -n xpi python==3.13    # py3.10 or later
conda create xpi
# clone this repo
git clone https://gitee.com/kahsolt/xpi-nn-train.git
cd xpi-nn-train
# install dependencies
pip install -r requirements.txt
# install locally
pip install -e .

Usage

⚪ Use via API

Note that xpi-nn-train is opt for image classification benchmarking,

• for the basics, see tutorial.ipynb
• for other tasks please refer to espcn.ipynb

⚪ Use via command line

# run simple examples
python -m xpi_nn_train.examples.train_mnist -K torch -M MLP
python -m xpi_nn_train.examples.finetune_cifar10_mbv3 -K torch -F 1
# run LoRA finetune (need full version)
python -m xpi_nn_train.examples.train_mnist -K lightning -M LeNet
python -m xpi_nn_train.examples.train_mnist -K lightning -M LeNet -r 4 --load ./lightning_logs/version_1/checkpoints/epoch=4-step=2157.ckpt
# run ddp (hardcoded, temporarily only works on my machine 😈
python -m xpi_nn_train.examples.finetune_cifar10_mbv3_ddp
