Project description

Installation

pip install safetensors

Usage

Numpy

from safetensors.numpy import save_file, load_file
import numpy as np

tensors = {
   "a": np.zeros((2, 2)),
   "b": np.zeros((2, 3), dtype=np.uint8)
}

save_file(tensors, "./model.safetensors")


# Now loading
loaded = load_file("./model.safetensors")

Torch

from safetensors.torch import save_file, load_file
import torch

tensors = {
   "a": torch.zeros((2, 2)),
   "b": torch.zeros((2, 3), dtype=torch.uint8)
}

save_file(tensors, "./model.safetensors")


# Now loading
loaded = load_file("./model.safetensors")

Developing

pip install setuptools_rust
python setup.py develop

Should be enough to install this library locally.

Testing

pip install pytest   # We don't require pytest, but it's a common library used across HF.
pytest -sv tests/
