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
# inside ./safetensors/bindings/python
pip install .[dev]
Should be enough to install this library locally.
Testing
