A decorator for seamless PyTorch calculations (primarily on CUDA) from numpy.ndarray and pd.DataFrame.
Project description
Installation
$ pip install torch_fn
Usage
from torch_fn import torch_fn
import numpy as np
import torch.nn.functional as F
@torch_fn
def torch_softmax(*args, **kwargs):
return F.softmax(*args, **kwargs)
def custom_print(x):
print(type(x), x)
# Test the decorator with different input types
x = [1, 2, 3]
x_list = x
x_tensor = torch.tensor(x).float()
x_tensor_cuda = torch.tensor(x).float().cuda()
x_array = np.array(x)
x_df = pd.DataFrame({"col1": x})
custom_print(torch_softmax(x_list, dim=-1))
