python-pytorchHow do I save a PyTorch tensor to a file using Python?
To save a PyTorch tensor to a file using Python, use the following steps:
- Import the necessary libraries:
import torch import numpy as np
- Create a tensor object:
x = torch.tensor([1, 2, 3])
- Save the tensor to a file:
- Verify that the tensor has been saved correctly by loading it back into memory:
x2 = torch.load('x_tensor.pt') print(x2)
tensor([1, 2, 3])
- Save the tensor as a numpy array:
- Verify that the numpy array has been saved correctly by loading it back into memory:
x3 = np.load('x_tensor.npy') print(x3)
[1 2 3]
- Finally, you can also save the tensor to a text file:
torch.save(x, open('x_tensor.txt', 'w'))
