python-pytorchHow do I convert a Python Torch tensor to a float?
To convert a Python Torch tensor to a float, use the item()
method. This returns the value of the tensor as a standard Python number. For example:
import torch
x = torch.tensor([3.14])
x_float = x.item()
print(x_float)
# Output: 3.14
The item()
method can be used on any tensor with one element, such as a scalar or a one-dimensional tensor. It will raise an error if the tensor has more than one element.
Code explanation
import torch
: Imports the torch module.x = torch.tensor([3.14])
: Creates a tensor containing the value 3.14.x_float = x.item()
: Calls theitem()
method on the tensor to convert it to a float.print(x_float)
: Prints the converted float.
