# torch.isfinite¶

torch.isfinite()

Returns a new tensor with boolean elements representing if each element is finite or not.

Real values are finite when they are not NaN, negative infinity, or infinity. Complex values are finite when both their real and imaginary parts are finite.

Arguments:

tensor (Tensor): A tensor to check

Returns:

Tensor: A torch.Tensor with dtype torch.bool containing a True at each location of finite elements and False otherwise

Example:

>>> torch.isfinite(torch.tensor([1, float('inf'), 2, float('-inf'), float('nan')]))
tensor([True,  False,  True,  False,  False])
