How to check if two Torch tensors or matrices are equal?

Question

I need a Torch command that checks if two tensors have the same content, and returns TRUE if they have the same content.

For example:

local tens_a = torc         


        

Answer 1

https://github.com/torch/torch7/blob/master/doc/maths.md#torcheqa-b

torch.eq(a, b)

Implements == operator comparing each element in a with b (if b is a number) or each element in a with corresponding element in b.

UPDATE

from @deltheil

torch.all(torch.eq(tens_a, tens_b))

or even simpler

torch.all(tens_a.eq(tens_b))
