Hello,

I’m trying to replace the value of a tensor `x`

when the value in `x`

and the corresponding (i.e. at the same index) value in `y`

are both zeros.

Being `r`

the value I want to use for the substitution, I want to achieve something logically equivalent to: `if x_i==0 and y_i == 0 then x_i = r`

.

I tried with something like `x[x== 0 and y == 0] = r`

but it is not working.

What is the cleanest way to do this?

Thank you
