nki.language.add#

nki.language.add(x, y, dtype=None)[source]#

Add the inputs, element-wise.

((Similar to numpy.add))

Warning

This API is experimental and may change in future releases.

Parameters:

  • x – a tile or a scalar value.

  • y – a tile or a scalar value.

  • dtype – (optional) data type to cast the output type to (see Supported Data Types for more information);

Returns:

a tile that has x + y, element-wise.

Examples:

import nki.language as nl

# nki.language.add -- element-wise addition of two tiles
a = nl.full((128, 512), 3.0, dtype=nl.float32, buffer=nl.sbuf)
b = nl.full((128, 512), 2.0, dtype=nl.float32, buffer=nl.sbuf)
c = nl.add(a, b)

expected = nl.full((128, 512), 5.0, dtype=nl.float32, buffer=nl.sbuf)
assert nl.equal(c, expected)

# nki.language.add -- adding a scalar to every element of a tile
a = nl.full((128, 512), 3.0, dtype=nl.float32, buffer=nl.sbuf)
c = nl.add(a, 2.0)
expected = nl.full((128, 512), 5.0, dtype=nl.float32, buffer=nl.sbuf)
assert nl.equal(c, expected)
