nki.language.var#

nki.language.var(x, axis, dtype=None, keepdims=False)[source]#

Variance along the specified axis (or axes) of the input.

((Similar to numpy.var))

Warning

This API is experimental and may change in future releases.

Parameters:

  • x – a tile.

  • axis – int or tuple/list of ints. The axis (or axes) along which to operate; must be free dimensions, not partition dimension (0); can only be the last contiguous dim(s) of the tile: [1], [1,2], [1,2,3], [1,2,3,4].

  • dtype – (optional) data type to cast the output type to (see Supported Data Types for more information); if not specified, it will default to be the same as the data type of the input tile.

  • keepdims – currently ignored; result always has keepdims=True shape.

Returns:

a tile with the variance of the elements along the provided axis.
