mindspore.ops.coo_add

mindspore.ops.coo_add(x1: COOTensor, x2: COOTensor, thresh: Tensor)[source]

Computes the sum of x1(COOTensor) and x2(COOTensor), and return a new COOTensor based on the computed result and thresh.

Parameters

  • x1 (COOTensor) – the first COOTensor to sum.

  • x2 (COOTensor) – the second COOTensor to sum.

  • thresh (Tensor) – A 0-D Tensor, represents the magnitude threshold that determines if an output value/index pair take place. Its dtype should match that of the values if they are real. If output’s value is less than the thresh, it will vanish.

Returns

A COOTensor, the result of sum.

Raises

  • ValueError – If any input(x1/x2)’s indices’s dim is not equal to 2.

  • ValueError – If any input(x1/x2)’s values’s dim is not equal to 1.

  • ValueError – If any input(x1/x2)’s shape’s dim is not equal to 1.

  • ValueError – If thresh’s dim is not equal to 0.

  • TypeError – If any input(x1/x2)’s indices’s type is not equal to int64.

  • TypeError – If any input(x1/x2)’s shape’s type is not equal to int64.

  • ValueError – If any input(x1/x2)’s indices’s length is not equal to its values’s length.

  • TypeError – If any input(x1/x2)’s values’s type is not equal to anf of (int8/int16/int32/int64/float32/float64/complex64/complex128).

  • TypeError – If thresh’s type is not equal to anf of (int8/int16/int32/int64/float32/float64).

  • TypeError – If x1’s indices’s type is not equal to x2’s indices’s type.

  • TypeError – If x1’s values’s type is not equal to x2’s values’s type.

  • TypeError – If x1’s shape’s type is not equal to x2’s shape’s type.

  • TypeError – If (x1/x2)’s value’s type is not matched with thresh’s type.
