Pixel Accuracy with Ignore

Problem

Compute pixel accuracy while ignoring pixels whose target equals ignore.

Return the fraction of the remaining pixels where pred equals target, rounded to 4 decimal places. Return 0.0 when every pixel is ignored.

case 1

in: [[[1,2],[3,4]],[[1,0],[3,-1]],-1]

expected: 0.6667

case 2

in: [[[0,0]],[[-1,-1]],-1]

expected: 0

case 3

in: [[[5,5],[5,5]],[[5,5],[5,5]],-1]

expected: 1
