The NumberOfSamples parameter configured for the statistical instruction is invalid or incompatible with the size of the StorageArray or WeightArray. This condition prevents the averaging algorithm from executing and holds the Out value.
Click steps to track your progress.
Verify the value of the NumberOfSamples input parameter — ensure it is an integer between 1 and the minimum defined size of either StorageArray or WeightArray.
Check the declared sizes of StorageArray and WeightArray (if used) to ensure they are adequately dimensioned for the desired number of samples.
