        Optional copy method to create a copy of the data source for use with a new device.
        Parameters:
        zone - The NSZone on which to allocate.
        device - The device where the kernel which uses this data source will be used.

        A pointer to a copy of this data source. API-Since: 12.0

      • encodeWithCoder

        default void encodeWithCoder​(@NotNull
                             @NotNull NSCoder aCoder)

      • epsilon

        default float epsilon()
        An optional tiny number to use to maintain numerical stability. output_image = (input_image - mean[c]) * gamma[c] / sqrt(variance[c] + epsilon) + beta[c]; Defalt value if method unavailable: FLT_MIN

      • gamma

        @Nullable
