macOS、Metal、Comiler 遇到内部错误

问题描述

我现在尝试在使用 SwiftUI 和 BigSur、Xcode 12.3 的应用程序中使用 MPSImageErode 和 MPSImageDilate

代码

         let edSize = 9
         var erodedilateKernelValues:[Float] = [ 0.0,0.0,0.2,0.1,0.0]


         let dilateShader = MPSImageDilate(
            device: self.MetalDevice!,kernelWidth:edSize,kernelHeight:edSize,values:&erodedilateKernelValues)

         dilateShader.encode(commandBuffer: cmdBuf,sourceTexture: wipTexture!,destinationTexture: erodila)

         let erodeShader = MPSImageErode(
            device: self.MetalDevice!,values:&erodedilateKernelValues)
         
         erodeShader.encode(commandBuffer: cmdBuf,sourceTexture: erodila,destinationTexture: erodila2)

         cmdBuf.commit()
         cmdBuf.waitUntilCompleted()

         wipTexture = erodila2

结果

2021-01-02 19:33:40.320954+0900 XXX[5330:369599] /AppleInternal/buildroot/Library/Caches/com.apple.xbs/Sources/MetalPerformanceShaders/MetalPerformanceShaders-124.2.1/MPscore/Utility/MPSLibrary.mm,line 338: error 'MPSKernel MTLComputePipelinestateCache unable to load function DilateFilter4.

当我使用只有零的过滤器时，它确实有效

         var erodedilateKernelValues = [Float].init(repeating: 0.0,count: edSize * edSize)

但我想尝试不同的过滤器值，看看我是否可以改进对图像的分析。

有什么建议吗？
