CUDA 错误 - 语义分割答案

【问题标题】：CUDA Error - Semantic SegmentationCUDA 错误 - 语义分割

【问题描述】：

使用语义分割，我想将卫星图像分为两类：water 和land。我遇到了这个问题：

CUDA 执行期间发生意外错误。 CUDA 错误为：CUDA_ERROR_LAUNCH_FAILED

这是我的代码：

clear;clc;close all

dataDir = fullfile('C:\Users\firat\Desktop\TEZ\Uygulama\Semantic 
Segmentation\data');
imDir = fullfile(dataDir,'image');
pxDir = fullfile(dataDir,'imagePixelLabels');

imds = imageDatastore(imDir);

I = readimage(imds,1);
figure
imshow(I)

% imageLabeler(imDir);

classNames = ["Water" "Land"];
pixelLabelID = [1 2];
pxds = pixelLabelDatastore(pxDir,classNames,pixelLabelID);

C = readimage(pxds,1);

B = labeloverlay(I,C);
figure
imshow(B)

buildingMask = C == 'Water';
figure
imshowpair(I, buildingMask,'montage')

% Create a Semantic Segmentation Network

numFilters = 64;
filterSize = 3;
numClasses = 2;
layers = [
imageInputLayer([1024 1024 3])
convolution2dLayer(filterSize,numFilters,'Padding',1)
reluLayer()
maxPooling2dLayer(2,'Stride',2)
convolution2dLayer(filterSize,numFilters,'Padding',1)
reluLayer()
transposedConv2dLayer(4,numFilters,'Stride',2,'Cropping',1);
convolution2dLayer(1,numClasses);
softmaxLayer()
pixelClassificationLayer()
]

opts = trainingOptions('sgdm', ...
'InitialLearnRate', 1e-3, ...
'MaxEpochs', 100, ...
'MiniBatchSize', 64);

trainingData = pixelLabelImageSource(imds,pxds);

net = trainNetwork(trainingData,layers,opts);

testImage = imread('C:\Users\firat\Desktop\TEZ\Uygulama\Semantic 
Segmentation\test\test3.tif');

C = semanticseg(testImage,net);
B = labeloverlay(testImage,C);
figure
imshow(B)

我该如何解决这个问题？

看起来像是某种 CUDA 设置问题。什么是输出：
