使用語義分割,我想將衛星圖像分爲兩類:waterland。我遇到此問題:CUDA錯誤 - 語義分割

CUDA執行期間發生意外錯誤。 CUDA的錯誤是:CUDA_ERROR_LAUNCH_FAILED

這裏是我的代碼:

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) 

我怎樣才能解決這個問題?

看起來像某種CUDA設置問題。什麼是輸出:

gpuDevice()
