How can I write pixel label datastore to file?

Hi, I am now trying with semantic segmentation by reffering to the steps in

mathworks.com/help/vision/ug/semantic-segmentation-with-deep-learning.html#mw_44be2a2e-ec6b-4a03-9470-ea945f74515e

But I faced problem when I want to show and save the predicted segmentation images from datastore to my computer. May I know what should I add on after 'pxdsResults'?

H='D:\data\desktop\New\testing_1';

K=dir(fullfile(H,'*.png'));

total_images=numel(K);

for n=1:total_images

f=fullfile(H,K(n).name);

I11=imread(f);

I12=imresize(I11,[300 300]);

I13=double(I12(:,:,1));

I14=medfilt2(I13);

L_1='D:\data\desktop\New\test_image';

path1=fullfile(L_1,K(n).name);

imwrite(I14/255,path1);

end

imdsTest = imageDatastore(L_1);

pxdsResults = semanticseg(imdsTest,net,"WriteLocation",tempdir);

I also tried to write the output into computer folder first, then save the output into pixel label datastore, but it failed also, the command window shows 'Not enough input arguments.'

H='D:\data\desktop\New\testing_1';

K=dir(fullfile(H,'*.png'));

total_images=numel(K);

for n=1:total_images

f=fullfile(H,K(n).name);

I11=imread(f);

I12=imresize(I11,[300 300]);

I13=double(I12(:,:,1));

I14=medfilt2(I13);

L_1='D:\data\desktop\New\test_image';

path1=fullfile(L_1,K(n).name);

imwrite(I14/255,path1);

testImage=I14;

I15 = semanticseg(testImage,net);

I16 = labeloverlay(testImage,I15);

figure(n);

L='D:\data\desktop\New\test_result';

path2=fullfile(L,K(n).name);

imwrite(I16,path2);

end

imdsTest = imageDatastore(L_1);

pxdsResults = pixelLabelDatastore(L);
