what are the wrong with this code??

pxds= pixellabeldatastore(pxDir,classes,labelIDs)

Error using pixellabeldatastore

Too many input arguments.

what are the wrong with this code??

@fatima ismail - which version of MATLAB are you using?

What does this show

whos pxDir
whos classes
whos labelIDs

Using a folder of example images that ships with MATLAB, I was able to run your code in R2021a once I updated the labelIDs to be an array of numbers.

classes = ["biling" "car" "pedestrian" "Road" "Sky" "greens" "pole" "Pavement"];
labelIDs=[237 252 0;
    169 0   189;
    252 0   0;
    77  77  77;
    0   45  172;
    92 155 3; 
    119 127 3; 
    255 128 5];
pxDir = fullfile(matlabroot,'toolbox/vision/visiondata/stopSignImages');

pxds= pixelLabelDatastore(pxDir,classes,labelIDs)

pxds = 
  PixelLabelDatastore with properties:

                       Files: {41×1 cell}
                  ClassNames: {8×1 cell}
                    ReadSize: 1
                     ReadFcn: @readDatastoreImage
    AlternateFileSystemRoots: {}
