This error is being thrown because of the second argument being passed to pixelLabelImageSource, pxdsTrain, which is of type ImageDatastore rather than PixelLabelDatastore. You need to ensure the second argument is of type PixelLabelDatastore (https://www.mathworks.com/help/vision/ref/pixellabeldatastore.html). The following documentation page gives more information on the function arguments: https://www.mathworks.com/help/vision/ref/pixellabelimagesource.html

Note from this documentation page that this function, pixelLabelImageSource, has been removed since R2018a.
