Combining lidar data with multispectral bands for deep learning

RitikaPrasai1

I combined the lidar band with multispectral NAIP bands though layer stacking and exported training samples from ArcGIS Pro and then tried to use unet classifier algorithm in jupyter notebook where it gives me the error message as the input was expecting 4 channels but it got 5 channles. There is not any error in code since it runs well with the NAIP (4 bands) but it is showing error when i give it the 5 bands data. Any useful suggestions? Here is the screenshot of the error message.
