Problem with Classify Pixel DLPK

I have a problem using DLPK Super Resolution to apply to a Raster.

@johnpol by any chance your model was trained with 3-band rasters and the above errors was thrown when the model was used against a 4-band raster?

Number of bands (and, other properties should match e.g. you train a model with 100 cm resolution images, it might not give the best results on 10 cm images).

Yes, I found the problem, it was that I used a Raster with 4 bands. I forgot to finish this post, althought thanks for the answer jajaja. Trying to train a model with good results

Hello

So if I trained the model with a 3- band raster I won't be able to use it to detect with a 4 band raster? why is that?

I am a newby of arcgis pro. can some one give me a toturial on how to prepare data for this dlpk model?

Use the model—ArcGIS pretrained models | Documentation

i want to try this.
