What's the purpose of unused LR_Rasters=[] in last 2 code cells?

[iam-Shashank]

Hey Jacob, great work!

I wanted to know whether the LR_Rasters=[] in last 2 cells ( inference cell, performance testing cell) of the notebook are of any use?

Also, I am working with jpegs, so replaced .tif with .jpeg. In the 2nd last cell, just after LR_Rasters=[] there's driver = gdal.GetDriverByName("GTiff"), is there any need to replace the GTiff here with JPEG? Although I did run and get output images, I am asking anyway.
