With your model and the same changes you made (but the original classes.txt file), I got “airplane 0.34” for the 1st test image, no results for the 2nd one, and “car 0.70” for the 3rd one. Are these the same as what you see? If not can you please upload your test result on the 1st image? I haven’t been able to see what other changes need to be made yet…
