tuple index out of range

[wch1996]

Dear ygabuev,Thank for your hard work!
It seems an error in 11th line of utils.py.
This line is "img_array = img_array.mean(axis=2)".The axis only can choose from [0,1],so maybe you can check it.From your process,it seems you want to get the image's luminance channel.Can you explain the process?
Thank you!

Hi @wch1996 !
Here, the input is RGB images, which have shape [height, width, color]. To simplify things, we convert them to b/w by averaging over the color channel. The parameter would be better called "brightness" then "luminance", but I don't remember what the guys were doing in the paper originally :)
Thus, if your dataset has only one color channel, you can pass luminance=False to the function. Does that answer your question?

Thanks for your answer!I have solved the problem.I have another question about the function "crop_by_nan" in utils.py.I want konw why is the program producing 'nan'. Looking forward to your answer!

Hmm, I see that the function is used only during evaluation and that the model may indeed produce NaNs. I don't quite remember why it does so, but my hypothesis is that there may be some artifacts on the edges of a picture. You may want to check it yourself, sorry :(
