Hello, I have encountered this problem, but I don’t know how to solve it. I hope you can give me some help. Thank you very much.

Hey there,

this is an error I usually get, if the datasets' folder structure is either not correct or if some of the images are missing/broken. In this case the opencv image loading function returns a None object, which has no attribute shape. Maybe you could double check, if the datasets are set up correctly?

Thank you very much for your reply, I will check my data set according to your reply.

Hi @17853313621 I am facing the same issue like you. I am unable to find any broken images in the downloaded dataset so I am not sure what is causing the error. Were you able to solve the problem by downloading the data set again or did you do something else ?

This is because the json file is inconsistent with the folder file, and the image is missing.
