Hello @shoghilin When running the training command in the last line of the setup.sh script, I received the following error:

I think it is a dataset issue. Can you check dataset has been processed successfully or not?

I rebuilt the project, and it ran perfectly fine. Please make sure you have downloaded the dataset to the root of this project, and name the folder "car-plate-detection". PS, I updated README.md in case it is not clear enough.
