Validate problem

[JhoeGabri]

I've been trying to validate the RealESRGAN training by uncommenting the lines that are commented and adding the paths for the validation part of the dataset. However, when I execute the training, it says that "801.png" (the image that is part of the validation) is not in the path list. I saw that the validation requires a paired image dataset, so I created a meta_info file using the generate_meta_info_pairdata.py script for the LR and HR images of the validation, but it still says the same.

The question is, in the training.md file, they don't specify if all the images need to be in the meta_info text file that needs to be created. So, in order to validate, what exactly needs to be in the meta_info file? Additionally, can someone share their meta_info file where the validation works?

Thanks.
