About datapropress

I have a confusing about dataprocess. I find that you resize the frame in face_detector.py in line68 when you create VideoDatasset. Will it decrease the final result? And the resize operator it is neccessory or not if I want to use dataprocess like this for other model?

This part has been hugely inspired by Selim Seferbekov work: https://github.com/selimsef/dfdc_deepfake_challenge/blob/master/preprocessing/face_detector.py
We maintained the frame resize to be totally comparable, anyway, we think that it would not affect the result. Maybe you can try to remove it and see what happens.

Thanks a lot

I try to cancel the resize operator and a error come like the follow picture. Maybe if you don't resize the computer doesn't have enough resource to execute the code?

Can you provide the full stack trace?

Sorry for replying so late. In the end ,I didn't change it. But I have another question. I use MTCNN to extract face.The thresholds is set as same as yours. In this situation, I find some videos such as NT/808_829.mp4 can not extract enough faces as the paper mentioned. And I try to decrease the thresholds. But some frames are not face. What should I do?
