May I ask if the weights in the folder 'weights' have been trained? The results I obtained seem to be inaccurate, is it because I didn't train and used them directly?

I tried using the weight file under weights to directly predict heart rate, but the results were not stable. So, I tried following the method in the readme and checked the RPPG signal using the test set. I found a huge difference between the RPPG signal and the label. Is this difference because the model I am using has not been trained?

I need some details to determine whether you have correctly loaded the pre-trained weights. If possible, you could try testing on the PURE or UBFC-rPPG datasets, as the model usually performs well on these datasets. If you would like more suggestions, you could post your code for loading the weights and conducting the tests.
