Had trouble with training, seems no img loaded. Could someone show me the structure of the dataset?

The system is win11, but since the codes recognize the path properly when I tried with the swapping functions, so I guess the OS/path style is not the cause.
The final part I got when I started training:

…
…
which_epoch: 10000
-------------- End ----------------

Finished preprocessing the Swapping dataset, total dirs number: 0...

"value, but got num_samples={}".format(self.num_samples))
ValueError: num_samples should be a positive integer value, but got num_samples=0

My images are in the 'root' of the path I used in the training command, yeah, they are all in the same folder. My guess is that my dataset structure/style is different from the official one. But the datasets provided by the authors, especially the 512 one, is toooo large. Could someone show me the structure of the original/official dataset folders so that I can modify mine to make sure the codes can recognize it properly?

BTW, the dataset is the faces of target face from the video, right? For example, if I want to replace the Trump's face in a video, I should use his faces as the dataset, after finishing training, use that specific model, and one image of the other guy, do the swapping?

Thanks in advance!

Hi, I encountered the same problem and the solution are as follows:
Suppose you put the images into SimSwap/dataset. And you are running the code under SimSwap. Then you should set the data path to dataset or ../dataset instead of /dataset.
