Error Training -> Num_samples = 0

[luda1013]

Hallo Pros, and @srrichter

So i tried to train it, i follow the steps. and for datasets i just use PlayingFromData. because i am stuck at MSeg, by the MSeg, it took 10 minutes for just 1 image and i got only gray image.
because of that, i now have only robust label map (gray images) for folder 01_images and 02_images of Playing for Data

that's why, my dataset:
for real image -> 01_images
for rendered image -> 02_images

i follow the step, and when i wanted to train. i got the following error:

do u know why i got the num_samples = 0?? thank you very much for the help
