Hello, may I know the reason behind this error?

python3 demo.py --weights checkpoints/DUSt3R_ViTLarge_BaseDecoder_512_dpt.pth

Hi, could you tell me a little more ?

How many images did you add ?
Do you get this error every time ? -> if yes What if you use more than 3 images, do you still get an error ?

from what I gather:
it crashed during the initialization of
PairViewer -> so 1 or 2 images
self.pred_i = NoGradParamDict({ij: pred1_pts[n] for n, ij in enumerate(self.str_edges)}) -> at this line in the parent class
str_edges was empty ?, it shouldn't be.
