Inference error on windows #62

Open lqxisok opened 1 year ago

lqxisok commented 1 year ago

I have built the extensions and then attempt to run a demo of sfm_bench provided at the readme. But after several tries, I always get an error with the following message:

ii, jj = torch.as_tensor(es, device=self.device).unbind(dim=-1)
ValueError: not enough values to unpack (expected 2, got 0)

An interesting observation is the images of the sfm_bench demo could be shown usually. While, when entering into the driod.terminate() function, the program crashes with the above error. I find that the value of delta.norm(dim=-1).mean().item() (in motion_filter.py) is strange ( ~0.0027 ). As the filter_threshold is set at about 2.4, I guess the frame data can not be added into self.video

My question is does it only happen on windows? I will give try on ubuntu to take a further test. Thx for reply.

Was this ever solved on Windows?
