RuntimeError when running the Tracktor inference code about mmtracking HOT 5 CLOSED

Please do not use 8 GPUs.

There are only 7 videos in the MOT dataset.

from mmtracking.

I have tried GPUs with 4, 5, 6, 7 instead, but all results in the same error above.
I think the error message indicates there are some empty rois.

cannot reshape tensor of 0 elements into shape [1, 0, -1] 

Any suggestions?

That's weird. Are you using the datasets we provided and directly run the commands? It seems that there are empty tensors that make the error. Which detector are you using?

I have the same problem!
[RuntimeError: cannot reshape tensor of 0 elements into shape [1, 0, -1] because the unspecified dimension size -1 can be any value and is ambiguous]
I downgrade the mmdet from 2.11.0 to 2.9.0, and problem solved! Don't forget to install mmcv-full. I use version 1.2.7
I also found that mmdet in 2.11.0 is Incompatible when I want to train the model on my datasets.
Hope this might help you!

Hi all, this bug is caused by a feature update in MMDetection.
I have already fixed it in mmdetection, will be available in 2.12.0.
