Segmentation Fault in flow_predictor_raft.py script

[hadillivvy]

Hello! I've been facing a segmentation fault error right after running the flowmap.overfit script and it seems to be from this block of code in flow_predictor_raft.py (line 41):

flow = [
            self.raft(
                source_chunk * 2 - 1,
                target_chunk * 2 - 1,
                num_flow_updates=self.cfg.num_flow_updates,
            )[-1]
            for source_chunk, target_chunk in zip(
                bar(source.split(self.cfg.max_batch_size)),
                target.split(self.cfg.max_batch_size),
            )
        ]

Here is the stack trace: python -m flowmap.overfit dataset=images dataset.images.root=/home/hadil/Work/flowmap/data rm: cannot remove 'outputs/local': No such file or directory Precomputing optical flow. Computing RAFT flow: 0%| | 0/1 [00:00<?, ?it/s]Fatal Python error: Segmentation fault
