Hi,

I met below error when running generate_gt command. Please help. Thanks.
python generate_gt.py --recordings_basedir /data/comma2k19/Chunk_1 --openpilot_dir /data/openpilot --path_to_model /data/openpilot-pipeline/common/models/supercombo.onnx ,
Finding segment directories...

I noticed this is related to cache folder, if I remove and run again this issue is gone. However I met another issue that common.gpio not found. Any clue about this? Here is the log: ```
