KeyError: 'is_key_frame' ,can't find the key in record

I have been using the nuscenes dataset before and it performed well. However, the following error occurred recently when loading data. line 126, in init version="v1.0-trainval", dataroot=self.dataroot, verbose=False File "/home/ljh/miniconda3/envs/clip_env/lib/python3.7/site-packages/nuscenes/nuscenes.py", line 124, in init self.make_reverse_index(verbose) File "/home/ljh/miniconda3/envs/clip_env/lib/python3.7/site-packages/nuscenes/nuscenes.py", line 186, in make_reverse_index if record['is_key_frame']: KeyError: 'is_key_frame' The only thing I did during this period was to try to load the data and train the model with pytorch_lighting . How can I solve this problem?

@Liuliuliuyikou without a working code snippet from you (i.e. something a reader can simply copy, paste and run), it is hard to say, but I can suggest a few things to help you:

• Ensure that the nuScenes data is in the correct location
• Print record to see what is being stored in that variable

Thank you, the problem has been solved
