Reproduces the problem - code sample

On running

python tools/dataset_converters/update_infos_to_v2.py --dataset kitti --pkl-path ./data/kitti/kitti_infos_test.pkl --out-dir ./data/kitti

I am getting the error

"tasks" must be a tuple object or a sequence object, but got <class 'dict'>

Reproduces the problem - command or script

python tools/dataset_converters/update_infos_to_v2.py --dataset kitti --pkl-path ./data/kitti/kitti_infos_test.pkl --out-dir ./data/kitti



### Reproduces the problem - error message

 "tasks" must be a tuple object or a sequence object, but got <class 'dict'>

### Additional information

1. Code should complete so that I can generate the individual pkl files similar to demo/data/kitti/00008.pkl
2. If this is not possible,please provide link from where individual pkl files for each sample in test can be obtained.
