Waymo validation issue - Githubissues

Hi there, thanks helping me out previously with the Waymo dataset creation. I did managed to create the dataset and have successfully tested the training for pointpiller model as an example, but in the evaluation phase i an get error KeyError: 'pred_instances_3d', in my evaluation configuration and its something like this

val_evaluator = dict(
    type='WaymoMetric',
    ann_file="data/waymo/kitti_format/waymo_infos_val.pkl",
    waymo_bin_file= "data/waymo/waymo_format/gt.bin",
    data_root='data/waymo/waymo_format',
    backend_args=backend_args,
    convert_kitti_format=True,
    idx2metainfo='data/waymo/waymo_format/idx2metainfo.pkl'
    )

I have tried to follow the instruction on this path

The error is out it 11/28 00:21:27 - mmengine - INFO - Epoch(test) [39900/39987] eta: 0:00:07 time: 0.0922 data_time: 0.0021 memory: 368

    if len(self.results[res_index]['pred_instances_3d']) > 0:

I have also tried removing the idx2metainfo and using the normal one

val_evaluator = dict(
    type='WaymoMetric',
    ann_file="data/waymo/kitti_format/waymo_infos_val.pkl",
    waymo_bin_file= "data/waymo/waymo_format/gt.bin",
    data_root='data/waymo/waymo_format',
    backend_args=backend_args,
    convert_kitti_format=False)

and i use to get the below erro

Did you encounter such errors while you where running your models ? Would really appreciate your help with this if possible!
