QCNet: test error

Hi, your work is great. I try to generate the prediction results on the test set by following your code:

python test.py --model QCNet --root /path/to/dataset_root/ --ckpt_path /path/to/your_checkpoint.ckpt

But there is some error like this:

Global seed set to 2023

Traceback (most recent call last):

    super(ArgoverseV2Dataset, self).__init__(root=root, transform=transform, pre_transform=None, pre_filter=None)

  File "/content/QCNet/datasets/argoverse_v2_dataset.py", line 190, in process
    map_data = read_json_file(map_path)
TypeError: object() takes no arguments

Wondering what’s the reason and how to deal with it. Thank you very much.
