It seems to be a bug in both branch master and hagridv2-1m

When I train the code with following command, the program reports an error.

python run.py -c train -p configs/SSDLiteMobileNetV3Large.yaml

I found that the error occurs in the dataset.py

Traceback (most recent call last):
  File "/home/project/Hagrid/run.py", line 88, in <module>
    run(args)
  File "/home/project/Hagrid/run.py", line 54, in run
    train_dataloader, val_dataloader, test_dataloader, model = load_train_objects(config, args.command, args.n_gpu)
  File "/home/project/Hagrid/custom_utils/train_utils.py", line 89, in load_train_objects

  File "/home/project/Hagrid/dataset/dataset.py", line 175, in __getitem__
    for i in range(len(row["united_bbox"])):
TypeError: object of type 'NoneType' has no len()

It seems to be a bug in both branch master and hagridv2-1m.
Because the united_bbox row in .json file usually is None.

The code works well with the following adjustments. But I'm not sure if this will train correctly, because I'm not sure what the united_bbox does

Hello! Thank you for your interest in HaGRID.

I have reviewed the training process for SSDLiteMobileNetV3Large and did not encounter the errors you mentioned. Could you please verify that you have downloaded the correct version of the annotation files (from the master branch)?

Hello! Thank you for your replay.

Yes, I'm sure the annotation file is downloaded from the master branch. And I tried it agin, it does have some gestures with NULL united_bbox.

Finally, I'm guessing this could be a problem caused by a different python version. My conda environment with Python 3.8, which is lower than master branch. It is possible that higher versions of Python will make additional judgments about len(null)
