Can not open car_models in 3d_car_instance_sample in python3.6

[LovPe]

Hi I tried to open .pkl files in 3d_car_instance_sample/car_models with code in python3.6

roots = r'/home/xxx/3d_car_instance_sample/3d_car_instance_sample/car_models'
files = glob.glob(os.path.join(roots, "*.pkl"))
for each in files[2:]:
    with open(each) as f:
        anns = pickle.load(f)

then a error occur:

    anns = pickle.load(f)
TypeError: a bytes-like object is required, not 'str'

How to fix this error?

There are issues with the pickle files plus some python version incompatibilities. You can download and use the json files instead from this kaggle link. I have fixed some python-version-related errors in my fork so you can have a look if you want.
