Error about Create Kitti-format data for sv3d-inf #8

Closed shb9793 closed 2 years ago

shb9793 commented 2 years ago

When I ran the following command:

python tools/dataset_converter/dair2kitti.py --source-root ./data/DAIR-V2X/DAIR-V2X-I/single-infrastructure-side \
--target-root ./data/DAIR-V2X/DAIR-V2X-I/single-infrastructure-side \   --split-path ./data/split_datas/single-infrastructure-split-data.json \   --label-type lidar --sensor-view infrastructure

The error was encountered as follows:

================ Start to Convert ================

    i15 = str(-item["rotation"])

should be changed to

 i15 = str(-eval(item["rotation"]))

Because item["rotation"] is a str type, not float type.

some thing still wrong with i15 = str(-eval(item["rotation"])) because item["rotation"] is a float type in my computer, to avoid this question. I just using i15 = str(-float(item["rotation"])) to ensure the type of item["rotation"].
