BEVFormer运行生成数据脚本时报错

Traceback (most recent call last):
File "./tools/create_data.py", line 10, in <module>
from data_converter import indoor_converter as indoor
File "/workspace/code/BEVFormer/tools/data_converter/indoor_converter.py", line 6, in <module>
from tools.data_converter.s3dis_data_utils import S3DISData, S3DISSegData
ModuleNotFoundError: No module named 'tools.data_converter'

解决方法：

在tools下新建一个空文件： __init__.py
