Problems about converting the waymo dataset

I found that the _calculate_num_points_in_gt is extremely slow in my pc, is that reasonable? Seems it got stuck in this function.

In this case, suggest not using multi-process.

Hi, I found that the problem was caused by the ret_infos = mmengine.track_parallel_progress(self.calculate_single, infos, self.num_worker) as you said. I set the number of workers to 1, but it still stuck there. Is there any way to just run the calculate_single. I used the following code to replace the original one, it works.
