Thank you for your wonderful work. While trying, I encountered a very strange problem

When evaluating, all results are 0

Then I checked the data and there was no problem. Self. infos was able to read it normally, but for some reason, the annos of the data became empty.

It seems to be a problem with data parsing, with incorrect data on the left and normal data on the right.

I suspect this may be related to the version I downloaded from the waymo dataset. The version I downloaded is

I also discovered a version later. I'm not sure if this version is the waymo data you used. The link is:
