Evaluation on waymo opendataset

[QingXIA233]

Hello, in order to reproduce the waymo results by my own, I trained CenterFormer on waymo and tried to get the performance evaluation like that shown in the README: I follwed the instruction from https://github.com/waymo-research/waymo-open-dataset/blob/master/docs/quick_start.md, I already have the gt.bin and preds.bin of CenterFormer, but I ran into this error: I wonder whether you encounted this issue before, or maybe I've gone to the wrong way? Really need some help here. Please. Thanks in advance.
