About prerendering testing data

[arya-snh]

The prerender/prerender.py script doesnt seem to work on the testing tfrecords in Waymo motion dataset. An error occurs in the prerender/utils/vectorizer.py script. Please help.

Hi @arya-snh, How did you solve this issue?

As far as I remember, some records in the dataset have missing roadgraphs, thus it fails here. You might want to use another version of the dataset or allow for empty roadgraph.

Thanks a lot. I will skip those data points.
