Hi, thanks for the feedback. Currently there is not an easy way to extract a center polyline for crosswalks. This is something we could add in the next release. We...

Hi. The metrics server code uses all of the tracks_to_predict objects in all of the scenarios in the validation set to compute the metrics. Which objects are you including?

Sorry for the late reply. Could you try changing the first dimension to the number of scenarios?

Hi, please take a look at this thread. It has information about how to load Scenario protos: https://github.com/waymo-research/waymo-open-dataset/issues/343

The polygons are not sampled at 0.5 meters as the lane centers and boundaries are. To plot them you need to connect the individual points within the polygon rather than...

The only way to match tf.Example data to Scenario protos is to find the records with matching IDs. The two datasets do not store examples in the same order. Could...

I see. Currently this is a challenge. We plan to open source the conversion code from Scenario protos to tf.Examples in the next release. This will make this task much...

Yes, by matching I meant finding a tf.Example with a scenario/id field that matches the scenario_id field in the Scenario proto. As far as timeline for the next release, I...

We don't currently provide any explicit labels for turn lanes. We do provide the connections between lane center segments which could be used to determine if a lane is turn...

I can look into this Eugene. Are you using the Scenario proto format or the tf.Example proto format? It would be helpful to have the scenario ID and if possible...
