I was trying to follow the Waymo motion dataset tutorial: .ipynb.

It shows an error like

tensorflow.python.framework.errors_impl.InvalidArgumentError: {{function_node __wrapped__ParseExampleV2_Tdense_55_num_sparse_0_ragged_split_types_0_ragged_value_types_0_sparse_types_0_device_/job:localhost/replica:0/task:0/device:CPU:0}} Feature: roadgraph_samples/dir (data type: float) is required but could not be found. [Op:ParseExampleV2]

Seems like the structure of the data item is different from what is mentioned in the tutorial code?

Any suggestion is appreciated.
