Error in waymo package when ploting clouds with maps

[073501]

In waymo motion dataset v1.2: I first install waymo_open_dataset package in tutorial.ipynb: I try to plot point clouds with maps and follow the instruction in tutorial_maps.ipynb and I got the error message:

Traceback (most recent call last):
  File "test.py", line 7, in <module>
    from waymo_open_dataset.utils import plot_maps
  File "/opt/conda/envs/waymo/lib/python3.8/site-packages/waymo_open_dataset/utils/plot_maps.py", line 52, in <module>
    class MapPoints:
  File "/opt/conda/envs/waymo/lib/python3.8/site-packages/waymo_open_dataset/utils/plot_maps.py", line 55, in MapPoints
    x: list[float] = dataclasses.field(default_factory=list)
TypeError: 'type' object is not subscriptable

The error message is from waymo package. Is there any bugs in waymo-open-dataset-tf-2-11-0==1.5.1?

Hi. Thanks for bringing this up, are you running this in colab?

I just tested the code and it works correctly from this link in colab.

I had the same error. You need to use a Python version >3.8
