ERROR about waymo_dataset_v2.0.0

[Cxz-dev]

I followed the tutorial_v2, but got an error as follows：

My code is：

@title Initial setup

from typing import Optional import warnings warnings.simplefilter(action='ignore', category=FutureWarning)

import tensorflow as tf import dask.dataframe as dd from waymo_open_dataset import v2

dataset_dir = '/home/cxz/waymo_dataset_v2.0.0'

context_name = '10504764403039842352_460_000_480_000'

def read(tag: str) -> dd.DataFrame: """Creates a Dask DataFrame for the component specified by its tag.""" paths = tf.io.gfile.glob(f'{dataset_dir}/{tag}/{context_name}.parquet') return dd.read_parquet(paths)

lidar_df = read('lidar') lidar_pose_df = read('lidar_pose')

Anyone can give me some suggestions？ Thank u！

I have the same issue. So how to solve it?

[Erin-July]

I solved this problem by replacing python 3.8 with python 3.9. conda install python=3.9

Hi @Erin-July

Thanks for posting! Just let you know that python 3.10 has been tested: https://github.com/waymo-research/waymo-open-dataset/blob/master/src/waymo_open_dataset/requirements.txt

If you run into another issue, it might be good to follow what's suggested.

Since you have resolved the problem, can we close the ticket now?
