cannot import name 'womd_camera_utils' from 'waymo_open_dataset.utils'

[lssiair]

Hi, everyone,

I want to get the lidar and camera data in motion prediction task. It shows an import error when I import the script of camera：

from waymo_open_dataset.utils import womd_camera_utils ImportError: cannot import name 'womd_camera_utils' from 'waymo_open_dataset.utils' (unknown location)

Fortunately, the lidar script (womd_lidar_utils) can be imported normally.

Hi @lssiair, could you check the version of the open dataset package you have? Since you can access the lidar but not the camera, I would guess you're still using the old version. Correct version should be: waymo-open-dataset-tf-2-12-0 == 1.6.2

(The pip install at the top of the tutorial needs to be updated)

Thanks for your response, @nicomon24 . I install the new version, waymo-open-dataset-tf-2-12-0 == 1.6.2, but the womd_camera_utils still cannot be imported. Below is my pip-installed list:

Hi @lssiair, thanks for finding this, I was able to reproduce just by running the camera tutorial on colab with the pip package. Let me try to understand what is happening and come back to you asap.

[nicomon24]

Hi @lssiair I can confirm that the error is caused by a missing dependency (basically the camera utils files is not included in what gets packaged on pip). I'm working on a fix, but in the meantime, if you clone the repo and pip install from source it should work.

Hi, @nicomon24 I have imported the camera utils successfully from source. Thanks!
