Issue with example code about nuscenes-devkit HOT 4 CLOSED

Hi and thanks for your interest in nuScenes. My guess is that you did not correctly setup Python 3.7 as described here. Hence the typing features are not supported. Please check the following:

• Is your virtual environment enabled? You can do this with workon nuscenes. Your bash prompt should look like (nuscenes) user@machine:~/nuscenes-devkit$.

• Do you have the correct Python version? Run python --version and see if it returns Python 3.7.0.

Please let me know if this works.

Yes you were right, python 3.7 was not installed. I still have problems though with the python script. It does not recognise the nuscenes_utils folder and while executing an error comes up:

Traceback (most recent call last):
File "examples/export_pointclouds_as_obj.py", line 11, in
from nuscenes_utils.data_classes import PointCloud
ImportError: No module named 'nuscenes_utils'

It must be a silly thing but I can't figure it out. Hope you can help me.

You need to add the folder to your $PYTHONPATH. You can either do that every time you open a terminal with:

export PYTHONPATH="${PYTHONPATH}:$HOME/nuscenes-devkit/python-sdk"

You can also add it once in your ~/.bashrc or if you have setup the virtual environment in ~/.virtualenvs/nuscenes/bin/postactivate. For more details see https://github.com/nutonomy/nuscenes-devkit#devkit-setup

Thanks a lot!
