Hi,

I’m trying to follow this guide to import text annotations using the Python SDK but I’m getting the following error when executing import labelbox.types as lb_types:

Traceback (most recent call last):
  File "/workspaces/ml-automarking-modelbuild/.venv/lib/python3.9/site-packages/labelbox/types.py", line 2, in <module>

    import geojson
ModuleNotFoundError: No module named 'geojson'

During handling of the above exception, another exception occurred:

    raise ImportError(
ImportError: There are missing dependencies for `labelbox.types`, use `pip install labelbox[data] --upgrade` to install missing dependencies.

After executing pip install labelbox[data] --upgrade, I then get a different error:

I’m using a GitHub codespace and the following Python 3.9.17 docker image mcr.microsoft.com/devcontainers/python:3.9 and developing within a virtual env with no packages installed other than labelbox

Hi @tw974 ,

Labelbox uses a few dependencies : https://github.com/Labelbox/labelbox-python/blob/develop/requirements.txt

I would recommend you to install labelbox[data] instead to make sure you have all dependencies installed.

pip install "labelbox[data]"

refer to : labelbox · PyPI

Many thanks,

Thanks for your reply @PT, I have tried to install labelbox[data] directly in a fresh environment but still get the same error…

weird, I have provided the requirement list (https://github.com/Labelbox/labelbox-python/blob/develop/requirements.txt), I guess you can pass them in your env and this will sort your issue.

The error is due to opencv-python not being properly installed.

A solution for me was to manually install the missing dependency libgl1 inside my codespace docker container following this:

Now it works fine. Thanks for your support
