Im using Sagemaker studio lab, its a managed notebook and still face the following error

~/.conda/envs/default/lib/python3.9/site-packages/ultralytics/yolo/engine/predictor.py in
30 from pathlib import Path

34 from ultralytics.nn.autobackend import AutoBackend

ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory

In my case (on NixOS, but should work for other distros too) it was enough to install the headless version:

pip uninstall opencv-python
pip install opencv-python-headless

Yup @turbotimon and @Badrabu the error you're encountering, ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory, typically occurs in scenarios involving GUI applications or libraries on systems that lack the necessary GUI support libraries. This can happen when using the GUI version of OpenCV on a non-GUI (headless) operating system.
