Detectron2 ImportError

[julian-voss]

Thank you very much for this great project.

After following along the usage instructions I ran into a Detectron2 ImportError error when trying to initialize the model backend server:

\~\Desktop\repos\Detectron2_AL>label-studio-ml init labeling/backend_model --script\annotating/backend_model.py --force

ImportError: DLL load failed while importing _C: The specified module could not be found

I'm using Windows 10. In order to install detectron2 I have download the files from this source and made the required changes proposed by this tutorial before installing the library.

Do you have an idea on what could cause this issue? Any help would be much appreciated.
