Hi,

I am currently using MONAILabel with CVAT in a Docker environment, utilising the default endoscopy app for 2D segmentation of surgical images. After completing a round of annotation and marking the job as finished, I encountered the following error:

Can't initialize NVML
The version_base parameter is not specified.
Please specify a compatability version level, or None.
Will assume defaults for version 1.1

It appears that the MONAILabel server is failing to download the results due to a corrupted or improperly created archive file. Could someone please guide me on how to resolve this issue?

Many thanks and
Kind regards,
