Can't run inference_difface.py

[ThiBsc]

By running this command python inference_difface.py --in_path ~/Images/blur/blurred_1.png --out_path ~/Images/blur/unblurred I got error

Here the python command line stack Trace

Our method relies on face detection algorithm? In your case, the detection algorithm can't find any face and thus causes error. Would you please share the testing image with me via the email of zsyzam@gmail.com? I will have a try. @ThiBsc
