error "AttributeError: 'NoneType' object has no attribute 'shape'" when processing fresh reference images

[m-btt]

Same error occurs for different failures during testing, follows:

Traceback (most recent call last): File "D:\Firefox Downloads\poop main\main.py", line 257, in <module> sort(args) File "D:\Firefox Downloads\poop main\main.py", line 196, in sort classifier.make_ref_db(args.reference) File "D:\Firefox Downloads\poop main\main.py", line 79, in make_ref_db if faces.shape[0] > 1: AttributeError: 'NoneType' object has no attribute 'shape'

Full log of one test run:

Testing more to narrow down root cause, at the moment the suspicion is error is being raised when a face is not found in a reference picture.

ETA: When I say processing fresh reference images, I mean there is no pre-existing references database being used. Upon this error, process is stopped and killed, and no database file is created. No logs either at this moment due to #3

Gathering NOK files so far supports that the issue is likely caused when a face is not identified like mentioned.

KTR examples:

KJY examples:

Propose two actions:

1. When face not identified, ignore and proceed with processing remaining reference pictures;
2. Add event to log

Potential additional one:

3. Move any invalid reference images to an appropriate folder (e.g. invalid-references folder where all invalid reference images found during processing are put)
