@openvino-book just tested on master branch (commit: cf73597d05a02a947429488ef695c27933879160) and the example is working fine. Please share the commit you used or simply try again using the latest master. If the issue persists, please share the output of pip freeze, your Python* version and the nncf commit used.

Had this problem, guess its something with new Yolov8 versions. Fixed this by changing in main.py line 149 from: validator.stats = [] to: validator.stats = dict(tp=[], conf=[], pred_cls=[], target_cls=[])

@openvino-book I followed the instruction yolov8_quantize_with_accuracy_control/README.md and I can't reproduce the issues. I checked both Ubuntu and Windows.

NNCF version: 47187e5bbaef678508fdfdc980b258fc4e32d3db Python: 3.9

I closed the issue. Please feel free to reopen it if it still does not work for you, and share the output of pip freeze, your python version, and the NNCF commit used.

Hi, @andrey-churkin: Sure! the problem is fixed accroding to the @dxrsgn 's soluiton, to change the L149 to

validator.stats = dict(tp_m=[], tp=[], conf=[], pred_cls=[], target_cls=[])

I has submitted a PR and hope it's helpful.:)
