Probable mistake in the documentation of the training of LOP4.
In the file https://vcgit.hhi.fraunhofer.de/jvet-ahg-nnvc/VVCSoftware_VTM/-/blob/VTM-11.0_nnvc/training/training_scripts/NN_Filtering/LOP4/readme.md?ref_type=heads, the first line is
python3 src/training/tools/create_config.py src/training/training_scripts/NN_Filtering/common/common_config.json src/training/training_scripts/NN_Filtering/LOP4/lop3_config.json src/training/training_scripts/NN_Filtering/LOP4/model/model.json src/training/training_scripts/NN_Filtering/LOP4/paths.json > my_config.json
Probably, this line should rather be
python3 src/training/tools/create_config.py src/training/training_scripts/NN_Filtering/common/common_config.json src/training/training_scripts/NN_Filtering/LOP4/lop4_config.json src/training/training_scripts/NN_Filtering/LOP4/model/model.json src/training/training_scripts/NN_Filtering/LOP4/paths.json > my_config.json
Moreover, probably, the line
Quantization of the model: See LOP4/quantize/quantize.txt
should rather be
Quantization of the model: See LOP4/quantize/quantize_lop4.txt
