CPP examples generate all 0 label

CPP examples generate all 0 label,
After compile the source code, I run the example clustering.sh
But I got all labels 0

And I tried implemented iris example with python (A, b, C, d matrix generated by CPP example)
still got same output

Environment:
Macos 14.1 ARM64 python 3.9

recently I want to implement pairwise-constraint clustering method, But my data has a lot of missing value, so i cant use cop-kmeans. Any help will be very thankful!
