Chameleon graphtool.py: A value is trying to be set on a copy of a slice from a DataFrame.
the-beee opened this issue · comments
After running the following command:
df=cluster(data,k=10,knn=10,m=data.shape[0]//100,alpha=1.0,plot=False)
the algorithm shows the following warning but still proceeds naturally. I'm wondering if this is gonna affect the results?

Hi!
It should not affect the results, anyway, I am going to correct this, thanks for reporting this
With the new version, 0.0.7, the warning should not be printed
Thanks mate!
