Error using greedy_IPD(Testdata,dims,35)

[alifarhat40]

Hello,

@niclaspopp
I am having trouble running this basic command. I updated all relevant packages, but I am not sure how to debug this. Any help please?

ipd = greedy_IPD(Testdata,dims,35)

Hi alifarhat40, thanks for asking the question and pointing out the error! It seems like the error comes from the call of kmeans in line 225 as both StatsBase and Distances export the same function (which has been changed since the release of the package). Thus, it has to be specified which package to use. I'll try to debug that and test it and will push the fix when it's working.

Thanks.

I don't know why they say it has been resolved here even though it still gives same error:

JuliaStats/Clustering.jl#274 (comment)

@niclaspopp

I did some changes and managed to get all the functions to run except for the function:

ipd_clustered = greedy_IPD_clustered(Testdata,dims,35,3);

Any idea why it does not run?

Also, can you help me interpret your output here for the ipd = greedy_IPD(Testdata,dims,35)

What do the values here represent? are those the bin index for each data point per dimension?
