How do I convert a Collection Column into a Distance Matrix Columns?
I have a python script generate a custom distance measure table which I then convert into a collection column. However, the k-medoids node does not recognise this as a distance matrix :-(
Hi all. I am wondering if since 2016 there is now an improved way of making custom distance matrixes using python. Perhaps there is a way to convert/cast a numpy matrix or pandas table to a format that knime can recognize? Would love to avoid having to round-trip to a file. Cheers!
