Question

How to add label to each object/ row in distance file in Orange?

I've tried as the example in this link

4
john   0.1
joe    0.5    0.3
jack   0.7    0.9    0.2
jane   0.2    0.8    0.6    0.5

but Orange give the following error:

Error while reading the file: 'invalid literal for int() with base 10:'john"

Answer 1

Example is broken. It should be like this:

4 labelled
john   0.1
joe    0.5    0.3
jack   0.7    0.9    0.2
jane   0.2    0.8    0.6    0.5
