It's very strange to have to catch errors correctly in a test script ? a bit contradictory.

Thanks a lot !

Sounds like you keyboard has not the same values for the keys. Try to print the key value to check when pressing the key what value it has

No, it is the diagonal mode to draw faster the rectangle from the diagonal. You can switch this mode off.

I wrote the maths, just a few things to change, a good exercice :) tell me if you implement and test it :) http://christopher5106.github.io/big/data/2016/04/18/spatial-transformer-layers-caffe-tensorflow.html#rotation

Once your centroïds are computed, have you tried to compute the number of elements in each cluster ? it might be there is a collapse where all boxes fall into...

yes

It might be you have in your dataset a few anchors 'very different' and these atypic anchors can create their own cluster of 1 element...

I propose you run the assignment on the anchors you got and you'll tell me the number of elements per cluster. That will give me the only way to analyze...

right, and then compute the number of elements per cluster.
