Hi Dario, <div><br></div><div>In general it gets a little hard to understand the errors when you </div><div>have templates. Just by aligning the error and seeing what is <div>going on will help to understand the cause of the problem. </div>
<div><br></div><div>It looks like you are passing integers to the </div><div>computeminmax function whereas it is expecting </div><div>float values. My guess is that if you change your </div><div>threshold values to float the code should work fine. </div>
