Hmm... I guess they throttle downloads, but I have 5/20 service, how can I upload faster? This is the speed test without secure conection

If x is multidimensional pylab array x.argmax() returns the flat index (converts the multidimensional array into a flat vector before finding the max/min). The pylab function unravel_index comes to our help pylab.unravel_index(x.argmax(), x.shape) From a hint here .
