scipy - numpy.sum() gives `TypeError: sum() got an unexpected keyword argument 'dtype'` -

the next code generated unexpected typeerror:

import scipy.sparse import numpy coomatrix = scipy.sparse.coo_matrix((100,100)) numpy.sum(coomatrix)

the result:

typeerror: sum() got unexpected keyword argument 'dtype'

scipy version 0.14.0, numpy version 1.9.0

the problem numpy.sum doesn't know how handle sparse matrices. next works expected:

coomatrix.sum()

numpy scipy sparse-matrix

Php operator `break` doesn't stop while - have weird issue, break doesn't break while loop , maintain rotating. logically should break cycle , set output while ($c++ != 5) { // here curl request, doesn't relevant have removed preg_match("!<.*?>(\s*)[^<>]*?{$to}<!", $resp, $result) ; // echo 'cnt = ' .count($result).'<br>'; if(!count($result)) { $amount = 0; echo 'sleep called'; sleep(4); exit; continue; } else { $amount = trim(@$result[1]); $amount = round($amount + $amount * $exchange_ratio, $precision); echo 'break happen<br>'; break; } } so output cnt = 2 break happen cnt = 0 sleep called so skipped break , maintain rotating. how so? edit works fine on localhost issue php version? ...
