Error in libSVM Python interface -


i called

 model = svm_model(svm_problem(prob_y, prob_x), svm_param)

but error:

traceback (most recent call last): file "./multiprob.py", line 267, in <module> main() file "./multiprob.py", line 226, in main train_x, train_y, test_x, test_y, param, outfile) file "./multiprob.py", line 89, in testing model[i,j]=base_train(cls_x[i], cls_x[j], param) file "/data/svm/svmprob-1.2/svmplatt.py", line 15, in svmplatttrain model = svm_model(svm_problem(prob_y, prob_x), svm_param) typeerror: __init__() takes 1 argument (3 given)

i view code in /usr/lib64/python2.6/site-packages/libsvm/svm.py

class svm_model(structure): >---_names = ['param', 'nr_class', 'l', 'sv', 'sv_coef', 'rho', >--->--->---'proba', 'probb', 'label', 'nsv', 'free_sv'] >---_types = [svm_parameter, c_int, c_int, pointer(pointer(svm_node)), >--->--->---pointer(pointer(c_double)), pointer(c_double), >--->--->---pointer(c_double), pointer(c_double), pointer(c_int), >--->--->---pointer(c_int), c_int] >---_fields_ = genfields(_names, _types) >---def __init__(self): >--->---self.__createfrom__ = 'python'

the init_ take 1 argument... how fix it?

it libsvm's edition error. libsvm 3.x changes model used in libsvm 2.8.9.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
