i have implemented multinomialnb message. please me solve it. here code : kf = kfold(len(x), n_folds=2, shuffle=true, random_state=9999) model_train_index = [] model_test_index = [] model = 0 k, (index_train, index_test) in enumerate(kf): x_train, x_test, y_train, y_test = x.ix[index_train,:], x.ix[index_test,:],y[index_train], y[index_test] clf = multinomialnb(alpha=0.1).fit(x_train, y_train) score = clf.score(x_test, y_test) f1score = f1_score(y_test, clf.predict(x_test)) precision = precision_score(y_test, clf.predict(x_test)) recall = recall_score(y_test, clf.predict(x_test)) print('model %d has accuracy %f | f1score: %f | precision: %f | recall : %f'%(k,score, f1score, precision, recall)) model_train_index.append(index_train) model_test_index.append(index_test) model+=1 and result : indexerror traceback (most recent call last) <ipython-input-3-df0b24edb687>...

i'm working through rxjskoans , i'm seeing recurring pattern of feeding in array of results, subscriber pushes new values onto: var rx = require('rx'), subject = rx.subject var result = []; var s1 = new subject(); s1.subscribe(result.push.bind(result)); s1.onnext('foo'); result; // ['foo'] this impure function; result array mutated subscribe. i've seen small-scale projects on github make stab @ using immutable.js, none actively maintained. im wondering if there's widely-adopted immutable implementation pattern, , if not, why? i wouldn't call pattern, since can pass through stream can pass in immutable data structure: const stream$ = rx.subject.create(); stream$ .map(data => data.set('a', data.get('a') + 1)) .subscribe(data => console.log(data)); stream$.next(immutable.map({ a:1 })); stream$.next(immutable.map({ a:2 })); <script src="https://npmcdn.com/@reactivex/...

i have custom radio buttons on application. issue radio buttons display fine individually. when try have 2 of them in 1 line... appear on each other instead of beside each other. can't change html , can mess css. appreciated. thinking due width of each label giving low width had same result. html: <label class="radio"> <input type="radio"> <span class="custom"><span>one</span></span> </label> css: * { box-sizing: border-box; } input[type="radio"] { display: none; cursor: pointer; } label { cursor: pointer; } .radio span.custom > span { margin-left: 22px; } .radio .custom { background-color: #fff; border: 1px solid #ccc; border-radius: 3px; display: inline-block; height: 20px; left: 0; position: absolute; top: 0; width: 20px; } .radio input:checked + .custom:after { background-color: #0574ac; border-radius: 100%; border: 3px solid #fff; conten...

is there quick method find shortest repeated substring , how many times occurs? if there non need return actual string ( last case ). >>> repeated('ctctctctctctctctctctctct') ('ct', 12) >>> repeated('gatcgatcgatcgatc') ('gatc', 4) >>> repeated('gatcgatcgatcgatcg') ('gatcgatcgatcgatcg', 1) because people think it's 'homework' can show efforts: def repeated(sequentie): string = '' in sequentie: if not in string: string += items = sequentie.count(string) if items * len(string) == len(sequentie): return (string, items) else: return (sequentie, 1) your method unfortunately won't work, since assumes repeating substring have unique characters. may not case: abaabaabaabaabaaba you on right track, though. shortest way can think of try , check on , on if prefix indeed makes entire string: def f...
