i have been using older version of stanford nlp, switch newest, coolest algorithms. looked @ demo of nn dependecy parser , don't know how integrate corenlp pipeline. i using jython code: props = properties() props.put("annotators","tokenize,ssplit,pos,lemma,parse") props.put("isonesentence",true) pipeline = stanfordcorenlp(props) but i'd use newer algorithms. possible current pipeline? if not, easy way rewrite this, produces same results without annotation pipeline? thanks in advance! pavel the annotator you're looking "depparse", not "parse". so, code like: props = properties() props.put("annotators","tokenize,ssplit,pos,lemma,depparse") props.put("isonesentence",true) pipeline = stanfordcorenlp(props) note no longer have constituency trees ( tree ) after this, dependency tree ( semanticgraph ).

i have followed multiplayer shootout showcase ( https://docs.unrealengine.com/latest/int/resources/showcases/blueprintmultiplayer/index.html ) , tried replicate sessions part own project. can create (lan) session, see other sessions , join one. problem that, reason, correct map opens, actors not replicate. if open map, 2 players, replicate without issues. there else should enable replications when using sessions? thank you! after further testing program, gave me following error:lognet:warning: travel failure: [loadmapfailure]: failed load package '/game/maps/uedpie_2_arena2'. found out because testing game sessions inside editor. after tried testing in standalone game mode, working fine.

i want linear regression scatter plot using polyfit, , want residual see how linear regression is. unsure how isn't possible residual output value polyfit since 1 dimensional. code: p = np.polyfit(lengths, breadths, 1) m = p[0] b = p[1] yfit = np.polyval(p,lengths) newlengths = [] y in lengths: newlengths.append(y*m+b) ax.plot(lengths, newlengths, '-', color="#2c3e50") i saw stackoverflow answer used polyval - unsure of gives me. exact values lengths? should find error finding delta of each element polyval , 'breadth'? you can use keyword full=true when calling polyfit (see http://docs.scipy.org/doc/numpy/reference/generated/numpy.polyfit.html ) least-square error of fit: coefs, residual, _, _, _ = np.polyfit(lengths, breadths, 1, full=true) you can same answer doing: coefs = np.polyfit(lengths, breadths, 1) yfit = np.polyval(coefs,lengths) residual = np.sum((breadths-yfit)**2) or residual = np.std(breadths-yfit)**2 * len(b

i've got code (using python 3.4, django 1.7, , postgresql) pushed heroku. worked fine until added login. on local machine, used shell add user, create password, , save user/password. pattern worked locally, foreman. the setup seems have worked: heroku run python3 manage.py shell = user.objects.get(id=1) the server returns <user: {'username':'me'}>. asking a.password returns hashed password changes when a.set_password('blah') , a.save() . that's , normal, except username/password (unhashed) won't log me in. when run: heroku run python3 manage.py changepassword me heroku responds with: commanderror: user 'me' not exist how can user saved , retrievable in shell, implying it's in database, not found otherwise using "manage.py changepassword"? most importantly, how can log website on heroku? ****edit**** ran python manage.py createsuperuser in heroku shell create user log in. once did, saw none

hi try create input function function through vector. however, don't know why input become infinite loop? do { cout << "please enter next number: "; cin >> num; number.push_back(num); cout << "do want end? enter 0 continue."; dec = null; cin >> dec; } while(dec == 0); "i don't know why input become infinite loop." the reason can imagine is, incorrect input sets cin fail state. in case (e.g. invalid number entered, or enter pressed) cin set fail state , value in dec won't change evermore. once cin in fail state subsequent input operations fail respectively, , subject input won't changed. to proof against such behavior, have clear() std::istream 's state, , read safe point, before proceeding (see also: how test whether stringstream operator>> has parsed bad type , skip it ): do { cout << "please enter next number: ";

( https://developers.google.com/maps/documentation/staticmaps/#pathstyles ) the last byte (two hex digits) indicates transparency in 1/255ths. when not given, defaults 50%. so set color 100% opacity, add ff @ end.

i've been reviewing eugene myers' diff algorithm paper . algorithm implemented in popular diff program. on page 12 of paper, presents pseudo-code algorithm find longest common sub-sequence of a , b : lcs(a, n, b, m) if n > 0 , m > 0 find middle snake , length of optimal path , b. suppose (x, y) (u, v). if d > 1 lcs(a[1..x], x, b[1..y], y) output a[x+1..u] lcs(a[u+1..n], n-u, b[v+1..m], m-v) else if m > n output a[1..n]. else output b[1..m]. suppose = "a" , b = "b". in case, n = 1 , m = 1. middle snake (x, y) = (0, 1) , (u, v) = (0, 1) because there no diagonals. in case d = 1 because algorithm has taken 1 step. the algorithm says thing in scenario output b[1..m] , equal "b", because n > 0, m > 0, d = 1, , m = n. seems wrong, because there no common sub-sequence between "a" , "b". paper's com

so here thing. need to call php page link ( <a href='name.php'> ) access database , print information specific links. think code more clear question: <?php session_start(); //start session capture usrname processlogin.php $usrname=$_session['usrname']; $query = "select est_name students usrname=".$usrname."; $result = $db->query($query); while( $row = mysqli_fetch_array(($result))) { echo "<a href="showprofile.php">".$row['est_name']."</a>"; //i need click here , show information in database //for specific student } ?> my question is: there way name specific link can use information want specific student? change link tag provide id in query parameters. echo "<a href=\"showprofile.php?id={$row['id']}\">{$row[&#

i have code: list<integer> list1 = new arraylist<integer>(); list1.add(100); list1.add(200); list1.add(300); list1.add(400); list1.add(500); list1.add(600); integer lastelement = list1.get(list1.size()-1); system.out.println("values of list:" + list1-lastelement); !!! the values of list should be: 100, 200, 300, 400, 500. , list1-lastelement gives me error! there other way it? what trying subtract value 600 (the last value of arraylist) length of arraylist. makes no sense. instead try following (if trying print last element): for (int = 0; < list1.size() - 1; i++) { system.out.println(list1.get(i)); } what print last element. hence list1.size() - 1

what regex retrieve value of "token" attribute following json fragment? 259,"possible_flags":["recommending","looking-for"],"id":297,"organisations":[],"showwarning":false,"token":"bf311e7a1a4e49846c0fb836934e7685610829d0","intention":"neighbourhood-nearby"... i want match bf311e7a1a4e49846c0fb836934e7685610829d0 . this code give full text including "token":"___" ("token":"[a-z0-9]*") this give token: "token":("[a-z0-9]*")

i had table called pivot_device_user , had sequence on id not null default nextval('pivot_device_user_id_seq'::regclass) . then decided rename table pivot_box_user , nextval(...) still nextval('pivot_device_user_id_seq'::regclass) . i'd change nextval('pivot_box_user_id_seq'::regclass) . how do this? first must understand serial is: safely , cleanly rename tables use serial primary key columns in postgres? auto increment sql function the column default not stored text literal. see human-readable text representation: nextval('pivot_device_user_id_seq'::regclass) 'pivot_device_user_id_seq'::regclass resolved oid internally ( regclass precise) - oid of underlying sequence - , that's what's stored (early binding). if rename sequence, oid remains unchanged. need rename sequence : alter sequence pivot_device_user_id_seq rename pivot_box_user_id_seq; check success with: select pg_get_serial_sequence('
