  • Memory allocation problem with SVMs in OpenCV

    - by worksintheory
    Hi, I've been using OpenCV happily for a while, but now I have a problem which has bugged me for quite some time. The following code is reasonably minimal example of my problem: #include <cv.h> #include <ml.h> using namespace cv; int main(int argc, char **argv) { int sampleCountForTesting = 2731; //BROKEN: Breaks svm.train_auto(...) for values of 2731 or greater! Mat trainingData( sampleCountForTesting, 1, CV_32FC1, Scalar::all(0.0) ); Mat trainingResponses( sampleCountForTesting, 1, CV_32FC1, Scalar::all(0.0) ); for(int j = 0; j < 6; j++) { trainingData.at<float>( j, 0 ) = (float) (j%2); trainingResponses.at<float>( j, 0 ) = (float) (j%2); //Setting a few values so I don't get a "single class" error } CvSVMParams svmParams( 100, //100 is CvSVM::C_SVC, 2, //2 is CvSVM::RBF, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, NULL, TermCriteria( TermCriteria::MAX_ITER | TermCriteria::EPS, 2, 1.0 ) ); CvSVM svm = CvSVM(); svm.train_auto( trainingData, trainingResponses, Mat(), Mat(), svmParams ); return 0; } I just create matrices to hold the training data and responses, then set a few entries to some value other than zero, then run the SVM. But it breaks whenever there are 2731 rows or more: OpenCV Error: One of arguments' values is out of range (requested size is negative or too big) in cvMemStorageAlloc, file [omitted]/opencv/OpenCV-2.2.0/modules/core/src/datastructs.cpp, line 332 With fewer rows, it seems to be fine and a classifier trained in a similar manner to the above seems to be giving reasonable output. Am I doing something wrong? I'm pretty sure it's not actually anything to do with lack of memory, as I've got 6GB and also the code works fine when the data has 2730 rows and 10000 columns, which is a much bigger allocation. I'm running OpenCV 2.2 on OSX 10.6 and initially I thought the problem might be related to this bug if for some reason the fix wasn't included in the MacPorts version. Now I've also tried downloading the most recent stable version from the OpenCV site and building with cmake and using that, but I still get the same error, and the fix is definitely included in that version. Any help would be much appreciated! Thanks,

  • java httpclient post

    - by Eric V
    Hi, I have a question about how to allow my jsp page to issue a post command to the server, and still have the browser fallow the re direction of the posted page. Here are the code snipets: code that does the post (this is inside a jsp file): HttpClient client = new DefaultHttpClient(); client.getParams().setParameter("SUBMITTED", "submitted"); client.getParams().setParameter("xxxxxxxx", purchaser.getemail()); client.getParams().setParameter("xxxxxxxx", purchaser.getsuject()); HttpPost method = new HttpPost(url+"process.jsp"); client.execute(method); here is a snipet of process.jsp if (person.getStatus() == person.ACTIVE) response.sendRedirect("Account.jsp); else if (person.getStatus() == person.ERROR) response.sendRedirect("Error.jsp); I would like the browser to the fallow/goto the redirect from the process.jsp. Does anyone know a tutorial that would help me or Am I going about this the wrong way. Thanks, eric

  • RegisterClientScriptBlock code not executing.

    - by ProfK
    I'm using the following code in an attempt to show a dialog with a list of errors on the client: if (rollout.ImportErrors.Count > 0) { ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true); } The error count is non-zero and the following script block is emitted, but the script isn't executing. <script type="text/javascript"> //<![CDATA[ $("#error-report").dialog("open")//]]> </script> If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. What am I doing wrong? BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.

  • Setup Padrino with DataMapper and MySQL database

    - by Ivo Sabev
    Hello I am trying to setup a Padrino project using DataMapper and MySQL on my Mac OSX Snow Leopard. I have the necessary gems: dm-core data_objects do_mysql mysql (linked to my original Mac OSX installation) But when I try to start the padrino with PADRINO START from the console, I get the following error: /Users/ivolution/.bundle/ruby/1.9.1/gems/dm-core-0.10.2/lib/dm-core/adapters/mysql_adapter.rb:3:in `require': no such file to load -- do_mysql (LoadError) But as I said I do have do_mysql gem installed so there shouldn't be such error, I did bundle install in my project folder before trying to start Padrino. Any ideas?

  • Images missing after moving Django to new server

    - by miszczu
    I'm moving Django project to new server. I'm newbie in Django, and I don't know where should be upload folder. There are all images which should be displayed on website. In config file I haven't seen upload folder I could specify, so I'm guessing it always should be the same location for django projects or I just can't find it. Locations are saved in database. When I've put uploaded files into media folder, so url was like domain.co.uk/media/upload/media/images/year/month/day/image_name.ext and the same is on the old website, images on website ware still missing. All images are visible if I put url by hand, but django doesn't seems to see files. Also I check django log file: 2012-05-30 09:13:33,393 ERROR render: Thumbnail tag failed: [in /usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py (line 49)] Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 45, in render return self._render(context) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 97, in _render file_, geometry, **options File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/base.py", line 50, in get_thumbnail cached = default.kvstore.get(thumbnail) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 25, in get return self._get(image_file.key) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 123, in _get value = self._get_raw(add_prefix(key, identity)) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/cached_db_kvstore.py", line 26, in _get_raw value = KVStoreModel.objects.get(key=key).value File "/usr/lib/python2.6/site-packages/django/db/models/manager.py", line 132, in get return self.get_query_set().get(*args, **kwargs) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 344, in get num = len(clone) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 82, in __len__ self._result_cache = list(self.iterator()) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 273, in iterator for row in compiler.results_iter(): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 680, in results_iter for rows in self.execute_sql(MULTI): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 735, in execute_sql cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/util.py", line 34, in execute return self.cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 86, in execute return self.cursor.execute(query, args) File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 174, in execute self.errorhandler(self, exc, value) File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue DatabaseError: (1146, "Table 'thumbnail_kvstore' doesn't exist") 2012-05-30 09:13:33,396 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = office-closed-message ); args=(True, u'office-closed-message') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,399 DEBUG execute: (0.000) SELECT `menus_menu`.`id`, `menus_menu`.`name`, `menus_menu`.`slug`, `menus_menu`.`base_url`, `menus_menu`.`description`, `menus_menu`.`enabled` FROM `menus_menu` WHERE (`menus_menu`.`enabled` = True AND `menus_menu`.`slug` = about ); args=(True, u'about') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,401 DEBUG execute: (0.000) SELECT `menus_menuitem`.`id`, `menus_menuitem`.`menu_id`, `menus_menuitem`.`title`, `menus_menuitem`.`url`, `menus_menuitem`.`order` FROM `menus_menuitem` INNER JOIN `menus_menu` ON (`menus_menuitem`.`menu_id` = `menus_menu`.`id`) WHERE `menus_menu`.`slug` = about ORDER BY `menus_menuitem`.`order` ASC; args=(u'about',) [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,404 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = contactdetails-footer ); args=(True, u'contactdetails-footer') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] I checked database and there is no table calls thumbnail_kvstore, but I have database backup, and in backup files this table doesn't exist.

  • PHP SASL(PECL) sasl_server_init(app) works with CLI but not with ApacheModule

    - by ZokRadonh
    I have written a simple auth script so that Webusers can type in their username and password and my PHP script verifies them by SASL. The SASL Library is initialized by php function sasl_server_init("phpfoo"). So phpfoo.conf in /etc/sasl2/ is used. phpfoo.conf: pwcheck_method: saslauthd mech_list: PLAIN LOGIN log_level: 9 So the SASL library now tries to connect to saslauthd process by socket. saslauthd command line looks like this: /usr/sbin/saslauthd -r -V -a pam -n 5 So saslauthd uses PAM to authenticate. In the php script I have created sasl connection by sasl_server_new("php", null, "myRealm"); The first argument is the servicename. So PAM uses the file /etc/pam.d/php to see for further authentication information. /etc/pam.d/php: auth required pam_mysql.so try_first_pass=0 config_file=/etc/pam.d/mysqlconf.nss account required pam_permit.so session required pam_permit.so mysqlconf.nss has all information that is needed for a useful MySQL Query to user table. All of this works perfectly when I run the script by command line. php ssasl.php But when I call the same script via webbrowser(php apache module) I get an -20 return code (SASL_NOUSER). In /var/log/messages there is May 18 15:27:12 hostname httpd2-prefork: unable to open Berkeley db /etc/sasldb2: No such file or directory I do not have anything with a Berkeley db for authentication with SASL. I think authentication using /etc/sasldb2 is the default setting. In my opinion it does not read my phpfoo.conf file. For some reason the php-apache-module ignores the parameter in sasl_server_init("phpfoo"). My first thought was that there is a permission issue. So back in shell: su -s /bin/bash wwwrun php ssasl.php "Authentication successful". - No file-permission issue. In the source of the sasl-php-extension we can find: PHP_FUNCTION(sasl_server_init) { char *name; int name_len; if (zend_parse_parameters(1 TSRMLS_CC, "s", &name, &name_len) == FAILURE) { return; } if (sasl_server_init(NULL, name) != SASL_OK) { RETURN_FALSE; } RETURN_TRUE; } This is a simple pass through of the string. Are there any differences between the PHP CLI and PHP ApacheModule version that I am not aware of? Anyway, there are some interesting log entries when I run PHP in CLI mode: May 18 15:44:48 hostname php: SQL engine 'mysql' not supported May 18 15:44:48 hostname php: auxpropfunc error no mechanism available May 18 15:44:48 hostname php: _sasl_plugin_load failed on sasl_auxprop_plug_init for plugin: sqlite May 18 15:44:48 hostname php: sql_select option missing May 18 15:44:48 hostname php: auxpropfunc error no mechanism available May 18 15:44:48 hostname php: _sasl_plugin_load failed on sasl_auxprop_plug_init for plugin: sql Those lines are followed by lines of saslauthd and PAM which results in authentication success.(I do not get any of them in ApacheModule mode) Looks like that he is trying auxprop pwcheck before saslauthd. I have no other .conf file in /etc/sasl2. When I change the parameter of sasl_server_init to something other then I get the same error in CLI mode as in ApacheModule mode.

  • Problem with Twitter basic authentication using AJAX

    - by jelford
    I'm developing a javascript App that needs, as part of its functionality, for users to be able to update their Twitter status. The App is designed to work on mobiles, and as such I don't really want to be sending users all the way over to the Twitter site to sign in; they should just be able to pass their credentials to the app, and I'll handle all the signin. So I'm trying to use the Basic Auth with the restful API. My code looks like: function postTweet(input){ $.ajax( { type: "POST", url: "http://twitter.com/statuses/update.json", data: {status: input}, dataType: "json", error: function() { alert("Some error occured"); }, success: function() { alert("Success!"); }, beforeSend: function(request) { request.setRequestHeader("Authorization", "Basic BASE64OFMYCREDENTIALS");} } ) ; } So, as far as I'm aware, this should perform the authentication from the XMLHttpRequest header, and then post the status. However, whenever I call this code, I get a "401 Unauthorized" error from Twitter. Below are the request & response headers from firebug: Request: OPTIONS /statuses/update.json HTTP/1.1 Host: twitter.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.2) Gecko/20100115 Firefox/3.6 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-gb,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Origin: null Access-Control-Request-Method: POST Access-Control-Request-Headers: authorization Response: HTTP/1.1 401 Unauthorized Date: Sat, 13 Mar 2010 11:08:58 GMT Server: hi Status: 401 Unauthorized WWW-Authenticate: Basic realm="Twitter API" X-Runtime: 0.00204 Content-Type: application/json; charset=utf-8 Cache-Control: no-cache, max-age=300 Set-Cookie: guest_id=1268478538488; path=/ _twitter_sess=BAh7CDoPY3JlYXRlZF9hdGwrCPlyNlcnAToHaWQiJWUyN2YzYjc3OTk2NGQ3%250ANzJkYTA4MjYzOWJmYTQyYmUyIgpmbGFzaElDOidBY3Rpb25Db250cm9sbGVy%250AOjpGbGFzaDo6Rmxhc2hIYXNoewAGOgpAdXNlZHsA--d687808459872da0aa6a89cab35fd347300b4d07; domain=.twitter.com; path=/ Expires: Sat, 13 Mar 2010 11:13:58 GMT Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 88 Connection: close Any help with this would be much appreciated, Thanks, jelford ps.

  • swfobject in Uploadify not working with IE 7 or 8

    - by Graeme
    I am using Uploadify and have a pop up which is loaded by jQuery by Ajax. The page on which the popup lives on has an include to swfobject (from Google's Code Api) and the Uploadify button should appear. This works great on FF and Chrome but IE gives me a javascript error Unknown runtime error line 4 character 5942 Anyone got any ideas how to fix this problem? It's possibly to do with the fact that I'm using it from within dynamic content. I found the following link but there is no definitive answer Possible answer

  • Django-pyodbc SQL Server/freetds server connection problems on linux

    - by wizard
    Error: ('IM002', '[IM002] [unixODBC][Driver Manager]Data source name not found, and no default driver specified (0) (SQLDriverConnectW)') I'm migrating from developing on a windows development machine to Linux machine in production and I'm having issues with the freetds driver. As far as I can tell that error message means it can't find the driver. I can connect via the cli via sqsh and tsql. I've setup my settings.py as such. 'bc2db': { 'ENGINE': 'sql_server.pyodbc', 'NAME': 'DataTEST', 'USER': 'appuser', 'PASSWORD': 'PASS', 'HOST': 'bc2.domain.com', 'options': { 'driver': 'FreeTDS', } }, Does anyone have any SQL Server experience with django? do I have to use a dns? (how would I format that?)

  • CacheManager.getCacheFileBaseDir() always returns null

    - by Leon
    Hi, I've been trying to use the CacheManager for caching some http requests but it failed every time with a nullpointer exception. After some digging I believe I found out why: CacheManager.getCacheFileBaseDir() always returns null so when I try to use CacheManager.getCacheFile() or CacheManager.saveCacheFile() they fail. CacheManager.cacheDisabled() returns false :S I hadn 't created a cache partition via the AVD manager so I thought the problem lie there. But after creating a cache partition getCacheFile() still return null: 03-16 00:25:16.321: ERROR/AndroidRuntime(296): Caused by: java.lang.NullPointerException 03-16 00:25:16.321: ERROR/AndroidRuntime(296): at android.webkit.CacheManager.getCacheFile(CacheManager.java:296) What could be the problem? I've got the code posted here: http://pastebin.com/eaJwfXEK But it's a bit messy because I've been trying tons of stuff. Why does CacheManager.getCacheFileBaseDir() return null and not a File object? Thanks in advance! Leon

  • get local groups and not the primary groups for a domain user

    - by user175084
    i have a code to get the groups a user belongs to. try { DirectoryEntry adRoot = new DirectoryEntry(string.Format("WinNT://{0}", Environment.UserDomainName)); DirectoryEntry user = adRoot.Children.Find(completeUserName, "User"); object obGroups = user.Invoke("Groups"); foreach (object ob in (IEnumerable)obGroups) { // Create object for each group. DirectoryEntry obGpEntry = new DirectoryEntry(ob); listOfMyWindowsGroups.Add(obGpEntry.Name); } return true; } catch (Exception ex) { new GUIUtility().LogMessageToFile("Error in getting User MachineGroups = " + ex); return false; } the above code works fine when i have to find the groups of a local user but for a domain user it returns a value "Domain User" which is kind of wierd as it is a part of 2 local groups. Please can some1 help in solving this mystery. thanks Research I did some finding and got that i am being returned the primary group of the domain user called "Domain User" group but what i actually want is the groups of the local machines the domain user is a part of... i cannot get that.. any suggestions another code using LDAP string domain = Environment.UserDomainName; DirectoryEntry DE = new DirectoryEntry("LDAP://" + domain, null, null, AuthenticationTypes.Secure); DirectorySearcher search = new DirectorySearcher(); search.SearchRoot = DE; search.Filter = "(SAMAccountName=" + completeUserName + ")"; //Searches active directory for the login name search.PropertiesToLoad.Add("displayName"); // Once found, get a list of Groups try { SearchResult result = search.FindOne(); // Grab the records and assign them to result if (result != null) { DirectoryEntry theUser = result.GetDirectoryEntry(); theUser.RefreshCache(new string[] { "tokenGroups" }); foreach (byte[] resultBytes in theUser.Properties["tokenGroups"]) { System.Security.Principal.SecurityIdentifier mySID = new System.Security.Principal.SecurityIdentifier(resultBytes, 0); DirectorySearcher sidSearcher = new DirectorySearcher(); sidSearcher.SearchRoot = DE; sidSearcher.Filter = "(objectSid=" + mySID.Value + ")"; sidSearcher.PropertiesToLoad.Add("distinguishedName"); SearchResult sidResult = sidSearcher.FindOne(); if (sidResult != null) { listOfMyWindowsGroups.Add((string)sidResult.Properties["distinguishedName"][0]); } } } else { new GUIUtility().LogMessageToFile("no user found"); } return true; } catch (Exception ex) { new GUIUtility().LogMessageToFile("Error obtaining group names: " + ex.Message + " Please contact your administrator."); // If an error occurs report it to the user. return false; } this works too but i get the same result "Domain Users" . Please can some1 tell me how to get the local machine groups...????

  • Help installing Zorba (XQUERY) PHP Extension on windows

    - by Davey
    Hi, I'm trying to install zorba php extension on windows and I am having all sorts of problems. I have installed the zorba binaries on my computer, but when I try to install the PECL package (pecl install zorba-alpha) I get the following error "ERROR: the DSP zorba.dsp does not exist". I've tried searching for zorba_api.dll or zorba_api.so in order to just bypass the pecl install process, but no luck. If anyone can tell me how to get the zorba extension installed on my windows php I will be eternally grateful. Alternately, if someone knows of another xquery solution for PHP that I can install, I will be equally excited and appreciative. Thank you! Davey

  • PostSharp , PDB Debugging and Referenced Assemblies ...

    - by Anil Bisnoi
    When using PostSharp with a Referenced Assembly with proper PDB info( checked with chkmatch), it seems strange that the debug info gets lost by VStudio build and post compile process and I get the following error by using chkmatch to compare the assembly after the vstudio build. Error: Debug information not found in the executable. So it doesn't step into for debugging into this assembly. Does Post Sharp properly writes back the Assemblies without destroying the PDB location offset info as I saw no valid offset info in the written back into DLL by PostSharp using Hex Editor and What's the workaround for this ? Thx Anil Bisnoi
