Ошибка в Matlab: Caught «std :: exception» Сообщение об ошибке:

Question

Я могу подключиться к серверу, где есть две версии matlab Matlab_R2013a, Matlab_R2012a и другая версия Matlab_R2012b на моем локальном компьютере ubuntu 12.10. За последние несколько недель у меня возникла проблема. Иногда я могу запустить код на своем компьютере, но после того, как это займет много времени, или если я попытаюсь запустить аналогичный код несколько раз, я получаю сообщение об ошибке, и Matlab больше не работает. То же самое происходит и для Matlabs на серверах. Я должен перезапустить, а затем снова запустить Matlab на короткое время, но после этого снова сталкиваюсь с той же проблемой снова и снова.

Ошибка Matlab показ является

Я удалил локальную папку .matlab. Но после этого я снова столкнусь с этой проблемой.

Пожалуйста, помогите мне решить эту проблему в MATLAB. Заранее спасибо.

Проблема была в основном в том, что слишком много файлов были открыты.

Answer 1

У меня возникла аналогичная проблема, и, как утверждает Петеш, проблема с файловым дескриптором - у MATLAB может быть только так много открытых файлов одновременно. Быстрое исправление состоит в том, чтобы сделать fclose all в командном окне MATLAB. Чтобы проверить, сколько файлов у вас открыто, используйте fopen('all'), который отобразит список активных ручек. (Моя версия MATLAB 2013a заполняется в 512 открытых файлах).

Ключ сообщение об ошибке, чтобы выбрать из всех строк ошибок он генерирует является

(Too many open files) 

Лучшее решение, чтобы убедиться, что любые сценарии вы должны закрыть файлы после их открытия, особенно если, скажем, вы каждый раз открывают файлы в цикле.

Answer 2

меня тоже также есть та же самая проблема. закройте все открытые файлы внутри цикла, используя fclose() функцию, чтобы бросить ошибку прочь ... весело M.Santhanakumar

Answer 3

Он должен, потому что вы открыть .txt файла слишком много раз, но не закрывать их своевременно , попробовать это:

fidout = fopen([saveLabel_path, 'new_Label.txt'], 'a'); 
fprintf(fidout, '%s \n', final_label); 
fprintf(fidout, '\n'); 
fclose(fidout); 

, чтобы избежать еще предупреждаю, просто добавьте это: fclose все; Будьте осторожны, потому что вы никогда не увидите эту ошибку еще раз, проститься с ним навсегда ...

жаль, что это может помочь вам ...

Answer 4

Согласно тому, что файлы, которые вы могли бы открывать и не закрывать, использование $ fclose $ в Matlab (например, $ fclose ('myfile') $). Я часто использую $ fclose ('all') $, чтобы убедиться, что я не пропущу ни одного файла :)

Answer 5

Если вы получаете эту ошибку в Matlab, путь является проблемой, предположим, что ur использует любое другое программное обеспечение, как питон Явы,

так и есть, чтобы сделать очистить временный файл в переменном окружении, например

если и видит, как this path in[ C:\Python27\Scripts] в переменной среде и перейти на темп удалить эту ошибку строки будет ясно ,
