cmake missing from setup #2307

Expected Behavior

pip install dlib

Current Behavior

RuntimeError:
*******************************************************************
CMake must be installed to build the following extensions: _dlib_pybind11

Steps to Reproduce

pip install dlib
Catalina 10.15.6

Workaround

pip install cmake
(before pip install dlib)

Suggested fix

Simply include cmake in setup

The text was updated successfully, but these errors were encountered:

dlib’s setup.py used to depend on cmake but two years ago it was removed because the version of cmake installed on some systems was aggressively broken. The result was that people would try to install dlib and pip would «install cmake», resulting in a broken cmake being installed, and IIRC hiding a good working cmake user already had. Resulting in things not working.

Maybe it’s better now. IDK. We can try turning it on again and seeing if the pip copy of cmake has its act together now. I just added the dependency to setup.py. You can try it and see if it works for you. Hopefully no one posts an issue where pip broke their cmake installs.

Ah yes, I hope I’m not the bad guy here. Finger’s crossed.

I may have been bitten by this issue in my build environment (or rather, the reverse, the issue that caused cmake to be removed in the first place).

I’m building a project depending on dlib , which I compile from source, by cloning this repo.

Prior to compiling dlib , I install cmake from ubuntu repos, which get me cmake v3.1.5. This succeeds in compiling dlib , and setuptools processes depdencencies without issue:

However, since this commit from a couple days ago, setuptools attempts to install cmake v3.18.4 when processing dependencies which doesn’t go so well:

If that can help, this error happened to me while compiling dlib on a docker instance running in AWS codebuild, using an image based off Ubuntu 16.04 and using python 3.5.

Почему не получается установить библиотеку dlib?

Хотел установить библиотеки: cmake, dlib, face-recognition, и у меня они при установке выдают ошибку:

В чем может быть проблема? Уже пытался переустанавливать версии питона(сейчас 3.8.0)
+ меня установлен VS2022 с C++ пакетами

You need to install Visual Studio for C++.

Я просмотрел важную штуку: Python 3.8, а glib максимум 3.6 поддерживает.

dlib максимум 3.6 Python поддерживает.
Думаю, правильно будет создать виртуальное окружение (например virtualenv), pycharm это делает особенно удобно; и в нем поставить нужную версию python и остальные нужные библиотеки ставить там же. И там же писать код.

Также со слов Евгений Шатунов надо убедиться, что

должна стоять нагрузка на разработку C++ приложений с использованием cmake.

dlib вроде вполне себе работает и под свежими версиями python. У меня вполне успешно устанавливается и все задачи выполняет:

Im so lost, any response or suggestions will be appreciated so much. Thank you

Solution

You have figured it out yourself, but I wanted to add some remarks on your installation methods:

pip install dlib

As there is only the tar.gz on pypi, it downloads that and then tries to run setup.py after installing the reuqirements

Therefore, you manually doing the tar.gz, extracting it and running python setup.py install is the same thing as the first command and also

python -m pip install  https://files.pythonhosted.org/packages/1e/62/aacb236d21fbd08148b1d517d58a9d80ea31bdcd386d26f21f8b23b1eb28/dlib-19.18.0.tar.gz

Is doing the same in the end, trying to run setup.py to install.

In this case it involves the compilation of c/c++ code which requires for the right compiler/build tools to be installed which pip cannot take care of. It is not built for this task.

I was trying to install dlib library for face recognition in pycharm,

pip install dlib

I’m using virtual environment and base interpreter is C:UsersAyushmanAppDataLocalProgramsPythonPython38-32python.exe

Already installed cmake and pip.

python—version 3.8.3

pip—version 20.1.1

When I tried to install from setting, I got this error message:

Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at 'C:UsersAyushmanPycharmProjectsdemoProjectvenvScriptspython.exe'. 

When I used terminal, I got this error message:

Настройка программного обеспечения

Без промедления начнём. Нам нужно установить следующее ПО:

• Windows 10

• Anaconda 3 (Python 3.8)

• Visual Studio 2019 (Community) — объясню позже, зачем она понадобится.

Открываем Anaconda Prompt (Anaconda3) и устанавливаем следующие пакеты:

pip install opencv-python
pip install dlib
pip install face_recognition

И уже на этом моменте начнутся проблемы с dlib.

Решаем проблему с dlib

Я перепробовал все решения, что нашёл в интернете и они оказались неактуальными — раз, два, три, официальное руководство и видео есть. Поэтому будем собирать пакет вручную.

Итак, первая же ошибка говорит о том, что у нас не установлен cmake.

ERROR: CMake must be installed to build dlib

Не закрывая консоль, вводим следующую команду:

pip install cmake

Проблем при установке быть не должно

Пробуем установить пакет той же командой (pip install dlib), но на этот раз получаем новую ошибку:

Отсутствуют элементы Visual Studio

Ошибка явно указывает, что у меня, скорее всего, стоит студия с элементами только для C# — и она оказывается права. Открываем Visual Studio Installer, выбираем «Изменить», в вкладке «Рабочие нагрузки» в разделе «Классические и мобильные приложения» выбираем пункт «Разработка классических приложений на С++»:

Пошагово

Почему важно оставить все галочки, которые предлагает Visual Studio. У меня с интернетом плоховато, поэтому я решил не скачивать пакет SDK для Windows, на что получил следующую ошибку:

Не нашли компилятор

Я начал искать решение этой ошибки, пробовать менять тип компилятора (cmake -G » Visual Studio 16 2019″), но только стоило установить SDK, как все проблемы ушли.

Я пробовал данный метод на двух ПК и отмечу ещё пару подводных камней. Самое главное — Visual Studio должна быть 2019 года. У меня под рукой был офлайн установщик только 2017 — я мигом его поставил, делаю команду на установку пакета и получаю ошибку, что нужна свежая Microsoft Visual C++ версии 14.0. Вторая проблема была связана с тем, что даже установленная студия не могла скомпилировать проект. Помогла дополнительная установка Visual C++ 2015 Build Tools и Microsoft Build Tools 2015.

Открываем вновь Anaconda Prompt, используем ту же самую команду и ждём, когда соберется проект (около 5 минут):

Сборка

Управляем громкостью

Вариантов оказалось несколько (ссылка), но чем проще — тем лучше. На русском язычном StackOverflow предложили использовать простую библиотеку от Paradoxis — ей и воспользуемся. Чтобы установить её, нам нужно скачать архив, пройти по пути C:ProgramDataAnaconda3Lib и перенести файлы keyboard.py, sound.py из архива. Проблем с использованием не возникало, поэтому идём дальше

Собираем события мыши

Самым популярным модулем для автоматизации управления мышью/клавиатурой оказался pynput. Устанавливаем так же через (pip install dlib). У модуля в целом неплохое описание — https://pynput.readthedocs.io/en/latest/mouse.html . Но у меня возникли сложности при получении событий. Я написал простую функцию:

from pynput import mouse

def func_mouse():
        with mouse.Events() as events:
            for event in events:
                if event:
                    print('Переместил мышку/нажал кнопку/скролл колесиком: {}n'.format(event))
                    print('Делаю половину громкости: ', time.ctime())
                    Sound.volume_set(volum_half)
                    break

В комментариях к статье придём к истине, как лучше сделать.

А что в итоге?

Adam Geitgey, автор библиотеки face recognition, в своём репозитории имеет очень хороший набор примеров, которые многие используют при написании статей: https://github.com/ageitgey/face_recognition/tree/master/examples

Воспользуемся одним из них и получим следующий код, который можно скачать по ссылке: Activity.ipynb, Activity.py

Код

# Подключаем нужные библиотеки
import cv2
import face_recognition
 
# Получаем данные с устройства (веб камера у меня всего одна, поэтому в аргументах 0)
video_capture = cv2.VideoCapture(0)
 
# Инициализируем переменные
face_locations = []

from sound import Sound
Sound.volume_up() # увеличим громкость на 2 единицы
current = Sound.current_volume() # текущая громкость, если кому-то нужно

volum_half=50  # 50% громкость
volum_full=100 # 100% громкость

Sound.volume_max() # выставляем сразу по максимуму


# Работа со временем

# Подключаем модуль для работы со временем
import time
# Подключаем потоки
from threading import Thread
import threading


# Функция для работы с активностью мыши
from pynput import mouse

def func_mouse():
        with mouse.Events() as events:
            for event in events:
                if event == mouse.Events.Scroll or mouse.Events.Click:
                    #print('Переместил мышку/нажал кнопку/скролл колесиком: {}n'.format(event))
                    print('Делаю половину громкости: ', time.ctime())
                    Sound.volume_set(volum_half)
                    break

# Делаем отдельную функцию с напоминанием
def not_find():
    #print("Cкрипт на 15 секунд начинается ", time.ctime())
    print('Делаю 100% громкости: ', time.ctime())
    #Sound.volume_set(volum_full)
    Sound.volume_max()
    
    # Секунды на выполнение
    #local_time = 15
    # Ждём нужное количество секунд, цикл в это время ничего не делает
    #time.sleep(local_time)
    
    # Вызываю функцию поиска действий по мышке
    func_mouse()
    #print("Cкрипт на 15 сек прошел")


# А тут уже основная часть кода

while True:
    ret, frame = video_capture.read()
    
    '''
    # Resize frame of video to 1/2 size for faster face recognition processing
    small_frame = cv2.resize(frame, (0, 0), fx=0.50, fy=0.50)
    rgb_frame = small_frame[:, :, ::-1]
    '''

    rgb_frame = frame[:, :, ::-1]
    
    face_locations = face_recognition.face_locations(rgb_frame)
    
    number_of_face = len(face_locations)
    
    '''
    #print("Я нашел {} лицо(лица) в данном окне".format(number_of_face))
    #print("Я нашел {} лицо(лица) в данном окне".format(len(face_locations)))
    '''
    
    if number_of_face < 1:
        print("Я не нашел лицо/лица в данном окне, начинаю работу:", time.ctime())
        '''
        th = Thread(target=not_find, args=()) # Создаём новый поток
        th.start() # И запускаем его
        # Пока работает поток, выведем на экран через 10 секунд, что основной цикл в работе
        '''
        #time.sleep(5)
        print("Поток мыши заработал в основном цикле: ", time.ctime())
        
        #thread = threading.Timer(60, not_find)
        #thread.start()
        
        not_find()
        '''
        thread = threading.Timer(60, func_mouse)
        thread.start()
        print("Поток мыши заработал.n")
        # Пока работает поток, выведем на экран через 10 секунд, что основной цикл в работе
        '''
        #time.sleep(10)
        print("Пока поток работает, основной цикл поиска лица в работе.n")
    else:
        #все хорошо, за ПК кто-то есть
        print("Я нашел лицо/лица в данном окне в", time.ctime())
        Sound.volume_set(volum_half)
        
    for top, right, bottom, left in face_locations:
        cv2.rectangle(frame, (left, top), (right, bottom), (0, 0, 255), 2)
    
    cv2.imshow('Video', frame)
    
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break


video_capture.release()
cv2.destroyAllWindows()

Суть кода предельно проста: бегаем в цикле, как только появилось хотя бы одно лицо (а точнее координаты), то звук делаем 50%. Если не нашёл никого поблизости, то запускаем цикл с мышкой.

Тестирование в бою

Ожидание и реальность

Если вы посмотрели видео, то поняли, что результат ещё далёк от реальной эксплуатации.

Признаю честно — до этого момента никогда не сталкивался с многопоточностью на Python, поэтому «с наскоку» тему взять не удалось и результат по видео понятен. Есть неплохая статья на Хабре, описывающая различные методы многопоточности, применяемые в языке. Пока у меня решения нету по этой теме нету — будет повод разобраться лучше и дописать код/статью с учетом этого.

Так же возникает закономерный вопрос — а если вместо живого человека поставить перед монитором картинку? Да, она распознает, что, скорее всего, не совсем верно. Мне попался очень хороший материал по поводу определения живого лица в реальном времени — https://www.machinelearningmastery.ru/real-time-face-liveness-detection-with-python-keras-and-opencv-c35dc70dafd3/ , но это уже немного другой уровень и думаю новичкам это будет посложнее. Но эксперименты с нейронными сетями я чуть позже повторю, чтобы тоже проверить верность и повторяемость данного руководства.

Немаловажным фактором на качество распознавания оказывает получаемое изображение с веб-камеры. Предложение использовать 1/4 изображения (сжатие его) приводит только к ухудшению — моё лицо алгоритм распознать так и не смог. Для повышения качества предлагают использовать MTCNN face detector (пример использования), либо что-нибудь посложнее из абзаца выше.

Другая интересная особенность — таймеры в Питоне. Я, опять же, признаю, что ни разу до этого не было нужды в них, но все статьях сводится к тому, чтобы ставить поток в sleep(кол-во секунд). А если мне нужно сделать так, чтобы основной поток был в работе, а по истечению n-ое количества секунд не было активности, то выполнялась моя функция? Использовать демонов (daemon)? Так это не совсем то, что нужно. Писать отдельную программу, которая взаимодействует с другой? Возможно, но единство программы пропадает.

Заключение

На своём примере могу точно сказать — не все руководства одинаково полезны и простая задача может перерасти в сложную. Я понимаю, что большинство материалов является переводом/простым копированием документации. Но если ты пишешь руководство, то проверь хотя бы на тестовой системе, что написанные тобой действия точно повторимы. Пробуйте, экспериментируйте — это хороший повод изучить и узнать новое.

P.S. Предлагаю вам, читатели, обсудить в комментариях статью — ваши идеи, замечания, уточнения.
