Seeing a similar issue to #432 with opencv-python==4.6.0.66 packaged using pyinstaller==4.4. It works fine when running from source; the issue only occurs when packaged. opencv-python==4.5.5.64 works fine.

My Env:
Ubuntu 16
Python3.8
opencv-python==4.6.0.66
pyinstaller==4.4

@SeungjunNah

Same here. I also had to revert to 4.5.5.64

@asenyaev

Hi @mrjeckel, @SeungjunNah!

I’ve tried to reproduce the issue on my Ubuntu 18.04 installing Python3.8, opencv-python==4.6.0.66 and pyinstaller==4.4, but anything passed successfully.

My reproducing steps:

  1. Install opencv-python==4.6.0.66:
python3.8 -m pip install --force-reinstall --no-cache opencv-python==4.6.0.66
  1. Install pyinstaller==4.4:
python3.8 -m pip install --force-reinstall --no-cache pyinstaller==4.4
  1. Create py script:

test.py

import cv2

if __name__ == '__main__':
    print("Hello, world!")
  1. Use pyinstaller with this script:
pyinstaller --onefile test.py

@asenyaev

It can be something wrong with a local environment on your side. Could you check which OpenCV Python packages were installed using pip:

python3.8 -m pip list | grep -i opencv

Multiple OpenCV Python packages can break your environment. Please, use only one package at a time. In addition, I would suggest to use --force-reinstall flag for pip to be sure that re-installation happened.

@noword

I use Windows 10, python 3.8, newest version of opencv-python. When I try to pack a exe with pyinstaller, I have the exact same problem. opencv-python==4.5.5.64 works fine.

I compared two version of init.py
Maybe the key is in line 162:
4.5.5.64: native_module = importlib.import_module(«cv2.cv2»)
4.6.0.66: native_module = importlib.import_module(«cv2»)

@AeonDave

Environment:

Windows 10

PyInstaller: 5.2

Python: 3.10.5

opencv-python 4.6.0.66

Problem:

I am trying to compile my Python code with PyInstaller. The exe is created and when I execute it, I get this error message:

ImportError: ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.

What did I try:

  • I deactivated my Antivirus.
    It didn’t work

I think I tried it all:

  • I installed the previous version of OpenCV:

    pip install opencv-python==4.5.3.56

It didn’t work

  • I installed the latest version:

    pip install —upgrade opencv-python
    pip install —upgrade pyinstaller

It didn’t work

  • I tried to force the reinstallation:

    pip3 install opencv-python —upgrade —force-reinstall

It didn’t work

  • I added the path of cv2:

    pyinstaller —onefile -F —uac-admin —icon=»icon_PhoneBot_256.ico» —clean —noconsole —collect-data pyshadow —paths=»C:UsersgauthAppDataLocalProgramsPythonPython310Libsite-packagescv2″ Project.py

It didn’t work

I have the same problem! How to fix it?

@asmorkalov

@MarioPonce2910

Same here. I also had to revert to 4.5.5.64

Work for me ! Thx

@thucungcuatoi

#680 (comment)

4.5.5.64
I have same this issue and try reinstall opencv-python 4.5.5.64! It’s OK

@samuller

@asenyaev You didn’t show the result of running the executable? The exception doesn’t happen during the pyInstaller creation step, but only when the resulting executable is run, e.g. ./dist/test (or ./dist/test/test when --onefile isn’t used). I hope that’s the difference.

@asmorkalov I just quickly tried the code change used in the MR fix for #689 (i.e. https://github.com/opencv/opencv/pull/22269/files), but it didn’t make a difference to this issue on my local system. I might’ve made some mistake, but I suspect the iPython recursion issue might be different from this pyInstaller issue, and might not be fixed by that MR.

However, it looks like pyInstaller is aware of the issue, and they might have a fix on their side in an upcoming version: pyinstaller/pyinstaller#6964 (comment)

@Neizvestnyj

Same error. opencv-python==4.5.5.64 works

@Alexandro1112

commands

pip3 uninstall opencv-python==4.7.0.68

and

pip3 install -U opencv-python==4.5.3.56

successful installed OpenCV.

#196 CsvToBean parse empty lines error

Situation as the attachments.
I use CSVReader with ColumnPositionMappingStrategy readed the first 7 lines, then use CsvToBean to parse the left part. code like this:

Both of them throw RunTimeException «Error capturing CSV header!» .
After looking up the source code, i found reason at ColumnPositionMappingStrategy.java line 72(version 4.5)

String[] firstLine = reader.peek();// return null

Is this a bug ?
I think when encounter an empty line, csvToBean.parse() return null could be nicer

Discussion

Could you please send me your CSV file, the java class with your ReconRepayTempInfoDO and a small sample program that gets the error that you are seeing because I cannot recreate the error you are experiencing.

By default you the CsvToBean creates a HeaderColumnNameMappingStrategy and it requires that your first line be the header and the header matches fields in the object. If so then one of the two fields in your first line does not exist in your ReconRepayTempInfoDO object and that would give you an error capturing CSV Header message. But that said if I see your full test program I can see where you overrode with a ColumnPositionMappingStrategy and can come up with a test that matches it.

Also with the default HeaderColumnNameMappingStrategy you will get an error on your last line because you have more fields than you do with your header. But that error would be «Caused by: com.opencsv.exceptions.CsvRequiredFieldEmptyException: Number of data fields does not match number of headers.» and that is on purpose!

The other thing is that the skipLines will not skip the header it should skip the line after the header. But there again I am using the default CsvToBean.

Here is the test I added to CsvToBeanTest. If you can modify it to reproduce your result that would be awesome!!

Notice I have the .withThrowsException(false) commented out. With that uncommented out it would not throw an exception with the third data line (the one with more fields) but instead just skip it. So with throws exception as false and skip line as 1 I get back two data lines and with skip lines removed I get three.

. Reading what you are saying it sounds line you are using a CSVReader to read the first seven lines of the file and then pass the same reader (without closing it) into the CsvToBeanBuilder. Is that correct? If so your line 8 must be the Header (all the fields must match what is in the ReconRepayTempInfoDO. I will try and modify my test and see what happens but I will say if true that is the first time I have seen a csv file formatted this way.

ImportError: ERROR: recursion is detected during loading of «cv2» binary extensions. Check OpenCV installation. #680

Seeing a similar issue to #432 with opencv-python==4.6.0.66 packaged using pyinstaller==4.4. It works fine when running from source; the issue only occurs when packaged. opencv-python==4.5.5.64 works fine.

My Env:
Ubuntu 16
Python3.8
opencv-python==4.6.0.66
pyinstaller==4.4

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

Same here. I also had to revert to 4.5.5.64

I’ve tried to reproduce the issue on my Ubuntu 18.04 installing Python3.8 , opencv-python==4.6.0.66 and pyinstaller==4.4 , but anything passed successfully.

My reproducing steps:

  1. Use pyinstaller with this script:

I also tried to do the same steps in a container with Ubuntu 16, and it also finished successfully.

Output Ubuntu 16

It can be something wrong with a local environment on your side. Could you check which OpenCV Python packages were installed using pip :

Multiple OpenCV Python packages can break your environment. Please, use only one package at a time. In addition, I would suggest to use —force-reinstall flag for pip to be sure that re-installation happened.

I use Windows 10, python 3.8, newest version of opencv-python. When I try to pack a exe with pyinstaller, I have the exact same problem. opencv-python==4.5.5.64 works fine.

I compared two version of init.py
Maybe the key is in line 162:
4.5.5.64: native_module = importlib.import_module(«cv2.cv2»)
4.6.0.66: native_module = importlib.import_module(«cv2»)

I have the same problem
however it only appears if I run my python project in trace mode
python 3.8
opencv-contrib-python 4.6.0.66

python3 -u -m trace -c run.py

otherwise it works normally

Same problem on Windows 11 with Python 3.10.2, numpy==1.23.1, pyinstaller==5.2 and opencv-python==4.6.0.66

Problem:

I am trying to compile my Python code with PyInstaller. The exe is created and when I execute it, I get this error message:

What did I try:

  • I deactivated my Antivirus.
    It didn’t work

I think I tried it all:

I installed the previous version of OpenCV:

pip install opencv-python==4.5.3.56

I installed the latest version:

pip install —upgrade opencv-python
pip install —upgrade pyinstaller

I tried to force the reinstallation:

pip3 install opencv-python —upgrade —force-reinstall

I added the path of cv2:

pyinstaller —onefile -F —uac-admin —icon=»icon_PhoneBot_256.ico» —clean —noconsole —collect-data pyshadow —paths=»C:UsersgauthAppDataLocalProgramsPythonPython310Libsite-packagescv2″ Project.py

Here are the logs of PyInstaller if it can help:

Is there anyone who has any idea how to fix this issue?

OpenCV в Python: Часть 1 — Работа с изображениями и видео

Добро пожаловать! Перед вами первая статья из серии OpenCV в Python, которая, как вы уже догадались по названию, посвящена тому, как научиться комфортно работать в OpenCV.

Я понимаю, что у каждого свой стиль обучения, но я настоятельно рекомендую вам вместе со мной следовать за мыслью и писать код по мере прохождения уроков. Все файлы кода и данных будут доступны в конце каждой статьи. Если у вас будут появляться вопросы, не стесняйтесь их задавать.

Не будем терять времени, начнем!

Начало работы с OpenCV

Поскольку мы начинаем с самого начала, в этом разделе мы поговорим об основах обработки изображений. Чтобы начать работать с OpenCV, надо сначала ее установить. Для этого введите команду в терминале (на Windows):

Как только установка будет завершена, можно начинать писать код.

Для начала давайте импортируем необходимые библиотеки.

Модуль cv2 – это и есть OpenCV. Его мы будем использовать для анализа изображений и видео. Модуль argparse будет полезен при работе с аргументами, передаваемыми через терминал. Если вам неудобно работать с командой строкой, можете почитать это руководство (https://www.pyimagesearch.com/2018/03/12/python-argparse-command-line-arguments/), в котором все очень хорошо объясняется.

Работать мы будем с этим изображением.

Разместите это изображение (или любое другое на выбор) в директорию, где находится ваш файл с программой.

В терминале мы передадим это изображение в качестве аргумента, поэтому в файле с исходным кодом нужно сделать парсер аргументов.

После создания экземпляра argparse , добавим аргумент, который, по сути, сообщает, что изображение передается, как аргумент, и его нужно распарсить. Затем обработанный аргумент передается функции vars() , которая возвращает атрибут dict указанного объекта.

С помощью метода imread из cv2, мы положим изображение в переменную image .

Первый аргумент, передаваемый функции – это args[“image”] , обработанный аргумент, содержащий путь к изображению. Поскольку мы сохранили изображение в той же папке, просто передадим имя файла изображения.

Второй аргумент конвертирует изображение в оттенки серого. Этот шаг мы будем часто выполнять при работе с изображениями и видео, потому что обработка цветных изображений намного сложнее и занимает много времени, тогда как зачастую изображений в оттенках серого вполне достаточно для многих задач. Следовательно, нам нет необходимости использовать более сложные и трудные в обработке цветные изображения.

Для отображения изображений используется метод imshow. Первый аргумент – заголовок отображаемого изображения, а второй – сама переменная изображения.

cv2.waitKey(0) будет ждать, пока пользователь не нажмет любую клавишу, после чего окно с изображением закроется.

Помимо вывода самого изображения, эту переменную image можно использовать для отображения некоторой базовой информации, такой как высота и ширина изображения.

OpenCV позволяет сохранить этот файл и записать его на диск. Что интересно, OpenCV также под капотом обрабатывает преобразование типов, то есть вы можете сохранить изначально .jpeg файл в формате .png.

Метод imwrite принимает путь к выходному изображению, которое будет сохранено в качестве первого аргумента, и переменную с изображением в качестве второго. Если вы хотите изменить тип файла, просто измените его в имени пути, а OpenCV позаботится об остальном.

А вот и полный код:

Команда для выполнения файла:

Примечание: Я назвал файл с программой app.py, а файл с изображением photo_one.jpeg, не забудьте вставить свои названия.

После выполнения этого файла, вы получите исходное изображение в оттенках серого:

В вашем основном каталоге создастся папка с изображениями, в которой вы увидите то же изображение, что и в файле newimage.png.

Работа с видео в OpenCV

Теперь, когда мы закончили с изображениями, пришло время познакомиться с основами взаимодействия с веб-камерой или видеофайлами в OpenCV. Работа с видео мало чем отличается от работы с изображениями, поскольку видео состоит из кадров, которые по сути являются изображениями.

Для начала импортируем библиотеки.

Теперь создадим объект VideoCapture , чтобы, как следует из названия, «захватывать» видео.

Число, которое мы передаем, означает источник. 0 – первая веб-камера в вашей системе, 1 – вторая и т.д.

Если вы хотите загрузить уже существующий видеофайл вместо захвата прямой трансляции, просто на место номера вставьте путь к нему.

Затем создадим цикл while , чтобы получать из источника кадр за кадром.

Функция cap.read() возвращает логическое значение (True/False) и кадр. Если кадр был считан верно, то возвращается True.

cv2.imshow() используется для отображения видео. Название видео будет первым аргументом.

Поскольку мы сделали бесконечный цикл, нам нужно что-то, что его прервет.

Поначалу этот фрагмент кода может показаться странным, но как только вы разберетесь в деталях, станет легче.

Функция waitKey(0) возвращает -1, когда ввод вообще не производится. Как только происходит событие, то есть нажимается кнопка, она возвращает 32-разрядное целое число.

В этом сценарии 0xFF – это 8-битный двоичный код 11111111, поскольку для представления символа «q». В результате вы получите целое число меньшее 255.

Следовательно, сравнивая целое число со значением ord(char) , мы можем проверить событие нажатия клавиши и прервать цикл[1].

После того, как мы закончим использовать камеру, ее нужно «освободить». Если мы этого не сделаем, то в следующий раз при попытке ее использовать, вы получите ошибку.

Теперь пришло время запустить файл. На всякий случай, если вы не проследили, приведу весь код этого раздела:

После выполнения файла, вы увидите изображение с веб-камеры в окне под названием «video feed». Чтобы закрыть окно, нажмите «q».

Помните, как мы преобразовали наше цветное изображение в оттенки серого и сохранили его на диске? То же самое можно сделать и с видео. Нужно просто внести несколько незначительных изменений.

В цикл while добавьте следующие инструкции:

После сохранения и выполнения файла вы получите два окна:

Версию в оттенках серого.

Теперь мы можем выводить два или более окон, когда хотим сравнить наши изменения с исходным файлом/потоком. Так проще обнаруживать изменения, которые мы внесли.

Также мы можем сохранить файл с помощью объекта VideoWriter . Перед этим нужно указать переменную fourcc (https://en.wikipedia.org/wiki/FourCC). FourCC – это 4-байтовый код, который используется для указания видеокодека. Полный список кодов можно посмотреть в кодеках FourCC (http://www.fourcc.org/codecs.php).

Имя выходного файла будет первым аргументом. Затем нужно передать количество кадров в секунду (fps) и размер кадра.

Чтобы сохранить видео, нужно записать каждый кадр в цикле while.

Не забудьте в конце освободить экземпляр VideoWriter .

После выполнения этого кода вы заметите, что видео с именем «output.avi» будет присутствовать в вашем главном каталоге. Вот видео, которое мы только что записали и сохранили на диск.

Итоги

В этой статье мы поговорили о самом простейшем – загрузке и записи мультимедийного контента. OpenCV – очень мощный инструмент, который можно использовать для гораздо более высокоуровневых работ.

На данный момент, я надеюсь, что вам стало гораздо удобнее работать с OpenCV. На самом деле, я бы посоветовал вам почитать официальную документацию и повозиться с кодом, пока я пишу следующую статью этой серии, которую посвящу более сложному контенту.

Ссылки на следующие статьи будут появляться здесь же, так что следите.

Hi, I don’t know if this is a package issue or is a matter of Opencv, I was wanted to do a Arch actualization

but I got a out of disc space error, so I did a

to delete cache files, then I did the actualization, now I can’t import cv2 , I got the traceback:

Traceback (most recent call last):

I got to /usr/lib/python3.7/site-packages/cv2/__init__.py do a copy and then try to solve by myself but I can’t find how to solve, so i restored the copy :

I’m using opencv-3.4.4-1 with Python 3.7.1 , I think that maybe there and opencv problem (not of pacman or or mine) because of this posts

Note :
I already did a

 
sudo pacman -R opencv
sudo pacman -Sc 
sudo pacman -S opencv

but the problem still remains.
