Подушка, которую я уже установил.

pip install pillow
Requirement already satisfied: pillow in /usr/lib/python3/dist-packages (5.1.0)

Я хотел бы запустить код для преобразованияизображение в .txt.

РЕДАКТИРОВАТЬ После вашего совета я попробовал это:

У меня есть этот .py файл, который должен преобразовывать изображения в строки.

img2str.py:

from PIL import Image
from pytesseract import image_to_string

image = Image.open('image.png', mode='r')
print(image_to_string(image))


python3 img2str.py
Traceback (most recent call last):
  File "/home/linux/.local/lib/python3.6/site-packages/pytesseract/pytesseract.py", line 223, in run_tesseract
    proc = subprocess.Popen(cmd_args, **subprocess_args())
  File "/usr/lib/python3.6/subprocess.py", line 729, in __init__
    restore_signals, start_new_session)

    raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'tesseract': 'tesseract'

During handling of the above exception, another exception occurred:

    results = tes.image_to_string(Image.open('image.png'))

sudo pip install pytesseract --user
[sudo] heslo pro linux:    
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main

По вашему совету я использовал запятую во второй раз, и она, кажется, установлена.

pip install pytesseract --user
Requirement already satisfied: pytesseract in ./.local/lib/python3.6/site-packages (0.3.0)

Answer 1

Эта ошибка вызвана тем, что у вас нет разрешения на создание временного файла, который требуется для установки pytesseract.

Если вы запустите pip install pytesseract --user, который должен решить вашу проблему.

Если это не решит проблему, запустите sudo pip install pytesseract --user, поскольку он использует самый высокий уровень доступа, который может предоставить системавы.
