Не удается установить dlib на Windows 10 и Python 3.7

Question

Я пытаюсь установить OpenCV, dlib на Windows 10 на anaconda python 3.7. Я установил Visual Studio 2015 в качестве предварительного условия вместе с CMake. Когда я пытаюсь установить dlib на мой компьютер, он выдает ошибку ниже. Я также не могу установить OpenCV. Я попытался установить dlib с помощью файла .whl. Но все равно не повезло.

Answer 1

Я пробовал так много вещей, чтобы работать с последней версией Anaconda, которая является Python 3.7. Однако я не смог этого сделать. Потому что ни один из файлов .whl не был совместим с 3.7, но с 3.6. Итак, по ссылке понизили версию Python до 3.6. Таким образом, spyder и python будут понижены до версии 3.6. После этого я установил opencv с помощью приведенных ниже команд.

pip install opencv-python
pip install opencv-contrib-python

Я установил dlib с помощью следующей команды.

pip install dlib-19.8.1-cp36-cp36m-win_amd64.whl

Это успешно установило последнюю версию dlib.

Чтобы проверить, все ли установлено правильно, я использовал следующие команды и вывод, полученный в приглашении Anaconda.

(py36) C:\Users\dbi227>python
Python 3.6.9 |Anaconda, Inc.| (default, Jul 30 2019, 14:00:49) [MSC v.1915 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'4.1.1'
>>> import dlib
>>> dlib.__version__
'19.8.1'

Важно проверить, не снизился ли ваш iPython до 3,6 илине. Для этого я получил опцию spyder (py36), кроме spyder (anaconda3), в моей стартовой опции. Убедитесь, что вы нажимаете на spyder (py36). Потому что именно там установлены библиотеки. Чтобы проверить это, вы можете просто набрать

import cv2
import dlib

Если эти команды не показывают ошибок, то библиотеки установлены правильно.
