로컬에 python face-recognition 설치

우선 conda는 설치가 되어있어야 함
설치한 적이 없다면.. 이전 블로그나 다른 사이트 참조

1. 패키지 설치는 환경이 꼬일 수 있으니 가상환경내에서 수행

# 가상환경 활성화
conda activate flask-env
(flask-env)

2. conda로 관련 라이브러리(face_recognition_models) 설치

(flask-env) > conda install -y numpy pillow opencv scipy cmake conda-forge dlib akode face_recognition_models
conda install -y numpy pillow opencv scipy cmake conda-forge dlib akode face_recognition_models
...

뭐가 좀 나옴..

Solving environment: failed with initial frozen solve. Retrying with flexible solve.

정상적으로 설치 안된것으로 보여짐 ( PackagesNotFoundError ) 아마도 이유는..

• 정상적인 repository를 못찾았거나..
• 의존성 관련된 패키지를 설치하지 못해서..

3. 의존성을 무시하고 pip로 설치하도록 옵션 변경

# 참조한 블로그에서도 설치실패시 아래와 같이 시도하라고 추천
(flask-env) > pip install --no-dependencies face_recognition
Collecting face_recognition
  Downloading face_recognition-1.3.0-py2.py3-none-any.whl (15 kB)
Installing collected packages: face-recognition
Successfully installed face-recognition-1.3.0

• 깔끔하게 설치됨

4. 설치 확인

(flask-env) > python

import PIL
import face_recognition

Please install `face_recognition_models` with this command before using `face_recognition`:

pip install git+https://github.com/ageitgey/face_recognition_models

정상적으로 설치하려면 저렇게 다시 설치하라고 안내해줌.. ;;

##### 5. git 주소를 추가해서 다시 설치

(flask-env) > pip install git+https://github.com/ageitgey/face_recognition_models

#### 6. 설치 다시 확인

(flask-env) > python

import PIL
import face_recognition

오! 드디어 face_recognition을 로컬 PC에서 사용할 수 있다.
