아나콘다 다운로드 및 설치

 

가상환경 들어가서 pip update 필요하다. 

conda update pip

현재 (base) 환경에서 사용중인 파이썬 버전을 확인하려면 다음 명령을 실행합니다.

PIP는 Python Package Index (PyPI) 저장소로부터 패키지를 다운받아 설치 및 관리해주는 패키지 매니저 입니다. pip install [패키지 이름]의 형태로 패키지를 설치하면 됩니다.
Pip를 최신 버전으로 업그레이드 하려면 다음 명령을 실행합니다.
(base) PS D:\_py_project> python --version

(base) PS D:\_py_project> python -m pip install --upgrade pip

아나콘다 패키지 업데이트

(base) C:\Users\사용자계정>conda -–version

(base) C:\Users\사용자계정>conda update --all

Facial Expression or Facial Emotion Detector can be used to know whether a person is sad, happy, angry and so on only through his/her face. This Repository can be used to carry out such a task.

This is the code for this video by Ritesh on YouTube.

Facial Expression or Facial Emotion Detector can be used to know whether a person is sad, happy, angry and so on only through his/her face. This Repository can be used to carry out such a task. It uses your WebCamera and then identifies your expression in Real Time. Yeah in real-time!

PLAN
This is a three step process. In the first, we load the XML file for detecting the presence of faces and then we retrain our network with our image on five diffrent categories. After that, we import the label_image.py program from the last video and set up everything in realtime.
