2. 로컬에서 DL모델을 실행하기 위한 소스코드를 Nuclio 플랫폼에 적용

2-1 모델을 메모리에 로딩 (init_context(context)함수를 사용하여)

https://nuclio.io/docs/latest/concepts/best-practices-and-common-pitfalls/#use-init_context-instead-of-global-variable-declarations-or-function-calls

2-2 아래 프로세스를 위해 handler에 entry point를 정의하고, main.py에 넣는다.

  • accept incoming HTTP requests
  • run inference
  • reply with detection results
