Unity ML-Agents를 window의 anaconda3에서 설치하려는 도중 pip install -e . 를 하자 위와 같은 오류가 발생했다.

 

Unity ML-Agents window pip install 에러 원인

---

1. default branch 가 develop 이기 때문이다.

default branch is develop

 

 

2. 요구하는 파이썬 버전이 다르기 때문이다.

 

Unity ML-Agents window pip install 해결 방법

---

1. 그냥 git clone하면 기본 branch인 develop으로 설정되기 때문에 다음과 같이 branch를 지정해 주자.

 

git clone -b latest_release https://github.com/Unity-Technologies/ml-agents.git

 

2. 에러에 적힌 내용대로 파이썬 버전도 맞추자. github의 installation.md를 참고하면 3.8.13 이상이라고 적혀있다.

conda create -n py39 python=3.9
activate py39

 

 

Unity ML-Agents window pip install 결과 화면

---

cuda나 pytorch가 안깔려있다면 깔고, protobuf 버전도 낮추면 다음과 같은 화면이 뜬다.

설치 성공
