ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts. isaacsim-core 4.2.0.2 requires numpy<2.0.0, but you have numpy 2.2.2 which is incompatible. omni-isaac-lab 0.30.6 requires numpy<2, but you have numpy 2.2.2 which is incompatible.

위 오류는 설치된 **numpy 버전(2.2.2)**이 Isaac Sim과 omni-isaac-lab이 요구하는 버전(2.0.0 미만)과 호환되지 않음을 나타냅니다.

이 문제는 설치가 진행되더라도 나중에 실행 중 예기치 않은 오류를 발생시킬 가능성이 있으므로, 해결하는 것이 좋습니다.

해결 방법

numpy 버전을 맞춰 설치하여 충돌을 해결하세요:

1. numpy를 제거 후 호환 버전 설치

   bash
   복사편집
   pip uninstall -y numpy
   pip install "numpy<2.0.0"
   
   

2. 설치된 numpy 버전 확인

   bash
   복사편집
   python -c "import numpy; print(numpy.__version__)"
   
   

   • 출력이 2.0.0 미만 버전이어야 합니다.

3. 다시 설치 스크립트 실행

   bash
   복사편집
   ./isaaclab.sh --install
