먼가 설치하려는데 먼가 안되서, venv 사용 해보는 중
| $ pip3 install keras mobilenet-v3 numpy tensorflow error: externally-managed-environment × This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.14/README.venv for more information. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification. |
인자없이 모듈만 불러오면 당연히(?) 실행 안되고 에러가 난다.

activate를 불러오고 deactivate 명령으로 종료한다.
아무생각없이 자꾸 exit 해서 터미널 닫아버리네 -_-

대충 rootfs가 생겨난다.

어쩐지 찾아도 안나온다 했더니 함수로 등록해버리는 듯

새로 생성한 환경은 13M 정도
| $ du -h -d 1 test 13M test/lib 40K test/bin 4.0K test/include 13M test |
3개 설치했더니
| pip3 install keras mobilenet-v3 numpy |
161M 로 확 늘었다. 내려가서 보니 pip가 설치되서 그렇네.
| $ du -h -d 1 venv/ 161M venv/lib 128K venv/bin 4.0K venv/include 161M venv/ |
