Review Comment:
this is a AI-recommended approach, and the source is
https://pythonspeed.com/articles/activate-virtualenv-dockerfile/
```
FROM python:3.12-slim
RUN python3 -m venv /opt/venv
# This is wrong!
RUN . /opt/venv/bin/activate
# Install dependencies:
COPY requirements.txt .
RUN pip install -r requirements.txt
# Run the application:
COPY myapp.py .
CMD ["python", "myapp.py"]
```
it said the the normal way to activate venv only take effect in its `RUN`
command, I did try it though
