slimmed version of python3.10 version seems to loose package(s)

Expected Behavior

docker run of my image runs perfectly my python code using various packages (important here: juniper pyez and cryptography)

Actual Behavior

docker run of the slim version crashes
output here :

Error processing line 1 of /usr/local/lib/python3.10/site-packages/junos_eznc-2.6.3-py3.7-nspkg.pth:

Dockerfile:

FROM python:3

WORKDIR /usr/src/app
RUN mkdir /usr/src/app/conf
RUN mkdir /usr/src/app/Routers
RUN mkdir /usr/src/app/enrichement

COPY ./enrichment /usr/src/app/enrichment
COPY ./Routers /usr/src/app/Routers
WORKDIR /usr/src/app/Routers
RUN pip install --no-cache-dir -r requirements.txt
RUN python3 setup.py sdist bdist_wheel
RUN pip3 install ./
WORKDIR /usr/src/app/

CMD ["python", "./enrichment/ios_xr_interfaces.py"]

Start with the Dockerfile, requirements.txt, and setup.py, then compare the regular and slim Python images described in the report. Reproduce the ModuleNotFoundError for cryptography.fernet and the junos_eznc warning, and identify whether slimming removed packages needed by the installed application; done means the slim image runs the provided command successfully.
