Unable to install inside the Docker container

Hi.

It's a really cool project and it works nice but not in the docker container. For some reason, I'm getting error during installation:

Part of my dockerfile:

FROM python:3.8.5-alpine
RUN apk add build-base linux-headers ethtool zlib-dev jpeg-dev freetype-dev
RUN pip3 install wheel luma.core luma.oled psutil PySensors

I'm not closely familiar with docker and python, so maybe the issue isn't related to the library itself.

I think there are two issues:

• You are installing another Python module with the same name: https://pypi.org/project/PySensors. (I know, that’s horribly confusing, maybe I will change this project’s name eventually.) I’ve never published my project as a package.
• The lm_sensors library doesn’t seem to be there. This should be easy to fix, see https://wiki.alpinelinux.org/wiki/Setting_up_lm_sensors.

Here is a docker file that works for this project:

FROM python:3.8.5-alpine
RUN apk add git build-base bison flex

RUN git clone https://github.com/lm-sensors/lm-sensors.git /lmsensors && \
    cd /lmsensors && make install && \
    git clone https://github.com/bastienleonard/pysensors.git /pysensors && \
    cd /pysensors && python setup.py build_ext --inplace

WORKDIR /pysensors
CMD ["python", "-c", "import sensors; print(sensors.get_detected_chips())"]

I’m installing lm_sensors from GitHub because I couldn’t figure out how to get the headers otherwise.

Thank you, I'll try to install it in this way.
