Pystan 2 Dockerfile Example?

[Jiggly_Square]

Does anyone have an example of a dockerfile that they have used to get Pystan 2.19 working?

All my attempts so far have resulted in me getting the same error when I go to compile a model: distutils.errors.CompileError: command ‘gcc’ failed with exit status 1

Here is my (non-working dockerfile):
FROM python:3.8-slim-bullseye

RUN echo ‘deb Index of /debian testing main’ >> /etc/apt/sources.list
&& apt-get update -y
&& apt-get install -y gcc
&& rm -rf /var/lib/apt/lists/*

RUN pip install numpy
cython
pystan==2.19.1.1

And when I run the command gcc --version in the container I get: gcc (Debian 11.2.0-12) 11.2.0

I appreciate any ideas. Thank you.

Could you try installing build-essential?

You might also need python-dev.

You could also try using a non-slim base image, e.g. python:3.10.0-bullseye

That sufficed for the latest version of pystan a month ago:

Pystan 3, gcc compilers and Docker images

That’s great, thanks! I think (at time of writing) the python:3.9 and python:latest (i.e. python:3.10.0-bullseye) Docker images are now running on Debian Bullseye, which has gcc 10, so it’s no longer necessary to update gcc and it should be sufficient to just pip install pystan directly in the new Python Docker images. FROM python:3.10.0-bullseye # Install PyStan RUN pip install pystan

Can confirm that this does appear to work just fine on the non-slim base image (and with no need to install gcc)

FROM python:3.8-bullseye

RUN pip install numpy cython pystan==2.19.1.1

(I tested it with the 8schools example on the Pystan2 getting started page and it compiled and sampled successfully)
