On arm64 experiment containers fail due to missing pypi ray package

[rdnfn]

Problem

In arm64 architecture-based containers (e.g. on M1 macs) the experiment containers fail due to the ray package not being available (they only provide x86 wheels via pypi).

Solution

There are a few different approaches to tackle this problem:

• Build custom ray package in container if on arm64 (see guide to building arm64 ray)
• Run experiment containers in compatiblity mode via x86 (this is slow and can only be used for testing)

Edit:

The focus will now be on getting a development version running without necessarily going for full performance.

Potential solution:

• Move build pipeline to docker buildx to add --platform linux/amd64 and use build contexts from local package data from submodule.
