Docker image isn't working for poweron -ppc64le
I am par of IBM team and working on power support for this package and faced the below issue during build

It looks the problem is with starting docker can you help with the below method (suggestions) for power on support to enable
1- The images for ppc64le can be built and pushed manually by doing native builds on ppc64le VMs available via OSU, OSL https://osuosl.org/services/powerdev/request_hosting/ (do let me know if you choose to go via that path and I can share more specific details). Once the Power images are published, multiarch manifests can be used https://www.docker.com/blog/multi-arch-build-and-images-the-simple-way/ to ensure support across different architectures, this would need to be created and published as well. 2- The process can be automated via travis-ci using multi-stage travis builds as shown here https://www.youtube.com/watch?v=_PbpRETbpow 3- not ideal from a performance perspective, but we can do cross-builds using docker buildx.
Pls tag @seth-priya and me for further clarification.
pls rfere job https://travis-ci.com/github/asellappen/pyclipper/jobs/451426919 for error details
We never tested this architecture (I personally wasn't aware of its existence). From the error it looks like the docker image with the wrong architecture (x86_64) is being pulled. I think you should redirect your feature request to https://github.com/matthew-brett/multibuild, which is the suite of shell tools that we use to automate building wheel packages for linux.
looks like multibuild does support "ppc64le" https://github.com/matthew-brett/multibuild/search?q=ppc64le
It might be a simple config flag to enable this on our side, but I don't have time to look into it right now.
