Ray-ml docker image for armv7 architecture?

I wonder if is possible to make docker images ray-ml:

https://hub.docker.com/r/rayproject/ray-ml for architectures:

linux/arm64,linux/arm/v7, linux/arm/v6

I tried to build from ray-ml image with:

FROM rayproject/ray-ml
CMD ["/bin/bash"]

docker buildx build --platform linux/arm/v7 --push -t peterpirogtf/ray_tf2:armv7 .

Unfortunatelly the error:

standard_init_linux.go:219: exec user process caused: exec format error

suggest (in my opinion) that there is some problem with architecture compatibility.
