Switch compiler

This image includes both FlagTree (default) and Triton. To switch, run compiler triton inside the container. Use compiler flagtree to switch back, or compiler to check the active compiler.

Launch

With the container toolkit (optional):

  metax-docker \
  run \
  --rm \
  -it \
  harbor.baai.ac.cn/flagos-runtime/flagos-runtime-metax-maca3.7.2.1:2.1.2 bash

Without a toolkit — plain docker / podman:

  docker run --rm -it \
  --device /dev/mxcd \
  --device /dev/dri \
  --group-add video \
  harbor.baai.ac.cn/flagos-runtime/flagos-runtime-metax-maca3.7.2.1:2.1.2 bash

Verify

Inside the container, confirm the accelerator is visible:

  mx-smi
