Miles runs on AMD Instinct GPUs (MI300, MI325, MI350, MI355X) with ROCm. The launch scripts are the same as on NVIDIA — only the container and a few env vars differ.

​
Container images

docker pull rlsys/miles:MI350-355-latest

# MI300 / MI325
docker pull rlsys/miles:MI300-latest
Or build from the repo: 
cd docker
docker build -f Dockerfile.rocm_MI350-5 -t rlsys/miles:latest .
The base ROCm image bundles the patches needed for virtual memory management on MI300X — thanks to Yang Wang for that work.

​
Launch the container

docker run --rm -it \
  --device /dev/dri \
  --device /dev/kfd \
  -p 8265:8265 \
  --group-add video \
  --cap-add SYS_PTRACE \
  --security-opt seccomp=unconfined \
  --privileged \
  -v $HOME/.ssh:/root/.ssh \
  -v $HOME:$HOME \
  --shm-size 128G \
  --name miles_dev \
  --ulimit memlock=-1 --ulimit stack=67108864 \
  -w $PWD \
  rlsys/miles:latest \
  /bin/bash
Inside, install Miles editable: 
git clone https://github.com/radixark/miles.git
cd miles && pip install -e . --no-deps

Download model + data

hf download Qwen/Qwen3-4B --local-dir /root/Qwen3-4B

​
Convert weights (CPU + Gloo)

We force CPU-only conversion on AMD to bypass some ROCm-specific issues. A GPU-based ROCm converter is in development. 
cd /root/miles
source scripts/models/qwen3-4B.sh
MEGATRON_LM_PATH=$(pip list | grep megatron-core | awk '{print $NF}')

PYTHONPATH=${MEGATRON_LM_PATH} python tools/convert_hf_to_torch_dist.py \
   ${MODEL_ARGS[@]} \
   --hf-checkpoint /root/Qwen3-4B \
   --save           /root/Qwen3-4B_torch_dist
If you see miles cannot be found, re-run pip install -e . --no-deps in the repo.

​
Launch

The standard scripts/run-qwen3-4B.sh works as-is. The image already sets the ROCm-specific env vars you’d otherwise need: 
HSA_OVERRIDE_GFX_VERSION=11.0.0   # or 9.4.0 for MI300
NCCL_NET=Socket                   # for non-RDMA setups
NCCL_IB_HCA=...                   # if your fabric supports it
PYTORCH_NO_HIP_MEMORY_CACHING=0
