| # AMD GPU 支持 |
|
|
| ## 1. 环境配置 |
| ### 1.1 基础环境 |
| 拉取适配了 AMD ROCm 生态的 ms-swift 镜像，并参照以下命令启动容器。 |
|
|
| 如果用户需要运行更新版本的 ms-swift，可以使用 pip 升级或基于源码安装更新（建议安装时添加 `--no-deps` 选项以避免自动升级其他依赖可能引起的问题）。 |
|
|
| ```bash |
| IMAGE_NAME=amdagi/modelscope:ubuntu22.04-rocm7.2.0-py312-torch2.10.0-vllm0.18.1-modelscope1.35.1-swift4.1.0 |
| docker pull ${IMAGE_NAME} |
| |
| CONTAINER_NAME=swift_test |
| docker run -it --network=host --ipc=host --privileged --group-add video \ |
| --device=/dev/dri --device=/dev/kfd \ |
| --shm-size 512G --ulimit memlock=-1 \ |
| --security-opt seccomp=unconfined --cap-add SYS_PTRACE \ |
| --name ${CONTAINER_NAME} \ |
| ${IMAGE_NAME} \ |
| /bin/bash |
| ``` |
|
|
| ### 1.2 环境检查 |
|
|
| - 确认 container 环境中 pytorch 正确识别 AMD GPU。 |
|
|
| ```bash |
| python -c "import torch;print(torch.cuda.is_available())" # output: True |
| ``` |
|
|
| - 检查 GPU 的拓扑连接及 NUMA：`rocm-smi --showtopo` |
|
|
| ``` |

| ## 2. 运行示例 |
|
|
| ### 2.1 使用 Megatron-Swift 全量微调 Qwen3.5 模型 |
| AMD GPU 显存相对较大，因此可以通过同时对以下参数进行联合调优，以提升训练吞吐性能。 |
| - 并行度调优（TP/PP/EP等）：GPU 单卡显存较大使得用户可以尽可能减小并行度切分带来的通信开销（优先级 PP/EP > TP） |
| - 显存允许的情况下关闭 optimizer cpu offload：设置 `--optimizer_cpu_offload false` |
| - 显存允许的情况下调整 activation/gradient checkpointing：设置 `--recompute_granularity none`，或者 `--recompute_granularity selective` 配合 `--recompute_modules` 进行细粒度的控制 |
| - 对于 MoE 模型，建议设置 `export NVTE_USE_CUTLASS_GROUPED_GEMM=1` 以使用优化的 grouped gemm kernel |
| - 对于带有 GatedDeltaNet 结构的模型，建议设置 `USE_MCORE_GDN=1` 使用 mcore 的实现版本 |
| - 为避免在某些 AMD GPU 上可能出现的问题，保证性能更稳定，建议设置 `export HSA_NO_SCRATCH_RECLAIM=1` |

|
| ## 已知问题 |
| - 强化学习训练： |
| - 在强化学习训练中，如果使用 vLLM 作为推理引擎，需要 vLLM>=0.11.0。建议使用 ROCm7.0 或者我们提供的镜像以避免出现 sleep mode memory leak 问题。 |
| - MoE 模型训练： |
| - MoE模型建议增加环境变量 NVTE_USE_CUTLASS_GROUPED_GEMM=1 以避免偶发的GPU卡死问题。 |
