mindspeed-rl使用注意事项

news 来源：原创 2025/4/22 5:35:17

1、安装

参考1：docs/install_guide.md · R1-CLM/MindSpeed-RL - Gitee.com

参考2：VLLM x Ascend框架_vllm-ascend-CSDN博客

2、SFT微调

整体参考docs/supervised_finetune.md

自定义数据格式同：AUTO-DL 910B + mindspeed-llm 4层DeepSeek V3微调-CSDN博客

第4节，领域语料。

（1）在configs/datasets目录下，新增search_instruction_non_pack.yaml文件（参考alpaca_instruction_non_pack.yaml），注意这里pack和nopack的区别，pack一般用于多轮，含有history等字段，非pack模式下，有instruction,input,output字段即可。

（2）执行sh  examples/data/preprocess_data.sh search_instruction_non_pack，这里preprocess_data脚本有点问题，修改如下：

SCRIPT_DIR=$(cd "$(dirname "$0")" && pwd)
export PYTHONPATH=$SCRIPT_DIR/../..:$PYTHONPATH
PROJECT_PATH=$SCRIPT_DIR/../..# 默认值
default_config="alpaca_pairwise"
config=$1python "$PROJECT_PATH"/cli/preprocess_data.py $config

（3）转换文件格式hf为mcore格式

修改模型目录，设置pp为1，执行：sh examples/ckpt/ckpt_convert_qwen25_hf2mcore.sh

export CUDA_DEVICE_MAX_CONNECTIONS=1# 修改 ascend-toolkit 路径
source /usr/local/Ascend/ascend-toolkit/set_env.sh# 设置需要的权重转换参数
python cli/convert_ckpt.py \--use-mcore-models \--model-type GPT \--load-model-type hf \--save-model-type mg \--target-tensor-parallel-size 1 \--target-pipeline-parallel-size 1 \--add-qkv-bias \--load-dir /root/autodl-tmp/qwen2.5-0.5b \--save-dir /root/autodl-tmp/qwen2.5-0.5b-mcore \--tokenizer-model /root/autodl-tmp/qwen2.5-0.5b/tokenizer.json \--model-type-hf llama2 \--params-dtype bf16

（4）拷贝一份sft_qwen25_0.5b.sh，修改如下：

注意：这里去掉了SOCKET_IFNAME相关设置，改为HCCL_CONNECT_TIMEOUT

#!/bin/bash
export CUDA_DEVICE_MAX_CONNECTIONS=1
export PYTORCH_NPU_ALLOC_CONF=expandable_segments:True
export HCCL_CONNECT_TIMEOUT=3600
export HYDRA_FULL_ERROR=1GPUS_PER_NODE=1
MASTER_ADDR=localhost
MASTER_PORT=6005
NNODES=1
NODE_RANK=0
WORLD_SIZE=$(($GPUS_PER_NODE*$NNODES))DISTRIBUTED_ARGS="--nproc_per_node $GPUS_PER_NODE \--nnodes $NNODES \--node_rank $NODE_RANK \--master_addr $MASTER_ADDR \--master_port $MASTER_PORT
"torchrun $DISTRIBUTED_ARGS cli/train_sft.py \--config-name sft_qwen25_0.5b \| tee logs/sft_qwen25_0.5b_rank${NODE_RANK}.log

拷贝一份sft_qwen25_0.5b.yaml修改如下：

执行： sh examples/sft/sft_qwen25_0.5b.sh

报错：[rank0]: RuntimeError: Error(s) in loading state_dict for GPTModel:
[rank0]:        Missing key(s) in state_dict: "output_layer.weight". 

这个缺陷2月份已经有人提交，但未解决。MindSpeed-r1加载权重报错output_layer.weight key缺失 · Issue #IBNT8L · Ascend/MindSpeed-LLM - Gitee.com

3、GRPO

使用mindspeed-llm中微调好的单层R1作为推理模型。遇到如下报错：

（1）ttributeError: 'AscendQuantConfig' object has no attribute 'packed_modules_mapping'

参考：https://github.com/vllm-project/vllm-ascend/issues/420

建议升级到vllm-ascend RC2，注意原安装说明是有问题的，需要手工下载rc2文件，然后解压安装。

（2）KeyError: 'model.layers.0.self_attn.q_a_proj.weight'

  File "/root/autodl-tmp/vllm-ascend-0.7.3rc2/vllm_ascend/quantization/quant_config.py", line 93, in get_quant_method
    if self.is_layer_skipped_ascend(prefix,
  File "/root/autodl-tmp/vllm-ascend-0.7.3rc2/vllm_ascend/quantization/quant_config.py", line 135, in is_layer_skipped_ascend
    is_skipped = self.quant_description[prefix + '.weight'] == "FLOAT" 

在config.json配置中，有如下配置：

 而在 /root/miniconda3/lib/python3.10/site-packages/vllm/entrypoints/llm.py中有提示：

因此去掉config.json中的相关配置即可。

（3）权重加载找不到目录：

if args.load_format == "megatron":tp_rank = ps._TP.rank_in_groupweights_path = os.path.join(args.load, f"iter_0000100/mp_rank_{tp_rank:02}/model_optim_rng.pt")这里格式如果设置为megatron，检查点文件需要严格匹配。

（4） File "/root/autodl-tmp/mindspeed-rl/mindspeed_rl/models/rollout/vllm_adapter/megatron_weight_loaders.py", line 101, in _get_model_weight_loader
[rank0]:     raise ValueError(f"Model architectures {arch} are not supported for now. "

部分改动如下：

  • config.json文件：

"auto_map": {
"AutoConfig": "configuration_deepseek.DeepseekV3Config"
去掉模型本地实现
},
"hidden_size": 1024,
"intermediate_size": 1024,
去掉quantization_config配置

  • 修改mindspeed_rl\models\rollout\vllm_adapter\megatron_weight_loaders.py文件：

在这个配置中增加：
MODEL_MEGATRON_WEIGHT_LOADER_REGISTRY = {
"CustomDeepseekV3ForCausalLM": deepseek_megatron_weight_loader,
}
原因：vllm-ascend-0.7.3rc2分支中，这个提交https://github.com/vllm-project/vllm-ascend/pull/391/files，使用CustomDeepseekV3ForCausalLM覆盖了原实现。
ModelRegistry.register_model(
"DeepseekV3ForCausalLM",
"vllm_ascend.models.deepseek_v2:CustomDeepseekV3ForCausalLM")

4、FAQ

 停止ray相关进程：ray stop

5、VLLM测试

（1）infer_vllm.py修改如下：


def chat_task(inference_engine, query):conversation = [{"role": "user","content": query,},]import timetokenizer = AutoTokenizer.from_pretrained("/root/autodl-tmp/llama3.2-1b")start_time = time.time()outputs = inference_engine.chat(conversation)res = process_outputs(outputs)out = tokenizer(query + res)logger.info(f'out len: {len(out["input_ids"])}')logger.info('Query: {}'.format(query))logger.info('Responses:\n{}'.format(res))logger.info('costs:{} s'.format(time.time() - start_time))import timestart_time = time.time()outputs = inference_engine.chat([conversation,conversation,conversation,conversation])res = process_outputs(outputs)out = tokenizer(query + res)logger.info(f'out len: {len(out["input_ids"])}')logger.info('Query: {}'.format(query))logger.info('Responses:\n{}'.format(res))logger.info('costs:{} s'.format(time.time() - start_time))start_time = time.time()outputs = inference_engine.chat(conversation)res = process_outputs(outputs)out = tokenizer(query + res)logger.info(f'out len: {len(out["input_ids"])}')logger.info('Query: {}'.format(query))logger.info('Responses:\n{}'.format(res))logger.info('costs:{} s'.format(time.time() - start_time))def generate_task(inference_engine, query):outputs = inference_engine.llm.generate(prompts=[query],sampling_params=inference_engine.sampling_params,)res = process_outputs(outputs)logger.info('Query: {}'.format(query))logger.info('Responses:\n{}'.format(res))

（2）新增infer_vllm_llama32_1b.sh

#!/bin/bash#export GLOO_SOCKET_IFNAME="Your SOCKET IFNAME"
#export TP_SOCKET_IFNAME="Your SOCKET IFNAME"
