| | | param_dict={"decoding_model": decoding_model}) |
| | | |

| | | print(rec_result) |
| | | ``` |
| | | fast 和 normal 的解码模式是假流式解码,可用于评估识别准确性。 |

| | | ``` |
| | | |
| | | ### API接口说明 |
| | | #### pipeline定义 |
| | | - `task`: `Tasks.auto_speech_recognition` |
| | | - `model`: [模型仓库](https://alibaba-damo-academy.github.io/FunASR/en/model_zoo/modelscope_models.html#pretrained-models-on-modelscope) 中的模型名称,或本地磁盘中的模型路径 |
| | | - `ngpu`: `1`(默认),使用 GPU 进行推理。如果 ngpu=0,则使用 CPU 进行推理 |
| | | - `ncpu`: `1` (默认),设置用于 CPU 内部操作并行性的线程数 |
| | | - `output_dir`: `None` (默认),如果设置,输出结果的输出路径 |
| | | - `batch_size`: `1` (默认),解码时的批处理大小 |

| | | - `audio_in`: 要解码的输入,可以是: |
| | | - wav文件路径, 例如: asr_example.wav, |
| | | - pcm文件路径, 例如: asr_example.pcm, |
| | | - 音频字节数流,例如:麦克风的字节数数据 |
| | | - 音频采样点,例如:`audio, rate = soundfile.read("asr_example_zh.wav")`, 数据类型为 numpy.ndarray 或者 torch.Tensor |
| | | - wav.scp,kaldi 样式的 wav 列表 (`wav_id \t wav_path`), 例如: |
| | | ```text |
| | | asr_example1 ./audios/asr_example1.wav |
| | | asr_example2 ./audios/asr_example2.wav |
| | | ``` |
| | | 在这种输入 `wav.scp` 的情况下,必须设置 `output_dir` 以保存输出结果 |
| | | - `audio_fs`: 音频采样率,仅在 audio_in 为 pcm 音频时设置 |
| | | - `output_dir`: None (默认),如果设置,输出结果的输出路径 |
| | | |
| | | ### 使用多线程 CPU 或多个 GPU 进行推理 |
| | | FunASR 还提供了 [egs_modelscope/asr/TEMPLATE/infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) 脚本,以使用多线程 CPU 或多个 GPU 进行解码。 |
| | | |
| | | #### `infer.sh` 设置 |
| | | - `model`: [modelscope模型仓库](https://alibaba-damo-academy.github.io/FunASR/en/model_zoo/modelscope_models.html#pretrained-models-on-modelscope)中的模型名称,或本地磁盘中的模型路径 |
| | | - `data_dir`: 数据集目录需要包括 `wav.scp` 文件。如果 `${data_dir}/text` 也存在,则将计算 CER |
| | | - `output_dir`: 识别结果的输出目录 |
| | | - `batch_size`: `64`(默认),在 GPU 上进行推理的批处理大小 |
| | | - `gpu_inference`: `true` (默认),是否执行 GPU 解码,如果进行 CPU 推理,则设置为 `false` |
| | | - `gpuid_list`: `0,1` (默认),用于推理的 GPU ID |
| | | - `njob`: 仅用于 CPU 推理(`gpu_inference=false`),`64`(默认),CPU 解码的作业数 |
| | | - `checkpoint_dir`: 仅用于推理微调模型,微调模型的路径目录 |
| | | - `checkpoint_name`: 仅用于推理微调模型,`valid.cer_ctc.ave.pb`(默认),用于推理的检查点 |
| | | - `decoding_mode`: `normal`(默认),UniASR 模型的解码模式(`fast`、`normal`、`offline`) |
| | | - `hotword_txt`: `None` (默认),上下文语料库模型的热词文件(热词文件名以 .txt 结尾) |
| | | |
| | | #### 使用多个 GPU 进行解码: |
| | | ```shell |
| | | bash infer.sh \ |
| | | --model "damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch" \ |
| | | --data_dir "./data/test" \ |
| | | --output_dir "./results" \ |
| | | --batch_size 64 \ |
| | | --gpu_inference true \ |
| | | --gpuid_list "0,1" |
| | | ``` |
| | | #### 使用多线程 CPU 进行解码: |
| | | ```shell |
| | | bash infer.sh \ |
| | | --model "damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch" \ |
| | | --data_dir "./data/test" \ |
| | | --output_dir "./results" \ |
| | | --gpu_inference false \ |
| | | --njob 64 |
| | | ``` |
| | | |
| | | #### 推理结果 |
| | | 解码结果可以在 `$output_dir/1best_recog/text.cer` 中找到,其中包括每个样本的识别结果和整个测试集的 CER 指标。 |
| | | 如果您对 SpeechIO 测试集进行解码,则可以使用 `stage=3` 的 textnorm,`DETAILS.txt` 和 `RESULTS.txt` 记录了文本标准化后的结果和 CER。 |

| | | ## 使用pipeline进行微调 |
| | | |
| | | ### 快速上手 |
| | | [finetune.py](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/finetune.py) |
| | | ```python |
| | | import os |
| | | |
| | | from modelscope.metainfo import Trainers |
| | | from modelscope.trainers import build_trainer |
| | | |
| | | from funasr.datasets.ms_dataset import MsDataset |
| | | from funasr.utils.modelscope_param import modelscope_args |
| | | |
| | | |
| | | def modelscope_finetune(params): |
| | | if not os.path.exists(params.output_dir): |
| | | os.makedirs(params.output_dir, exist_ok=True) |
| | | # dataset split ["train", "validation"] |
| | | ds_dict = MsDataset.load(params.data_path) |
| | | kwargs = dict( |
| | | model=params.model, |
| | | data_dir=ds_dict, |
| | | dataset_type=params.dataset_type, |
| | | work_dir=params.output_dir, |
| | | batch_bins=params.batch_bins, |
| | | max_epoch=params.max_epoch, |
| | | lr=params.lr, |
| | | mate_params=params.param_dict) |
| | | trainer = build_trainer(Trainers.speech_asr_trainer, default_args=kwargs) |
| | | trainer.train() |
| | | |
| | | |
| | | if __name__ == '__main__': |
| | | params = modelscope_args(model="damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch") |
| | | params.output_dir = "./checkpoint" # m模型保存路径 |
| | | params.data_path = "speech_asr_aishell1_trainsets" # 数据路径 |
| | | params.dataset_type = "small" # 小数据量设置small,若数据量大于1000小时,请使用large |
| | | params.batch_bins = 2000 # batch size,如果dataset_type="small",batch_bins单位为fbank特征帧数,如果dataset_type="large",batch_bins单位为毫秒, |
| | | params.max_epoch = 20 # 最大训练轮数 |
| | | params.lr = 0.00005 # 设置学习率 |
| | | init_param = [] # 初始模型路径,默认加载modelscope模型初始化,例如: ["checkpoint/20epoch.pb"] |
| | | freeze_param = [] # 模型参数freeze, 例如: ["encoder"] |
| | | ignore_init_mismatch = True # 是否忽略模型参数初始化不匹配 |
| | | use_lora = False # 是否使用lora进行模型微调 |
| | | params.param_dict = {"init_param":init_param, "freeze_param": freeze_param, "ignore_init_mismatch": ignore_init_mismatch} |
| | | if use_lora: |
| | | enable_lora = True |
| | | lora_bias = "all" |
| | | lora_params = {"lora_list":['q','v'], "lora_rank":8, "lora_alpha":16, "lora_dropout":0.1} |
| | | lora_config = {"enable_lora": enable_lora, "lora_bias": lora_bias, "lora_params": lora_params} |
| | | params.param_dict.update(lora_config) |
| | | |
| | | modelscope_finetune(params) |
| | | ``` |
| | | |
| | | ```shell |
| | | python finetune.py &> log.txt & |
| | | ``` |
| | | |
| | | ### 使用私有数据进行微调 |
| | | |
| | | - 修改 [finetune.py](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/finetune.py) 中微调训练相关参数 |
| | | - `output_dir`: 微调模型保存路径 |
| | | - `data_dir`: 数据集目录需要包括以下文件:`train/wav.scp`, `train/text`; `validation/wav.scp`, `validation/text` |
| | | - `dataset_type`: 对于大于 1000 小时的数据集,设置为 `large`,否则设置为 `small` |
| | | - `batch_bins`: 批处理大小。对于 `dataset_type` 为 `small`,`batch_bins` 表示特征帧数。对于 `dataset_type` 为 `large`,`batch_bins` 表示以毫秒为单位的持续时间 |
| | | - `max_epoch`: 最大训练 epoch 数量 |
| | | - `lr`: 学习率 |
| | | - `init_param`: `[]`(默认值),初始化模型路径,按默认设置加载 modelscope 模型初始化。例如:["checkpoint/20epoch.pb"] |
| | | - `freeze_param`: `[]`(默认值),冻结模型参数。例如:["encoder"] |
| | | - `ignore_init_mismatch`: `True`(默认值),在加载预训练模型时忽略大小不匹配 |
| | | - `use_lora`: `False`(默认值),微调模型使用 LORA,请参阅 [LORA论文](https://arxiv.org/pdf/2106.09685.pdf) |
| | | |
| | | - 训练数据格式 |
| | | ```sh |
| | | cat ./example_data/text |
| | | BAC009S0002W0122 而 对 楼 市 成 交 抑 制 作 用 最 大 的 限 购 |
| | | BAC009S0002W0123 也 成 为 地 方 政 府 的 眼 中 钉 |
| | | english_example_1 hello world |
| | | english_example_2 go swim 去 游 泳 |
| | | |
| | | cat ./example_data/wav.scp |
| | | BAC009S0002W0122 /mnt/data/wav/train/S0002/BAC009S0002W0122.wav |
| | | BAC009S0002W0123 /mnt/data/wav/train/S0002/BAC009S0002W0123.wav |
| | | english_example_1 /mnt/data/wav/train/S0002/english_example_1.wav |
| | | english_example_2 /mnt/data/wav/train/S0002/english_example_2.wav |
| | | ``` |
| | | |
| | | - 然后,您可以使用以下命令运行pipeline进行微调: |
| | | ```shell |
| | | python finetune.py |
| | | ``` |
| | | 如果您想使用多个 GPU 进行微调,可以使用以下命令: |
| | | ```shell |
| | | CUDA_VISIBLE_DEVICES=1,2 python -m torch.distributed.launch --nproc_per_node 2 finetune.py > log.txt 2>&1 |
| | | ``` |
| | | ## 使用微调模型进行推理 |
| | | |
| | | [egs_modelscope/asr/TEMPLATE/infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) 参数设置与上面`infer.sh`相同 |
| | | |
| | | - 使用多个 GPU 进行解码: |
| | | ```shell |
| | | bash infer.sh \ |
| | | --model "damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch" \ |
| | | --data_dir "./data/test" \ |
| | | --output_dir "./results" \ |
| | | --batch_size 64 \ |
| | | --gpu_inference true \ |
| | | --gpuid_list "0,1" \ |
| | | --checkpoint_dir "./checkpoint" \ |
| | | --checkpoint_name "valid.cer_ctc.ave.pb" |
| | | ``` |
| | | - 使用多线程 CPU 进行解码: |
| | | ```shell |
| | | bash infer.sh \ |
| | | --model "damo/speech_paraformer-large_asr_nat-zh-cn-16k-common-vocab8404-pytorch" \ |
| | | --data_dir "./data/test" \ |
| | | --output_dir "./results" \ |
| | | --gpu_inference false \ |
| | | --njob 64 \ |
| | | --checkpoint_dir "./checkpoint" \ |
| | | --checkpoint_name "valid.cer_ctc.ave.pb" |
| | | ``` |
