| | | ## Inference |
| | | |
| | | ### Quick start |

| | | #### API-reference |
| | | ##### define pipeline |
| | | ##### Define pipeline |
| | | - `task`: `Tasks.auto_speech_recognition` |
| | | - `model`: model name in [model zoo](https://alibaba-damo-academy.github.io/FunASR/en/modelscope_models.html#pretrained-models-on-modelscope), or model path in local disk |
| | | - `ngpu`: 1 (Defalut), decoding on GPU. If ngpu=0, decoding on CPU |
| | | - `ncpu`: 1 (Defalut), sets the number of threads used for intraop parallelism on CPU |
| | | - `output_dir`: None (Defalut), the output path of results if set |
| | | - `batch_size`: 1 (Defalut), batch size when decoding |
| | | ##### infer pipeline |
| | | ##### Infer pipeline |
| | | - `audio_in`: the input to decode, which could be: |
| | | - wav_path, `e.g.`: asr_example.wav, |
| | | - pcm_path, `e.g.`: asr_example.pcm, |
| | | - audio bytes stream, `e.g.`: bytes data from a microphone |
| | | - audio sample point,`e.g.`: `audio, rate = soundfile.read("asr_example_zh.wav")`, the dtype is numpy.ndarray or torch.Tensor |
| | | - wav.scp, kaldi style wav list (`wav_id \t wav_path``), `e.g.`: |
| | | ```cat wav.scp |
| | | ```text |
| | | asr_example1 ./audios/asr_example1.wav |
| | | asr_example2 ./audios/asr_example2.wav |
| | | ``` |
| | |
| | | FunASR also offer recipes [infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) to decode with multi-thread CPUs, or multi GPUs. |
| | | |
| | | - Setting parameters in `infer.sh` |
| | | - <strong>model:</strong> # model name on ModelScope |
| | | - <strong>data_dir:</strong> # the dataset dir needs to include `${data_dir}/wav.scp`. If `${data_dir}/text` is also exists, CER will be computed |
| | | - <strong>output_dir:</strong> # result dir |
| | | - <strong>batch_size:</strong> # batchsize of inference |
| | | - <strong>gpu_inference:</strong> # whether to perform gpu decoding, set false for cpu decoding |
| | | - <strong>gpuid_list:</strong> # set gpus, e.g., gpuid_list="0,1" |
| | | - <strong>njob:</strong> # the number of jobs for CPU decoding, if `gpu_inference`=false, use CPU decoding, please set `njob` |
| | | - `model`: model name on ModelScope |
| | | - `data_dir`: the dataset dir needs to include `${data_dir}/wav.scp`. If `${data_dir}/text` is also exists, CER will be computed |
| | | - `output_dir`: result dir |
| | | - `batch_size`: batchsize of inference |
| | | - `gpu_inference`: whether to perform gpu decoding, set false for cpu decoding |
| | | - `gpuid_list`: set gpus, e.g., `gpuid_list`="0,1" |
| | | - `njob`: the number of jobs for CPU decoding, if `gpu_inference`=false, use CPU decoding, please set `njob` |
| | | - `checkpoint_dir`: only used for infer finetuned models, the path dir of finetuned models |
| | | - `checkpoint_name`: only used for infer finetuned models, `valid.cer_ctc.ave.pb` (Default), which checkpoint is used to infer |
| | | |
| | | - Decode with multi GPUs: |
| | | ```shell |
| | |
| | | ### Finetune with your data |
| | | |
| | | - Modify finetune training related parameters in [finetune.py](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/finetune.py) |
| | | - <strong>output_dir:</strong> # result dir |
| | | - <strong>data_dir:</strong> # the dataset dir needs to include files: `train/wav.scp`, `train/text`; `validation/wav.scp`, `validation/text` |
| | | - <strong>dataset_type:</strong> # for dataset larger than 1000 hours, set as `large`, otherwise set as `small` |
| | | - <strong>batch_bins:</strong> # batch size. For dataset_type is `small`, `batch_bins` indicates the feature frames. For dataset_type is `large`, `batch_bins` indicates the duration in ms |
| | | - <strong>max_epoch:</strong> # number of training epoch |
| | | - <strong>lr:</strong> # learning rate |
| | | - `output_dir`: result dir |
| | | - `data_dir`: the dataset dir needs to include files: `train/wav.scp`, `train/text`; `validation/wav.scp`, `validation/text` |
| | | - `dataset_type`: for dataset larger than 1000 hours, set as `large`, otherwise set as `small` |
| | | - `batch_bins`: batch size. For dataset_type is `small`, `batch_bins` indicates the feature frames. For dataset_type is `large`, `batch_bins` indicates the duration in ms |
| | | - `max_epoch`: number of training epoch |
| | | - `lr`: learning rate |
| | | |
| | | - Then you can run the pipeline to finetune with: |
| | | ```shell |
| | |
| | | CUDA_VISIBLE_DEVICES=1,2 python -m torch.distributed.launch --nproc_per_node 2 finetune.py > log.txt 2>&1 |
| | | ``` |
| | | ## Inference with your finetuned model |
| | | - Modify inference related parameters in [infer_after_finetune.py](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer_after_finetune.py) |
| | | - <strong>modelscope_model_name: </strong> # model name on ModelScope |
| | | - <strong>output_dir:</strong> # result dir |
| | | - <strong>data_dir:</strong> # the dataset dir needs to include `test/wav.scp`. If `test/text` is also exists, CER will be computed |
| | | - <strong>decoding_model_name:</strong> # set the checkpoint name for decoding, e.g., `valid.cer_ctc.ave.pb` |
| | | - <strong>batch_size:</strong> # batchsize of inference |
| | | |
| | | - Then you can run the pipeline to finetune with: |
| | | ```python |
| | | python infer_after_finetune.py |
| | | - Setting parameters in [infer.sh](https://github.com/alibaba-damo-academy/FunASR/blob/main/egs_modelscope/asr/TEMPLATE/infer.sh) is the same with [docs](https://github.com/alibaba-damo-academy/FunASR/tree/main/egs_modelscope/asr/TEMPLATE#inference-with-multi-thread-cpus-or-multi-gpus) |
| | | |
| | | - Decode with multi GPUs: |
| | | ```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" |
| | | ``` |
| | | - Decode with multi-thread CPUs: |
| | | ```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" |
| | | ``` |
