ONNXRuntime-python

Install funasr-onnx

install from pip

pip install -U funasr-onnx
# For the users in China, you could install with the command:
# pip install -U funasr-onnx -i https://mirror.sjtu.edu.cn/pypi/web/simple
# If you want to export .onnx file, you should install modelscope and funasr
pip install -U modelscope funasr
# For the users in China, you could install with the command:
# pip install -U modelscope funasr -i https://mirror.sjtu.edu.cn/pypi/web/simple

or install from source code

git clone https://github.com/alibaba/FunASR.git && cd FunASR
cd funasr/runtime/python/onnxruntime
pip install -e ./
# For the users in China, you could install with the command:

result = model(wav_path)
print(result)
  • model_dir: model_name in modelscope or local path downloaded from modelscope. If the local path is set, it should contain model.onnx, config.yaml, am.mvn
  • batch_size: 1 (Default), the batch size duration inference
  • device_id: -1 (Default), infer on CPU. If you want to infer with GPU, set it to gpu_id (Please make sure that you have install the onnxruntime-gpu)
  • quantize: False (Default), load the model of model.onnx in model_dir. If set True, load the model of model_quant.onnx in model_dir
  • intra_op_num_threads: 4 (Default), sets the number of threads used for intraop parallelism on CPU

Input: wav formt file, support formats: str, np.ndarray, List[str]

Output: List[str]: recognition result
