Install the Python Package

You can select one of the following methods to install the Python package.

Method 1 (From pre-compiled wheels)

Hint

This method supports x86_64, arm64 (e.g., Mac M1, 64-bit Raspberry Pi), and arm32 (e.g., 32-bit Raspberry Pi).

pip install sherpa-onnx

To check you have installed sherpa-onnx successfully, please run

python3 -c "import sherpa_onnx; print(sherpa_onnx.__file__)"

which sherpa-onnx
sherpa-onnx --help

ls -lh $(dirname $(which sherpa-onnx))/sherpa-onnx*

Method 2 (From source)

git clone https://github.com/k2-fsa/sherpa-onnx
cd sherpa-onnx
python3 setup.py install

git clone https://github.com/k2-fsa/sherpa-onnx
export SHERPA_ONNX_CMAKE_ARGS="-DSHERPA_ONNX_ENABLE_GPU=ON"
cd sherpa-onnx
python3 setup.py install

Method 3 (For developers)

git clone https://github.com/k2-fsa/sherpa-onnx
cd sherpa-onnx
mkdir build
cd build

cmake \
  -DSHERPA_ONNX_ENABLE_PYTHON=ON \
  -DBUILD_SHARED_LIBS=ON \
  -DSHERPA_ONNX_ENABLE_CHECK=OFF \
  -DSHERPA_ONNX_ENABLE_PORTAUDIO=OFF \
  -DSHERPA_ONNX_ENABLE_C_API=OFF \
  -DSHERPA_ONNX_ENABLE_WEBSOCKET=OFF \
  ..

make -j
export PYTHONPATH=$PWD/../sherpa-onnx/python/:$PWD/lib:$PYTHONPATH

git clone https://github.com/k2-fsa/sherpa-onnx
cd sherpa-onnx
mkdir build
cd build

cmake \
  -DSHERPA_ONNX_ENABLE_PYTHON=ON \
  -DBUILD_SHARED_LIBS=ON \
  -DSHERPA_ONNX_ENABLE_CHECK=OFF \
  -DSHERPA_ONNX_ENABLE_PORTAUDIO=OFF \
  -DSHERPA_ONNX_ENABLE_C_API=OFF \
  -DSHERPA_ONNX_ENABLE_WEBSOCKET=OFF \
  -DSHERPA_ONNX_ENABLE_GPU=ON \
  ..

make -j
export PYTHONPATH=$PWD/../sherpa-onnx/python/:$PWD/lib:$PYTHONPATH

Hint

You need to install CUDA toolkit. Otherwise, you would get errors at runtime.

You can refer to https://k2-fsa.github.io/k2/installation/cuda-cudnn.html to install CUDA toolkit.

Check your installation
