Installation

System Dependencies

PathBench requires the following system packages:

• Python 3.10+

• espeak-ng shared library

• build-essential, cmake

• libfftw3-dev, liblapack-dev

On Ubuntu 22.04:

sudo apt-get update -qq
sudo apt install python3 python3-pip python3-venv \
    build-essential cmake espeak-ng libfftw3-dev liblapack-dev -y

Make Installation

The recommended installation route uses the provided Makefile:

git clone git@github.com:karkirowle/pathbench.git
cd pathbench/tools && make
cd ..
source tools/venv/bin/activate

To change the CUDA version:

make CUDA_VERSION=12.1

For CPU-only:

make CUDA_VERSION=

Without sudo access, a containerised environment such as Docker is recommended.

Note

PathBench cannot be published to PyPI because it depends on Git-hosted forks of phonemizer and pyctcdecode.
