Installation

Basic Installation (Python-only)

pip install pufferlib-core

Installation with C++/CUDA Extensions

To enable the pufferlib._C extensions (required for advanced features like CUDA advantage computation):

# First install torch
pip install torch

# Then install with extensions
PUFFERLIB_BUILD_EXT=1 pip install pufferlib-core[ext]

Or you can install the dependencies and build in separate steps:

# Install with extra dependencies
pip install pufferlib-core[ext]

# Then rebuild with extensions
PUFFERLIB_BUILD_EXT=1 pip install --upgrade --force-reinstall --no-deps pufferlib-core

Usage

After installation with extensions, you should be able to import the C extensions:

import pufferlib
from pufferlib import _C  # This will only work if extensions were built

Development

To build extensions in development mode:

PUFFERLIB_BUILD_EXT=1 python setup.py build_ext --inplace
