# ArrayFire Python Bindings
[ArrayFire](https://github.com/arrayfire/arrayfire) is a high performance library for parallel computing with an easy-to-use API. It enables users to write scientific computing code that is portable across CUDA, OpenCL and CPU devices. This project provides Python bindings for the ArrayFire library.
## Documentation
Documentation for this project can be found [over here](http://arrayfire.org/arrayfire-python/).
## Example
```python
# Monte Carlo estimation of pi
def calc_pi_device(samples):
# Simple, array based API
# Generate uniformly distributed random numers
x = af.randu(samples)
y = af.randu(samples)
# Supports Just In Time Compilation
# The following line generates a single kernel
within_unit_circle = (x * x + y * y) < 1
# Intuitive function names
return 4 * af.count(within_unit_circle) / samples
```
Choosing a particular backend can be done using `af.set_backend(name)` where name is either "_cuda_", "_opencl_", or "_cpu_". The default device is chosen in the same order of preference.
## Getting started
ArrayFire can be installed from a variety of sources. [Pre-built wheels](https://repo.arrayfire.com/python/wheels/3.8.0/) are available for a number of systems and toolkits. These will include a distribution of the ArrayFire libraries. Currently, only the python wrapper is available on PyPI. Wrapper-only installations will require a separate installation of the ArrayFire C/C++ libraries.
You can get the ArrayFire C/C++ library from the following sources:
- [Download and install binaries](https://arrayfire.com/download)
- [Build and install from source](https://github.com/arrayfire/arrayfire)
**Install the last stable version of python wrapper:**
```
pip install arrayfire
```
**Install a pre-built wheel for a specific CUDA toolkit version:**
```
pip install arrayfire==3.8.0+cu112 -f https://repo.arrayfire.com/python/wheels/3.8.0/
# Replace the +cu112 local version with the desired toolkit
```
**Install the development source distribution:**
```
pip install git+git://github.com/arrayfire/arrayfire-python.git@master
```
**Installing offline:**
```
cd path/to/arrayfire-python
python setup.py install
```
Rather than installing and building ArrayFire elsewhere in the system, you can also build directly through python by first setting the `AF_BUILD_LOCAL_LIBS=1` environment variable. Additional setup will be required to build ArrayFire, including satisfying dependencies and further CMake configuration. Details on how to pass additional arguments to the build systems can be found in the [scikit-build documentation.](https://scikit-build.readthedocs.io/en/latest/)
**Post Installation:**
If you are not using one of the pre-built wheels, you may need to ensure arrayfire-python can find the installed arrayfire libraries. Please follow [these instructions](https://github.com/arrayfire/arrayfire-python/wiki) to ensure that arrayfire-python can find the arrayfire libraries.
To run arrayfire tests, you can run the following command from command line.
```
python -m arrayfire.tests
```
