bqskitrs

Native code for BQSKit

bqskitrs is a Python package that implements circuit instantiation and simulation to accelerate BQSKit.

Installing bqskitrs

You can often install bqskitrs via PyPi with pip:

pip install bqskitrs

this will use pre-built wheels. Sometimes wheels are not available, so you must build from source.

Building bqskitrs

Linux

It's best to build and install the manylinux version with the provided docker container:

git clone https://github.com/BQSKit/bqskitrs.git --recursive
cd bqskitrs
docker run -e OPENBLAS_ARGS="DYNAMIC_ARCH=1" --rm -v $(pwd):/io edyounis/bqskitrs-manylinux:1.1 build  --release --features=openblas --compatibility=manylinux2014
pip install --no-index --find-links=target/wheels bqskitrs

MacOS

Make sure the version of pip you have is at least 20.0.2. You can check via pip -V and upgrade via python3 -m pip install -U pip.

First, install the dependencies. We use homebrew here, which is what we build the official package against.

brew install gcc ceres-solver eigen lapack

Once that is complete you should then install Rust like as follows:

curl https://sh.rustup.rs -sSf | sh -s -- -y

Then clone and enter enter the bqskitrs directory:

git clone https://github.com/BQSKit/bqskitrs.git --recursive
cd bqskitrs

Then build the wheel (package file) with maturin:

pip install -U setuptools wheel maturin
maturin build --features="accelerate" --release

If you encounter issues on an intel x86 Mac computer with a message like "rust failed to run custom build command for cxx', you may need to run the following build command instead:

MACOSX_DEPLOYMENT_TARGET=11.0 maturin build --features="accelerate"

Finally install the wheel that you built:

pip install --no-index --find-links=target/wheels bqskitrs

Once it is done installing the wheel, verify that the installation succeeded by running

python3 -c 'import bqskitrs'

It should not print anything out nor give any error.

Windows

Make sure the version of pip you have is at least 20.0.2. You can check via pip -V and upgrade via python3 -m pip install -U pip.

Download and install rust via the installer found at https://rustup.rs/. Accept all of the defaults.

Close your shell and open a new one (this updates the enviroment).

Then install cargo-vcpkg, which will help install dependencies for us. You can install it via

cargo install cargo-vcpkg

cargo is installed with Rust so this should "just work".

Then clone and enter enter the bqskitrs directory:

git clone https://github.com/BQSKit/bqskitrs.git --recursive
cd bqskitrs

Then build the dependencies with vcpkg.

cargo vcpkg build

This will take quite a while.

Then build the wheel (package file) with maturin:

python -m pip install maturin
python -m maturin build --interpreter $(which python) --features="openblas,openblas-src/system" --release

Finally install the wheel that you built:

pip install --no-index --find-links=target/wheels bqskitrs

Once it is done installing the wheel, verify that the installation succeeded by running

python3 -c 'import bqskitrs'

It should not print anything out nor give any error.
