Install the Qiskit SDK and Qiskit Runtime from source
Installing the Qiskit SDK from source allows you to access the current development version, instead of using the version in the Python Package Index (PyPI) repository. This lets you inspect and extend the latest version of the Qiskit code more efficiently.
Create and activate a new virtual environment
-
Create a minimal environment with only Python installed in it.
python3 -m venv /path/to/virtual/environment
python3 -m venv /path/to/virtual/environment
python3 -m venv c:\path\to\virtual\environment
-
Activate your new environment.
source /path/to/virtual/environment/bin/activate
source /path/to/virtual/environment/bin/activate
c:\path\to\virtual\environment\Scripts\Activate.ps1
Install the Rust compiler
A Rust compiler must be installed on your system to compile Qiskit. To install the Rust compiler, use the cross-platform Rust installer rustup or another install method.
Install Qiskit
Follow these steps to install Qiskit:
- Clone the Qiskit repository.
git clone https://github.com/Qiskit/qiskit.git
- Change to the
qiskit
directory.
cd qiskit
- (Optional) If you want to run tests or linting checks, install the developer requirements.
pip install -r requirements-dev.txt
- Install
qiskit
.
-
Standard install:
pip install .
-
Editable mode: In this mode, you don't need to reinstall Qiskit when there are code changes to the project.
pip install -e .
In editable mode, the compiled extensions are built in debug mode without optimizations. This affects the runtime performance of the compiled code. To build the compiled extensions with optimizations enabled, run the following command to rebuild the binary in release mode:
python setup.py build_rust --release --inplace
NoteIf you are working on Rust code in Qiskit, you need to rebuild the extension code every time you make a local change. In editable mode, the Rust extension is only built when the install command is run, so local changes you make to the Rust code are not reflected in the installed package unless you rebuild the extension by rerunning
build_rust
(with or without--release
, depending on whether you want to build in release or debug mode).
Install Qiskit Runtime
Follow these steps if you want to install Qiskit Runtime:
- Clone the Qiskit Runtime repository.
git clone https://github.com/Qiskit/qiskit-ibm-runtime.git
- Change to the
qiskit_ibm_runtime
directory.
cd qiskit_ibm_runtime
- (Optional) If you want to run tests or linting checks, install the developer requirements. We recommend using a virtual environment to avoid polluting your global Python installation.
pip install -r requirements-dev.txt
- Install
qiskit-runtime
. We recommend using a virtual environment to avoid polluting your global Python installation.
-
Standard install:
pip install .
-
Editable mode: In this mode, you don't need to reinstall Qiskit when there are code changes to the project.
pip install -e .
In editable mode, the compiled extensions are built in debug mode without optimizations.
