# Python Frontend
## Installation for end-users
End-users should install `concrete-python` using `pip`:
```shell
pip install concrete-python
```
## Setup for development
Developers that want to contribute to the Concrete-Python project can use the following
approach to setup their environment.
```shell
# clone the repository
git clone https://github.com/zama-ai/concrete.git --recursive
cd concrete
# create virtual environment
cd frontends/concrete-python
make venv
# activate virtual environment
source .venv/bin/activate
# build the compiler bindings
cd ../../compilers/concrete-compiler/compiler
make python-bindings
# set bindings build directory as an environment variable
# *** NOTE ***: You must use the Release build of the compiler!
# For now, the Debug build is not compatible with concrete-python
export COMPILER_BUILD_DIRECTORY=$(pwd)/build
echo "export COMPILER_BUILD_DIRECTORY=$(pwd)/build" >> ~/.bashrc
# run tests
cd ../../../frontends/concrete-python
make pytest
```
### VSCode setup
Alternatively you can use VSCode to develop Concrete-Python:
Suppose the compiler bindings were built in `/home/zama/concrete/compilers/concrete-compiler/compiler/build`:
- Create a `.env` file in the concrete-python root directory
- Determine the absolute path of the local compiler repository, e.g. `/home/zama/concrete`. Replace this with your
path in the following two lines
- Add to it `PYTHONPATH=$(PYTHON_PATH):/home/zama/concrete/compilers/concrete-compiler/compiler/build/tools/concretelang/python_packages/concretelang_core/`
- Add to it `LD_PRELOAD=/home/zama/concrete/compilers/concrete-compiler/compiler/build/lib/libConcretelangRuntime.so`
You can now configure `pytest` in VScode and run the tests using the graphical interface.
