Concrete Numpy is an open-source set of tools which aims to simplify the use of fully homomorphic encryption (FHE) for data scientists.
With Concrete Numpy, data scientists can implement machine learning models using a subset of numpy that compiles to FHE. They will be able to train models with popular machine learning libraries and then convert the prediction functions of these models to FHE with concrete-numpy.

For end users
Installation
The preferred way to use concrete-numpy is through docker. You can get the concrete-numpy docker image by pulling the latest docker image:
docker pull zamafhe/concrete-numpy:latest
To install Concrete Numpy from PyPi, run the following:
pip install concrete-numpy
You can find more detailed installation instructions in installing.md
A simple example: numpy addition in FHE
import concrete.numpy as hnp
def add(x, y):
return x + y
inputset = [(2, 3), (0, 0), (1, 6), (7, 7), (7, 1), (3, 2), (6, 1), (1, 7), (4, 5), (5, 4)]
compiler = hnp.NPFHECompiler(add, {"x": "encrypted", "y": "encrypted"})
print(f"Compiling...")
circuit = compiler.compile_on_inputset(inputset)
examples = [(3, 4), (1, 2), (7, 7), (0, 0)]
for example in examples:
result = circuit.run(*example)
print(f"Evaluation of {' + '.join(map(str, example))} homomorphically = {result}")For developers
