Installing Faiss

Installing Faiss · facebookresearch/faiss Wiki (github.com)

The basic requirements are:

- a C++11 compiler (with support for OpenMP support version 2 or higher),

- a BLAS implementation (we strongly recommend using Intel MKL for best

performance).

The optional requirements are:

- for GPU indices:

  - nvcc,

  - the CUDA toolkit,

- for the python bindings:

  - python 3,

  - numpy,

  - and swig.

## Step 1: invoking CMake

 

sudo cmake -B build . -DFAISS_ENABLE_GPU=OFF -DPython_EXECUTABLE=/home/pang/anaconda3/bin/python

in Path/faiss/tests/CMakeLists.txt   line change URL as  PATH/googletest-release-1.10.0.tar.gz

download linker  ---   https://github.com/google/googletest/archive/release-1.10.0.tar.gz

 

$ sudo make -C build -j faiss

 

 

sudo make -C build -j swigfaiss

 

sudo make -C build install

 

cd build/faiss/python && python setup.py install

 

 

 

 

Python

------

To import Faiss in your own Python project, you need the files

```

__init__.py

swigfaiss.py

_swigfaiss.so

```

to be present in a `faiss/` directory visible in the PYTHONPATH or in the

current directory.

Then Faiss can be used in python with

```python

import faiss

```
