Is it possible to build faiss on Alpine? In recent years there have been reports on issues with that.

I have some different approaches but something is missing:

We do support Linux: https://github.com/facebookresearch/faiss/wiki/Installing-Faiss
However, if Alpine has any specific requirements, we don't support it and support isn't planned.

@synergiator please install standard things, such as python and numpy, as specified in the error message
Maybe, you're looking for this? https://github.com/facebookresearch/faiss/blob/main/faiss/cppcontrib/docker_dev/Dockerfile

@alexanderguzhva @gtwang01 thank you both for your quick answers!

After further investigation, I think now the root issue is that faiss typically compiles well against MKL (Intel Math Kernel Library) which again is based on Fortran. There is no MKL support for Alpine afaik - therefore for example the faiss-cpu Python package includes a precompiled version of faiss for Debian/Ubuntu, but not for Alpine.

An alternative to MKL might be OpenBLAS, and the compilation even works with the below Dockerfile - unfortunately, many tests fail in the end, those who wrote them will know better why. But compilation has worked! 😆 🤦‍

@synergiator

I think now the root issue is that faiss typically compiles well against MKL

unlikely. There's a definite problem with the compilation. Are you sure that you're not missing anything? Say, something like

cmake .. \
      -DBUILD_TESTING=ON \
      -DFAISS_ENABLE_GPU=OFF \
      -DFAISS_OPT_LEVEL=axv2 \
      -DFAISS_ENABLE_C_API=ON \
      -DCMAKE_BUILD_TYPE=Release \
      -DBLA_VENDOR=OpenBLAS && \
    make -j"$(nproc)" faiss_avx2 && \
    make -j"$(nproc)" swigfaiss && \

As far as I remember, you need to build faiss (faiss_avx2 for avx2 opt level) before you build swigfaiss. It is possible that you might need swigfaiss_avx2, but I don't remember lol

on updated Dockerfile, it takes now longer time to compile, but unfortunately same failures.

FROM alpine:3.20

# 1. Install build & glibc-compat packages

      ninja \
      gcompat  # for random_r()

# 2. Ensure python points correctly

# 3. Clone & build FAISS with OpenBLAS

Same with this one as you have mentioned another option.

      build-base \
      cmake \
      git \

      py3-pip \
      py3-numpy-dev \
      openblas-dev \
      lapack-dev \
      gfortran \
      libgfortran \
      gflags-dev \
      gflags \
      ninja \
      gcompat  # for random_r()

# 2. Ensure python points correctly
RUN ln -sf /usr/bin/python3 /usr/bin/python

# 3. Clone & build FAISS with OpenBLAS
RUN git clone https://github.com/facebookresearch/faiss.git /faiss && \
    cd /faiss && \
    export FAISS_ROOT=$(pwd) && \
    mkdir build && cd build && \
    cmake .. \
      -DBUILD_TESTING=ON \

      -DFAISS_ENABLE_C_API=ON \
      -DCMAKE_BUILD_TYPE=Release \
      -DBLA_VENDOR=OpenBLAS && \
    make -j"$(nproc)" faiss_avx2 && \
    make -j"$(nproc)" swigfaiss_avx2 && \
    cd faiss/python && python setup.py build && \
    cd $FAISS_ROOT && \
    export PYTHONPATH=../build/faiss/python/build/lib/ && \
    export OMP_NUM_THREADS=1 && \
    #python -m unittest -v discover
    python -m unittest discover -s tests -p "test_*.py"
