Also I tried to install via pip install --no-binary :all: nmslib but the error still the same.

Versions: Python 3.8.8 pip 21.0.1

Could you please help me to figure out what are the ways to install nmslib on Apple Silicon M1? Or maybe I’m missing something.

I can get this to install using the following command: CFLAGS="-mavx -DWARN(a)=(a)" pip install nmslib Note that this seems to disable a lot of acceleration, so I wouldn’t recommend it for production.

I don’t know if this will work for you but I had tried CFLAGS="-mavx -DWARN(a)=(a)" pip install nmslib and got back this error:

  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed cleaning build dir for nmslib
Failed to build nmslib
ERROR: Could not build wheels for nmslib, which is required to install pyproject.toml-based projects

So I ran CFLAGS="-mavx -DWARN(a)=(a)" pip install --use-pep517 nmslib with the --use-pep517 flag and that worked!

I got here after trying to install nmslib on a MacBookPro (Big Sur, M1 chip).

What finally worked for me was a variation on a few of these recommendations:

I’m using conda (miniforge) to manage my environment
Neither pip install nmslib nor pip install nmslib --no-binary :all: worked
Installing from source did work but
- I needed to override the clang setting from -march=native to -mcpu=apple-a14. I did this by adding set(SIMD_FLAGS " -mcpu=apple-a14") into CMakeLists.txt but I’m sure there’s an environment variable way to do this…
- clang was still complaining about a nested macro in a #pragma message in similarity_search/src/distcomp_scalar.cc. Commenting out those two warnings (innocent) permitted everything to build (cmake .; make)
- Verified everything by running bunit (n.b. bunit looks for data in ../sample_data by default but that’s not the correct relative path from its default build location … by soft-linking it into ../ and then running there it worked)
After the library build was successful I built the python bindings and package
- In python_bindings/setup.py change c_opts['unix'].append('-march=native') to c_opts['unix'].append('-mcpu=apple-a14')
- At this point python setup.py install worked perfectly fine and installed nmslib==2.1.1 into my conda environment. Verified everything by running the tutorial example in the docs.

there’s a PR, I will merge it soon.

The only solution that worked for me was the one pointed by @8W9aG . If you are installing with Poetry also, simply write CFLAGS="-mavx -DWARN(a)=(a)" poetry add .....

Also ran into this issue on the M1 chip. Installing on a conda environment with pip install --no-binary :all: nmslib resolved it

azhx on May 5, 2021

I could install it following @drkeoni’s instructions. I hope they will be taken into account for a future release out-of-the-box compatible with M1.

lifepillar on Jan 17, 2022

@azhx I don’t maintain a conda installation, but apparently it doesn’t distinguish between Intel and m1 MAC. So, then it simply crashes. I have heard M1 can run Intel code, but, apparently, this does not work ideally. They may also remove that flag from their installation code. That is one reason why you can install from sources. When you install from sources, clearly, there is no issue with running Intel binary on M1, b/c you compile into native N1 code.
