No module named '_swigfaiss' for conda install #485

Closed hsiaoma closed 6 years ago

hsiaoma commented 6 years ago

Summary

Platform

OS: macOS 10.13.4

Faiss version:

Faiss compilation options:

Running on :

Reproduction instructions

I installed with ``` conda install faiss-cpu -c pytorch ``` and got `No module named '_swigfaiss'` error. I went into faiss directory and tried to import again, but got the same error message. It is mentioned in the trouble shooting that this error is caused by faiss not being compiled. Since I use conda install, I suppose it is not the case?
beauby commented 6 years ago

This seems to be related to (the lack of) libomp. I'll investigate further.

beauby commented 6 years ago

@ailzhang Which compiler are you using to build the faiss conda package? I'm guessing some flavor of llvm since it's dynamically linked against libomp.

Edit: It seems to be some Homebrew llvm.

beauby commented 6 years ago

@hsiaoma As a workaround for now for using the conda package on OSX, you'll need to $ brew install libomp.

Ref: #433

hsiaoma commented 6 years ago

@beauby This indeed solves my problem, thanks a lot! You can close the issue if you think it is appropriate or leave it until the conda install issue is solved.

ailzhang commented 6 years ago

Hi @beauby macOS package was built on my old laptop which is already returned. I'm not sure which compiler I used to compile it exactly. I vaguely remember have to install some llvm packages to compile but can't remember the detail. If libomp is unnecessary, I will remove it from next release. Let me know! :)

fooSynaptic commented 6 years ago

hi @beauby i got hindered by the same issue mentioned by hsiaoma and the Ref: #433 even after brew install libomp. my machine is MacOS sys and I was trying to install the latest version of faiss via conda install faiss-cpu -c pytorch can you give me some advices to fix it ?

ghost commented 6 years ago

Hi @beauby I am getting the same issue mentioned by @hsiaoma My machine is ubuntu sys and I installed only cpu version with conda by conda install faiss-cpu -c pytorch

Any help would be highly appreciated.

mdouze commented 6 years ago

@ailzhang, any comment?

ailzhang commented 6 years ago

Hi @mdman92 Could you try 'from swigfaiss_gpu import *' in $YOUR_CONDA_HOME/lib/pythonx.x/site-packages/faiss? Also could you post conda list result here?

fooSynaptic commented 6 years ago

@ailzhang I followed your instruction but the issue still happen, since I only install the cpu version, the exception showed ModuleNotFoundError: No module named 'swigfaiss_cpu'

while I change dir into the CONDA_HOME/lib/pythonx.x/site-packages/faiss and try to

import faiss

@fooSynaptic Try brew install llvm and see if it fixes the issue? It's complaining about missing libomp

fooSynaptic commented 6 years ago

@ailzhang okey, the same exception still occurred. and I can make sure both the llvm and libomp install ed successfully.

ailzhang commented 6 years ago

@fooSynaptic Could you try installing the new version and let me know if this issue still happens?

zqwangadv commented 6 years ago

I install faiss use "conda install" on a linux machine, I got the same error "ImportError: No module named _swigfaiss" when I import the faiss. How can I solve this issue???

zqwangadv commented 6 years ago

I find that the error "ImportError: No module named _swigfaiss" will be disappeared where I use the anaconda3(python3) instead of anaconda2 install faisss. Does the lastest code only support anacoda3 to install???

ailzhang commented 6 years ago

Conda env shouldn't depend on anaconda versions. It's possible that you create a python2 environment in anconda3 solves the issue as well.

I encountered the same problem. My anaconda version is Anaconda 4.2.0, system is Cents os 7. After conda install mkl, I solved this problem. However, I do not know why.....

newer mkl version is required. I've tried installing mkl 2017.0.3-0, not working. Later I tried installing mkl 2019.3-199, everything's good.

flynnzhao commented 4 years ago

It should not be so：

pip install faiss

should do：

CPU version only

conda install faiss-cpu -c pytorch

GPU version

conda install faiss-gpu cudatoolkit=8.0 -c pytorch # For CUDA8 conda install faiss-gpu cudatoolkit=9.0 -c pytorch # For CUDA9 conda install faiss-gpu cudatoolkit=10.0 -c pytorch # For CUDA10

For those who are working with pip and not conda, if you have installed it with,

pip install faiss

uninstall it. And then install faiss with,

pip install faiss-cpu --no-cache

This worked for me 👍
