This seems to be related to (the lack of) libomp. I'll investigate further. |
|
@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 This indeed solves my problem, thanks a lot! You can close the issue if you think it is appropriate or leave it until the |

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. |

@ailzhang, any comment? |

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? |

@ailzhang I followed your instruction but the issue still happen, while I change dir into the

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

no activity, closing. |

I encountered the same problem. My anaconda version is Anaconda 4.2.0, system is Cents os 7. |

It should not be so：pip install faiss should do：CPU version onlyconda install faiss-cpu -c pytorch GPU versionconda install faiss-gpu cudatoolkit=8.0 -c pytorch # For CUDA8 link: https://github.com/facebookresearch/faiss/blob/master/INSTALL.md |

conda install mkl=2019.3=199 |

For those who are working with pip and not conda, if you have installed it with,
uninstall it. And then install faiss with,
This worked for me 👍 |
This worked for me.Thank you |

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?The text was updated successfully, but these errors were encountered:
