Segmentation fault: 11

[vlad43210]

Hi, I just tried out sentence-transformers for the first time, and it gives a segmentation fault when importing:

>>> from sentence_transformers import SentenceTransformer
Segmentation fault: 11

This is on Python 3.8.12, I tried both pip install -U sentence-transformers and install from source. I have torch 1-.10.0 installed in this environment. I'd really appreciate any help you might be able to provide!

Thank you,

Vlad

Segmentation fault appears to be some memory error connected to C. I would guess that pytorch is the problem.

Can you import pytorch and transformers?

I found the solution for my problem -- I installed sentence-transformers via pip as directed but installed pandas via conda as I am used to. This causes the segmentation fault, though I do not know why. Cleaning out my environment and installing pandas from pip solved the issue. I would sugggest a small note in the README that this package is currently not compatible with conda.

I had a similar issue on Mac and re-installing numpy solved it for me.

I encountered a similar issue when trying to install sentence-transformers 2.2.2 in a Python 10 environment. The installation process failed with the segmentation fault error message. After some troubleshooting, I found a solution that worked for me.
I downgraded my Python installation from version 10 to version 8, and then I was able to install sentence-transformers 2.2.2 without any issues. It seems that there is some incompatibility between sentence-transformers and Python 10.
If you're facing a similar issue, I suggest trying this solution. Of course, downgrading your Python installation may not be ideal if you're using other packages that require Python 10.

I got the segmenrtation fault with torch 2.1.0, sentence_transformers; 2.2.2 and Python 3.9.2

@nreimers this happens with Python 3.8.12 as well. I was using docker python:3.8.12-slim-bullseye

root@266ab0ebff1c:/app# python -c "import sentence_transformers; print(sentence_transformers.__version__)"
2.2.2

from sentence_transformers import SentenceTransformer
sentences = ["This is an example sentence", "Each sentence is converted"]

model = SentenceTransformer('sentence-transformers/all-MiniLM-L6-v2')
embeddings = model.encode(sentences)
print(embeddings)

[UPDATE]
Got the same issue with Python 3.10.13

Segmentation fault

Encountered the same issue on Python 3.11 & 3.12 on Intel macOS.

[karthick1729]

I encountered similar issues. it got fixed by chaging the versions to python=3.10.0, torch=2.0.1, torchvision=0.15.2, sentence_transformer=2.2.2

[neonwatty]

In addition to @karthick1729 's suggestion i found the following downgrades also solved the issue

• python3.10
• torch==2.1.0
• torchvision==0.16.0
• sentence-transformers==2.2.2
