ValueError: spacy.strings.StringStore size changed, may indicate binary incompatibility. Expected 112 from C header, got 88 from PyObject about bert-extractive-summarizer HOT 12 CLOSED

Taken from here:
If you have an error mentioning spacy.strings.StringStore size changed, may indicate binary incompatibility when loading NeuralCoref with import neuralcoref, it means you'll have to install NeuralCoref from the distribution's sources instead of the wheels to get NeuralCoref to build against the most recent version of SpaCy for your system.

In this case, simply re-install neuralcoref as follows:

pip uninstall neuralcoref
pip install neuralcoref --no-binary neuralcoref

I have confirmed that all of my requirements are the same version as the project's

from bert-extractive-summarizer.

it looks like this might have been a python 3.7 problem. python 3.6 is working for me.

from bert-extractive-summarizer.

Interesting. I'll take a look this weekend to get a bug fix/new docker image.

from bert-extractive-summarizer.

I tried both examples and am getting this type of error ending with segmentation 11, I used Python 3.7, I will try with Python 3.6, interesting project!

So when I set up a conda environment for python 3.6 the thing works perfectly

from bert-extractive-summarizer.

I am guessing the 3.7 issue is related to the spacy lock we are currently in, due to limited support from neuralcoref. Probably worth making neuralcoref optional to get around issues like this.

I am using Python 3.6.3 and have the "Segmentation fault" error. (also sure about the requirements version)
The library works well on google Colab but not on the servers I am working on.

(Also re-installing the Neuralcoref library with the flags did not work for me)

from bert-extractive-summarizer.

Thanks @TheEdoardo93, I'll add those instructions to the README. @AlaFalaki, per the neuralcoref instructions, you will need to follow TheEdoarado93 instructions.

from bert-extractive-summarizer.

@dmmiller612
I tried @TheEdoardo93's instruction before asking. It did not help.
I made a new virtual environment and reinstalled the module (pip install bert-extractive-summarizer), now everything works fine. Don't know why exactly.

from bert-extractive-summarizer.

Yeah, that is strange. It is most likely a neuralcoref issue. Neuralcoref and spacy have had some issues with some versions, but the current locked versions in the readme should work. I'll see if I can reproduce.

from bert-extractive-summarizer.

This issue was due to the coreference package. This has been addressed in recent versions, allowing coreference to be an add on rather than required. Closing for now.
