Question

All of a sudden I'm getting this error. please help. I did pip install flair

Update: flair is importing gensim which is importing scipy. On April-2-24, scipy removed the triu from linalg module. from flair.data import Sentence is failing. As it is a key component, pretty much all of flair code in our project is failing.

already having this issue too

Hi all,

Gensim is aware of this issue and already merged their patch, see https://github.com/piskvorky/gensim/issues/3525

As long as they haven't released, I suggest you follow their hotfix of pinning scipy = "<1.13.0"

[MatrixRanger98]

How can this simple issue not be fixed yet? It seems that changing the import to from numpy import triu fixes everything.

[helpmefindaname]

@MatrixRanger98 as noted on the comment above, this is fixed but gensim didn't release it already.

Well yes but if you don't want other packages to be affected, it is neater to install the develop branch of gensim:

pip install git+https://github.com/piskvorky/gensim.git@develop

[cobycloud]

still observing this issue on latest python 3.10 builds

[david-waterworth]

Yeah @cobycloud it wont be properly "fixed" until the next version of gensim is uploaded to PyPI. Ideally imo they would either have fixed this ages ago when scipy first deprecated triu, or at the very least pushed out a single patch of the current version, but instead they've added the fix to the list of things that will make it into the next release whenever that is.
