TypeError: 'numpy._DTypeMeta' object is not subscriptable

[sjbeskur]

Tried running the example script but I get this strange error when trying to import LightGlue

from lightglue import LightGlue 
.. 
.. <stack trace>
TypeError: 'numpy._DTypeMeta' object is not subscriptable

Seems to be using some typed implementation of numpy? Any guidance would be greatly appreciated.

forget it .. this is an issue with mismatched version of OpenCV / Numpy

this fixed it:

sudo apt remove python3-numpy && pip3 install numpy.

in case anyone cares

What versions cause a conflict?

I was using version 4.6 of OpenCV but I didn't check what version of numpy I had installed (terribly sorry).
I updated both to the following:

import cv2 as cv
import numpy as np
np.version.version
'1.26.0'

cv.version.opencv_version
'4.8.1.78'

Everything seems to work fine
