ValueError: numpy.dtype size changed, may indicate binary incompatibility. #551
Description
I am encountering an error that looks like the following. It is most likely related to NumPy compatibilities, maybe python-graphblas might not be compatible with 2.0.0?
I found an existing thread on stackoverflow, but the suggestions there did not fix the issue. Any help is appreciated!
eye = gb.Vector.from_scalar(1, n).diag()

Sorry you bumped into this! We are still working to get numpy 2 support in #546, which I think is getting close.
The error you are seeing originates from
suitesparse_graphblas, which we also recently updated to support numpy 2. This was done on conda-forge in conda-forge/python-suitesparse-graphblas-feedstock#60 , which was merged Dec 20 (about three weeks ago).I expect we'll release python-graphblas with support for numpy 2, Python 3.13, and SuiteSparse:GraphBLAS 9 in a couple-ish weeks (hopefully sooner since this is long overdue, but we'll see how many more bumps we run into). The next step is to rebuild python-suitesparse-graphblas on conda-forge for Python 3.13.
