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()
             ^^^^^^^^^
     File "/opt/anaconda3/envs/cvxpy_env/lib/python3.12/site-packages/graphblas/__init__.py", line 68, in __getattr__
       _init("suitesparse", None, automatic=True)
     File "/opt/anaconda3/envs/cvxpy_env/lib/python3.12/site-packages/graphblas/__init__.py", line 142, in _init
       from suitesparse_graphblas import ffi, initialize, is_initialized, lib

     File "suitesparse_graphblas/utils.pyx", line 1, in init suitesparse_graphblas.utils

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.
