numpy 2.0.0
@wwh037 looks like a problem with numpy 2.0.0
I can see various errors popping up online, but not ours specifically. I did search for arraysetops
in the numpy 2.0 manual and didn't find any reference to it. Looks like the files in numpy.lib
have been overhauled and changed the access to arraysetops
.
.
I suggest for the time being, revert to numpy version 1.26
@wwh037 With numpy 2.0 the procedures we use from numpy.lib.arraysetops
have been moved to numpy
. We will make a change in the develop branch of anuga_core and the next release 3.2.
@wwh037 I have tried to fix the problem in the develop branch of anuga_core. I haven't tried the fix with numpy 2.0. Would be great if you could download the updated version and see if it works. In the meantime I will have to update our CI test to use numpy 2.0.
@wwh037 Seems there are other changes with numpy 2.0. So for the time being I would recommend reverting back to numpy 1.26
@wwh037 I only had to change one instance of np.array(obj, copy=False)
to npasarray(obj)
and that allowed ANUGA to pass all the unittests using numpy 2.0. The correction is in the latest version of the develop branch of anuga_core on this site.
