I think this has to do with using the np.uint32 here:

laser/jb/src/sir_numpy.py

Line 78 in b066650

new_nodes = np.ones( num_slots, dtype=np.uint32 )*-1

There are a bunch of associated changes that should probably go along with this fix. They are present in jb_modulify branch, which is also installable as idmlaser==0.0.1.

[krosenfeld-IDM]

ok, that's helpful to know. It makes the most sense to me to have both @KevinMcCarthyAtIDM and myself working off of the same branch (or as close as possible) for this loop. I don't plan to change branches at this point.
