The current result is np.dtype(np.int_) which is not strictly correct. Note that the result depends on the system. To ensure stable results use may want to use np.int64 or np.int32.

/home/runner/work/sPyNNaker/sPyNNaker/spynnaker/pyNN/models/common/param_generator_data.py:116: DeprecationWarning: NumPy will stop allowing conversion of out-of-bound Python integers to integer arrays. The conversion of -1638400 to uint32 will fail in the future.
For the old behavior, usually:
np.array(value).astype(dtype)
will give the desired result (the cast overflows).
