Look for the calls to memmove in mjtypes.py, (most of the mjdata properties have setters that call it) and do something more like that.
from mujoco-py.

@tlbtlbtlb Using memmove doesn't work for model.body_pos or model.geom_rgba. It replaces the existing values with random values -1.08420217e-19, 1.82499993e+00, etc instead of the value actually stored in val_ptr.
Is it because these properties were initialized with write=False?
from mujoco-py.

That is likely a mismatch between C float and double types. Make sure
you’re passing in the right numpy type, which is float64.
