fix: no more deadlock

the problem was that np defautls to flaot64 and I use float32 everywhere
else so when concatenating it with the other vectors, the whole thing
becomes np.float64. This would create a 4 bytes offset for each element of
the vector at each reset.
This would destroy the order of elements and fill the pipe up until it
reaches the max size.
