one possible solution: change here https://github.com/dimatura/pypcd/blob/20b032bfc729dec853ac810bceeb360f78bdc1d6/pypcd/pypcd.py#L64-L72 to:

numpy_pcd_type_mappings = [(np.dtype('float32'), ('F', 4)),
                           (np.dtype('float64'), ('F', 8)),
                           (np.dtype('uint8'), ('U', 1)),
                           (np.dtype('uint16'), ('U', 2)),
                           (np.dtype('uint32'), ('U', 4)),
                           (np.dtype('uint64'), ('U', 8)),
                           (np.dtype('int8'), ('I', 1)),
                           (np.dtype('int16'), ('I', 2)),
                           (np.dtype('int32'), ('I', 4)),
                           (np.dtype('int64'), ('I', 8))]
