This is an\n        advanced function, and is only intended for the QuTiP user who wants to\n        add a new underlying data type to QuTiP.\n\n        Any new data type must have at least one converter function given to\n        produce the new data type from an existing data type, and at least one\n        which produces an existing data type from the new one.  You need not\n        specify any more than this, although for efficiency reasons, you may\n        want to specify direct conversions for all types you expect the new\n        type to interact with frequently.\n\n        Parameters\n        ----------\n        converters : iterable of (to_type, from_type, converter, [weight])\n            An iterable of 3- or 4-tuples describing all the new conversions.\n            Each element can individually be a 3- or 4-tuple; they do not need\n            to be all one or the other.\n\n            Elements\n            ........\n            to_type : type\n                The data-layer type that is output by the converter.\n\n            from_type : type\n                The data-layer type to be input to the converter.\n\n            converter : callable (Data -> Data)\n                The converter function.  This should take a single argument\n                (the input data-layer function) and output a data-layer object\n                of `to_type`.  The converter may assume without error checking\n                that its input will always be of `to_type`.  It is safe to\n                specify the same conversion function for multiple inputs so\n                long as the function handles them all safely, but it must\n                always return a single output type.\n\n            weight : positive real, optional (1)\n                The weight associated with this conversion.  This must be > 0,\n                and defaults to `1` if not supplied (which is fixed to be the\n              ""  cost of conversion to `Dense` from `CSR`).  It is generally\n                safe just to leave this blank; it is always at best an\n                approximation.  The currently defined weights are accessible in\n                the `weights` attribute of this object.\n                Weight of ~0.001 are should be used in case when no conversion\n                is needed or ``converter = lambda mat : mat``.\n\n        _defer : bool, optional (False)\n            Only intended for internal library use during initialisation. If\n            `True`, the full lookup tables is not built and the added types\n            will not be usable until the building is triggered elsewhere.\n        ");
