AttributeError: 'MithralEncoder' object has no attribute 'splits_lists'

[SterDream]

When I used MithralMatmul, an error occurred. The code I used:

input1 = np.random.rand(3, 4)
input2 = np.random.rand(4)
mm = MithralMatmul(ncodebooks=4)
result = mm(input1, input2)

The error occurs on the following line:

bolt/experiments/python/vquantizers.py

Lines 610 to 612 in e7726a4

	def encode_X(self, X):
	idxs = clusterize.mithral_encode(X, self.splits_lists)
	return idxs + self.offsets

I'm sorry, but I'm not very familiar with Maddness.
Do you have any suggestions for a solution?
