Running encodeFrac and display ValueError: Buffer dtype mismatch, expected 'double' but got 'float'

[lilvmy]

When I use the new version of Pyfhel, for example pip install Pyfhel def encode_matrix(HE, matrix): # Base case: if the matrix is one-dimensional, directly apply encodeFrac to each element. if matrix.ndim == 1: return np.array([HE.encodeFrac(matrix)]) # Recursive case: apply encode_matrix to each sub-array. else: return np.array([encode_matrix(HE, sub_matrix) for sub_matrix in matrix]) HE = Pyfhel() ckks_params = { "scheme": "CKKS", "n": 214, "scale": 240, "qi_sizes":[60,40,40,40,60] }

HE.contextGen(**ckks_params) HE.keyGen() HE.rotateKeyGen() HE.relinKeyGen() a = np.array([[[1.0,2.4,3.6],[4.2,5.5,6.7]],[[2.3,3.4,4.8],[5.2,6.5,7.8]]]) b = encode_matrix(HE, matrix) This code runs a error: return np.array([HE.encodeFrac(matrix)]) File "Pyfhel/Pyfhel.pyx", line 742, in Pyfhel.Pyfhel.Pyfhel.encodeFrac ValueError: Buffer dtype mismatch, expected 'double' but got 'float' So how do I solve this problem
