Troubles accessing actual ciphertext (attribute "parts") from helib::Ctxt

[lutonelli]

I'd like to access directly to the numbers composing the ciphertext Ctxt, but reading the documentation I can't seem to find anything that can help me.

I have an object Ctxt containing the ciphertext of a vector representing an image; I understand that the real ciphertext is stored in the attribute "parts" of the object, but there is no getter method to access this attribute.

I need these numbers in order to create a torch::Tensor and train a neural network, obviously there is no direct method to convert an object of type helib::Ctxt to a torch::Tensor.

What am I missing? Thanks in advance for the help.
