The compiler handles the encryption and decryption process when
.predict is called with
execute_in_fhe set to
True . It firsts encrypts the inputs, then runs the inference on them in FHE and finally decrypts the results.
For now, it is not yet possible to manually call each one of those steps separately. However, Concrete ML’s next release will make this feature available. Until then, you can still test several models using FHE, as this aforementioned process is done transparently.
