Complex Weights Not Properly Saved in Network Checkpoints

[tobiaswiener]

I have come across an issue where complex weights in network checkpoints are not being saved properly. Currently, only the real parts of the complex numbers are saved and the imaginary parts are discarded. This behavior was encountered when using the write_network_checkpoint method of the OutputManager class.

Do you use a line like

outp.write_network_checkpoint(t, psi.get_parameters())

to write the checkpoints?

If yes, psi.get_parameters() returns a list where the real and imaginary parts of the parameters are concatinated, i.e., you will get a list of real numbers also for complex-valued parameters. Can you check whether this is what happens?
