Error in running the script generate_biphoton_wavefunction.py

      I am trying to run the SFWM example. I did all the steps but in step 5 which is the running of the python code, I am getting the following error:

      ImportError: cannot import name 'mrr_biphoton_wavefunction' from 'qinterconnect.solver' (C:\Program Files\Lumerical\v222\api\python\qinterconnect\solver.cp39-win_amd64.pyd)

      I just tested this example and it works fine. Please make sure you have the latest version of the software and have qINTERCONNECT license.

      Thank you for the response. Yes, I installed the 2023 version and it worked.

      I also encountered this problem：

      ImportError: cannot import name 'mrr_biphoton_wavefunction' from 'qinterconnect.solver' (C:\Program Files\Lumerical\v231\api\python\qinterconnect\solver.cp39-win_amd64.pyd)

      But the version I am using is 2023 R1. And the case 'Spontaneous Parametric Down Conversion (SPDC) Photon Source' can operate normally.

      Probably you need to install the latest version, as two of us tested successfully.
