Pyo in PsychoPy 3 -- missing?

I included a few lines using PYO in my experiment, which runs in my Anaconda environment.
When I tried to run the expeirment using PsychoPy3 (standalone) I get the response:
import pyo
ModuleNotFoundError: No module named ‘pyo’
Is that intended? I am not getting the message when using PsychoPy2 or PsychoPy2_PY3 (standalones)

As I read a recent post by Jon, I guess it is because I installed the 64 bit version for which pyo is not available. I installed the 32 bit version and pyo is there again.
