Hello everyone! I am trying to run a simulation with PythonPlugin within EnergyPlus. I already tried with 9.6 version of EnergyPlus and it works if you copy the required python libraries into "C:\EnergyPlusV9-6\python_standard_lib" directory. On the other hand, when moving to the latest version of EnergyPlus (v23.1 or even 22.2) the SAME worklow doesn't work. When running the co-simulation from EnergyPlus, I got the following error about pandas library.

** Severe  ** Failed to import module "PythonPlugin_file"    **   ~~~   ** Python error description follows:

I tried to switch to different pandas versions but it's still giving this error. Btw I am using Spyder of Anaconda so maybe the problem would be that I'm not using Python interface. Otherwise, which do you think is the source of the error? Thank you in advance
