EnergyplusToFMU cannot work on Mac

[Qiwei QIN]

Dear all,

I have tried the EnergyPlusToFmu 3.0.0 on my Mac OS. I have tried the rununittest.py and it can create the .fmu file but cannot simulate it.

The python shell stock like the picture1 and the log.txt is as attachment.

Which master are you using to drive the FMU?

Thank you for your response quickly.

I have tried to install the PyFMI by command pip install PyFMI for Python2.7 but failed. So I have used the Anaconda for installing the package.

Right now, I found that the .fmu file has successfully created but cannot simulated by EnergyPlus 9.3.0

I wanna using Python and EnergyPlus cosimulation to fulfill a reinforcement learning control or MPC control( The model is created in python, Energyplus is like an emulated environment).  I tried using the EnergyPlusFMU version 3 runUnitTest.py.

My operation system is MacOs 10.15 and EnergyPlus is 9-3-0. Python 2.7 in Anaconda. Right now, I can see that the .fmu file has been successfully created but when going to simulation. The terminal is always like the following pictures:

Dear sir,

After checking the systems, it works. It seems that the reason is the Firewall of my system has stopped the communication between the anaconda and Energyplus. Right now I succeed.

Thanks for your help

It seems that not the reason I mentioned before, there are three versions of E+ in my Mac, I found that no matter I choose which version of E+, it always is run by E+9-2-0. The version of Energyplus 9-2-0 in my Mac is modified by the following:

https://github.com/IBM/rl-testbed-for-energyplus but not completed.

No matter what, it finally works in my systems, but I am curious about why. It seems some issues about the system variables about the PATH or something else?

Thanks

Please note that when running the unit test, the path of EnergyPlus that is provided will be used to export the IDF file as an FMU. 

To run the FMU, the EnergyPlusFMU will use the version of EnergyPlus that is found on the System Path. 

If you type energyplus in the prompt shell of your mac, then the version of EnergyPlus that will start wil be the one used by the FMU to run. That version is the one that is on your System Path
