I have installed PyFMI library and trying to load a fmu created by GT-Suite in python.
I am following this tutorial of jmodelica :
https://jmodelica.org/pyfmi/tutorial.html
# Import the load function (load_fmu)
from pyfmi import load_fmu
this set gives a warning
Could not find cannot import name 'radau5' from 'assimulo.lib' (C:\Users\chinn\Anaconda3\lib\site-packages\assimulo\lib\__init__.py)
Could not find cannot import name 'dopri5' from 'assimulo.lib' (C:\Users\chinn\Anaconda3\lib\site-packages\assimulo\lib\__init__.py)

When I try to load the fmu model
#Load the FMU
model = load_fmu('AHUdirectRPm.fmu')
I get an error
Traceback (most recent call last):

TypeError: latin_1_encode() argument 1 must be str, not bytes
Can someone help me with this. What to do?

Installing the pyfmi package with pip is giving the error.All the dependencies have to be downloaded correctly. Installing through conda doesn't require all this. Installed through conda by
conda install -c conda-forge pyfmi
This has worked well for me
