Try this!!!
Python Functions in MATLAB
Use Python® functions in MATLAB®, function signatures, arguments
To call a Python method or function, type py. followed by the module name, function name, and arguments.
In most cases, MATLAB automatically converts input arguments into Python types. An exception is calling a Python function with keyword arguments. Use the pyargs function to pass MATLAB data to these functions.

You can call python script from matlab using the function

 system('python python_script.py');

in the same way, you can run a matlab script from python using the function os.system

 import os
print "I am in python"
os.system("matlab matlab_script.m")

What if its a python function with 2 arguments instead of a python script, how do I use system() in that case?

In R2021b, pyrun function allows you to run Python code directly from MATLAB.
Also, pyrunfile to run Python script.

I tried a simple xgboost python model and it worked well.
Maybe you did not import it in python? Is it a python error? You can check that: https://www.mathworks.com/help/matlab/matlab_external/troubleshooting-python-errors.html
You can try my example running:
preds = pyrunfile("xgboost_model.py", "preds")
You should have in output an ndarray.
