Changes in python function does not reflect in Simulink.

I have a simulink model that contains a matlab function, which instead calls a python function (test) in a python file (py_sim_test.py) using the following code.
function x = myfcn(u)
x = 0;
coder.extrinsic('py.py_sim_test.test')
x = py.py_sim_test.test(u);
end
The python function (test) performs some basic numeric operation. I am able to run the simulation with desired output. But if I change the numeric operation in the python function, then this change is not reflected when I run the simulation again.

I have the same problem as well. If you do not necessarily need to run your Python code as "coder.extrinsic", the "pyrunfile(filename.py)" can solve this problem. If not, you need to restart MATLAB every time you change the Python code. If you do not want to restart MATLAB manually every time, you can use this few lines of code in your .m file:
