Python script changes are not updated in MATLAB

I am trying to use MATLAB with some Python integration. However, when I want to apply some changes to the python scripts/functions I need to restart MATLAB to use the updated version.
I have seen some threads/replies from the past but I was not sure if there is a new way to reload the scripts or clear old information.
(matlab script)
clc
clear
clear workspace
pyenv(Version = "C:\Users\m85830ak\Python\Matlab-python\.venv\Scripts\python.exe");
fun = @trial;
x0 = [150,120e5,7850000.0]
output = fun(x0)
A=[];
b=[];
Aeq=[];
beq=[];
lb = [150,74e5,74e5];
ub = [530,300e5,300e5];
[x,fval]= fmincon(fun,x0,A,b,Aeq,beq,lb,ub)
trial.m (matlab function file)
function a = trial(x)
a=py.matlab_file.turbine(x(1),x(2),x(3));
a = -a;
matlab_file.py (Python script)
from pyfluids import Fluid, FluidsList, Input
def turbine(tin, pin, pout):
ntur = 85
m=100
turb_out = (
Fluid(FluidsList.CarbonDioxide)
.with_state(Input.temperature(tin), Input.pressure(pin))
.expansion_to_pressure(pout, ntur)
)
turb_inlet = Fluid(FluidsList.CarbonDioxide).with_state(
Input.temperature(tin), Input.pressure(pin)
)
delta_h = turb_inlet.enthalpy - turb_out.enthalpy
w_tur = delta_h * m
return w_tur

clear classes at the beginning of the script and
function a = trial(x)
mf = py.importlib.import_module("matlab_file");
py.importlib.reload(mf);
% y =[9, 4, 7, 5, 7, 4, 1, 5, 2, 3, 4];
a=mf.SQPOPT(x);
this reload is working.

py.reload(py.matlab_file);
Try using py.reload()

No module or function named 'reload'.
Error in untitled (line 6)
py.reload();
I tried py.reload(matlab_file) as well. Both gave this error
