Run pickle file in matlab

I have machines learning model developed by python and saved as pickle file how can i run it in matlab

The questions contains too few information to be answered. What exactly is your problem?

This shows how to load a pickle file into MATLAB:

pickle = py.importlib.import_module('pickle');
fh = py.open('data.pkl', 'rb')
P = pickle.load(fh);    % pickle file loaded to Python variable
fh.close();
mP = py2mat(P);         % pickle data converted to MATLAB native variable

The last line uses the py2mat.m utility. I tested this with the file data.pkl , created with this Python program,

#!/usr/bin/env python3
import pickle
import numpy as np
cm = np.array([[2., 3],[0, 1]]) - np.eye(2)*1j
a_list = ['this', 'is', 'a', 'complex', 'matrix', cm]
a_dict = { 1 : 1, 2 : 'two', 'three' : 3}
an_int = 42
some_bytes = b'1ee50ffe2fb5104144142f001a8ca94ae56b90cf'
X = np.arange(12,dtype=np.float16).reshape(3,4)
P = {
    'a_list' : a_list,
    'a_dict' : a_dict,
    'an_int' : an_int,
    'some_bytes' : some_bytes,
    'X' : X,
    }
with open('data.pkl', 'wb') as fh:
pickle.dump(P, fh, pickle.HIGHEST_PROTOCOL)

which comes from Section 7.13, "Pickle Files", from my book Python for MATLAB Development.

However this merely loads the contents of the pickle file. Running the machine learning model in MATLAB is something else entirely.

@Al Danial, can you help with running the pickle-loaded machine learning model in matlab then?

Thank you eitherway!
