How to run Python script in MATLAB?

I'm trying to run python script using MATLAB

The python script code.py is used for Saving Model Weights and Architecture Together and exist in the following link (the 3'rd code)

https://machinelearningmastery.com/save-load-keras-deep-learning-models/

The Python script is as follows

# MLP for Pima Indians Dataset saved to single file
from numpy import loadtxt
from keras.models import Sequential
from keras.layers import Dense
# load pima indians dataset
dataset = loadtxt("pima-indians-diabetes.csv", delimiter=",")
# split into input (X) and output (Y) variables
X = dataset[:,0:8]
Y = dataset[:,8]
# define model
model = Sequential()
model.add(Dense(12, input_dim=8, activation='relu'))
model.add(Dense(8, activation='relu'))
model.add(Dense(1, activation='sigmoid'))
# compile model
model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])
# Fit the model
model.fit(X, Y, epochs=150, batch_size=10, verbose=0)
# evaluate the model
scores = model.evaluate(X, Y, verbose=0)
print("%s: %.2f%%" % (model.metrics_names[1], scores[1]*100))
# save model and architecture to single file
model.save("model.h5")
print("Saved model to disk")

But when i run it in MATLAB using the following command;

[status,result]=system('python script.py')

I get the following error.

result =

     Importing the numpy C-extensions failed. This error can happen for
     many reasons, often due to issues with your setup or how NumPy was
     installed.

     Please note and check the following:
     
       * The Python version is: Python3.8 from "C:\Users\admin\anaconda3\python.exe"
       * The NumPy version is: "1.19.2"
     
     and make sure that they are the versions you expect.
     Please carefully study the documentation linked above for further help.

To call Python modules in MATLAB, you must have a supported version of the reference implementation (CPython) installed on your system. MATLAB supports versions 2.7, 3.6, 3.7, and 3.8

You can refer to the post here to learn about how to configure your system to use Python.
