I'm currently using Matlab R2020a with Python 3.8 which is seen by Matlab as the following code shows:
pe = pyenv;
pe.Version
ans =
"3.8"
My problem consits in importing python libraries. As the textwrap example shows, I tried to import the libraries in the following way:
tf = py.importlib.import_module('tensorflow')
keras = py.importlib.import_module('tensorflow.keras')
py.importlib.import_module('keras.models.load_model')
K = py.importlib.import_module('keras.backend')
np = py.importlib.import_module('numpy')
py.importlib.import_module('numpy.array')
py.importlib.import_module('numpy.hstack')
py.importlib.import_module('numpy.backend')
The problem is that I get the same error for all of them. For simplicity I share only the error related to the first module:
Error using <frozen importlib>_find_and_load_unlocked
(line 973)
Python Error: ModuleNotFoundError: No module named
'tensorflow'
Error in <frozen importlib>_find_and_load (line 991)
Error in <frozen importlib>_gcd_import (line 1014)
Error in __init__>import_module (line 127)
I even tried to import the libraries in the following way:
import py.numpy
But it does not work. What is my mistake?

Verify that the libraries are in the python sys.path with:
py.sys.path
If not, you can add the library reference with something like this, (for me working on Linux atleast):
P = py.sys.path
insert(P, int32(0), "/homes/David/PycharmProjects");

I understand that you are trying import python libraries inside MATLAB.
Please refer to the Understanding Python and MATLAB import Commands documentation for more details.

I have the same issue and that reference does not help solve the problem
