Running python script in Matlab: importError: no module named requests

Hi!

Im trying to run a python script in Matlab through: system('python path/fileName.py');

But i'm getting the following error:

"import requests ImportError: No module named requests".

After some reading at the forums i redefined the "pyversion"-path as seen below:

The python script is containing the following libraries:

"import requests import datetime import json"

By comparing the pyversion.library to the path of the pip-installed library "requests" i can see a differense:

path of installed 'request': Location: /Users/Erl3nd/opt/anaconda3/lib/python3.7/site-packages.

How to i redefine the library definition in pyversion?

or is it another way to import the result of the pythonscript?

pls help me :)

Hi,

I encountered a problem like this and here are some of the ways I handled it. You can try these and see if it solves your problem.

• Add the following line in your MATLAB code

py.sys.setdlopenflags(int32(10)); 
py.importlib.import_module('ssl');

If you are trying to run a python script filename.py and it exist in your path, add this in the following line

py.importlib.import_module('filename');

Then run your python code.

• You can set a LD_PRELOAD environment variable first to launch MATLAB by running the following in your terminal. Something like this

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6 matlab

Then run your code

Hope this helps:)

Thanks for helping.

it did not quite solve the problem...

I solved it by dowloading the newest matlab version 2020b, and used the "pyenv" function to set the executable path.

in addtidion, i added the .py-file in the same folder as the matlab-script, and include "mod = py.importlib.import_module('requests')" before the system function.
