How do I solve this Python error message "No module named 'numpy' " in MATLAB Online ?
显示 更早的评论
I tried this block "CustomPythonModelPredict" by Statistics and Machine Learning Toolbox.
See below link.
I opened slexCustomPythonModelPredictExample.slx as this documentation.
I executed PredictResponsesUsingCustomPythonModelExample.mlx but
I got this error.
I looked into MATLAB Answer community and found similar posts but I couldn't figure out the solution.
Also I did this command
system('python -m pip install numpy')
but
/usr/bin/python: No module named pip
shows up. I'm not sure....
In the case of MATLAB Online, how do you solve this issue?
It'd be nice if you could give me any advice.
Here is the result I did pyversion command.
>>pyversion
version: '3.10'
executable: '/usr/bin/python3'
library: 'libpython3.10.so.1.0'
home: '/usr'
isloaded: 1

Hi 翼,
I understand you're encountering an error related to numpy not being installed when using MATLAB Online. This is because libraries like numpy are not included with the default Python installation and require separate installations, which isn't feasible in MATLAB Online.
As a workaround, I recommend installing numpy on your local machine where MATLAB desktop is installed. Once numpy is installed, you can then work with the slexCustomPythonModelPredictExample.slx and other related files without encountering this issue.
You can refer to the following MATLAB Answer to understand more about numpy in MATLAB : https://www.mathworks.com/matlabcentral/answers/427187-problem-with-python-numpy.
