Hello. I have some problem installing MatlabEngine on Python in Jupyter Notebook. I think I am installing the module to a wrong environment but I cannot find a solution. Any feedback is appreciated. Thanks.

Even with some warnings, it appears the installation is finished.
However, with
conda list
Jupyter says
# packages in environment at /usr/local/anaconda3:
#
# Name Version Build Channel
(skipped)
markdown 3.4.1 pypi_0 pypi
markupsafe 1.1.1 py39h9ed2024_0

matplotlib-base 3.4.3 py39h0a11d32_0
matplotlib-inline 0.1.2 pyhd3eb1b0_2
(skipped)
I do not see MatlabEngine. I am concerened that I am not intalling the module to the right environment.
Indeed, when I use
!conda list
Jupyter says
# packages in environment at /Users/yasunorihayashi/opt/anaconda3:
#
# Name Version Build Channel
make 4.3 h22f3db7_1 conda-forge

matplotlib-base 3.5.2 py38h1b6b9d1_1 conda-forge
matplotlib-inline 0.1.3 pyhd8ed1ab_0 conda-forge
I do see matlabengineforpython. I see it when I performed conda list from Terminal.
I also tried to use
python setup.py install
Then Jupyter Notebook gives the following error message.
File "/var/folders/tn/ndq7xwrx71vgqpzjb_rl91gc0000gn/T/ipykernel_59616/1000827859.py", line 1

SyntaxError: invalid syntax
Thank you again for your feedback.

Hi Yasunori,
The issue you're experiencing is likely due to installing the matlabengineforpython package in a different Python environment than the one Jupyter Notebook is using. Here's how you can resolve this:
1.Verify the Python Environment in Jupyter Notebook: First, check which Python environment Jupyter Notebook is using. You can do this by running the following command in a new Jupyter cell:pythonCopy codeimport sys
print(sys.executable)
This will show the path to the Python executable that Jupyter is using.
2. Install MATLAB Engine in the Correct Environment:If the paths don't match, you need to install the MATLAB Engine API in the environment that Jupyter is using.
3.Use pip Instead of setup.py (Optional):If you continue to encounter warnings with setup.py, you can try using pip to install the package. First, ensure you are in the correct environment, then run:bashCopy codepip install .This command installs the package in the current directory, which should be the MATLAB engine's Python directory.
Hope this helps.
