How to install MEEP using conda for python 3.12 to work with gdsfactory

[Argonghost]

Hi,

I have a linux subsystem for Windows. and im trying to install MEEP in order to work with gdsfactory. I currently have gdsfactory with Python 3.12 which works. When i followed the steps to download MEEP using Conda, it creates a virtual env thats Python 3.8. I need MEEP to be installed on Python 3.12. How do i do that?
Below are the steps i followed to install MEEP

wget https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh -O miniconda.sh bash miniconda.sh -b -p miniconda3 export PATH=miniconda3/bin:$PATH ~/miniconda3/bin/conda init bash conda create -n meep -c conda-forge pymeep pymeep-extras source activate meep

This launches a virtual env thats Python 3.8, which gives many errors with gdsfactory. Also, whatever i try to do to reinstll gdsfactory using pip doesnt get reflected .

Thanks

Open a terminal and activate the environment you want to update.
conda activate meep
then tell conda to install python 3.11.9 in the current environment
conda install python=3.11.9
then voila.
From what I remember this is the latest version of python that conda currently supports. To use any later version requires a lot of work from what I remember.
To check which interpreter your environment is using, type the following

import sys
print(sys.executable)

If you're working with conda then the pip commands only works through ipython (at least it works for me) and that's because I use my conda environment as the python interpreter for my IDE (I use spyder).
If you are making changes to python through pip or through conda that are not registering that means whatever python you're running is not the one you're updating. In other words, you are probably using the system's default interpreter instead that of the environment.

Perfect!!
Worked like a gem. Yes indeed it was an issue of pip packages not being reflected in Conda (I use VSCode)

Thanks for the save!
