macOS Tahoe 26.3.1 with `brew install python@3.13`

[JanX2]

Thank you for developing exactly what I was looking for. I tried to get this to run on a pretty vanilla macOS Tahoe 26.3.1 after running brew install python@3.13, but I’m still getting the message that I need to do that after trying to install the model from the UI. Any ideas how to debug this?

Seems like an older version of Python is still used. I can't seem to be able to find a way to change that. I am sure 3.13 is installed.

Edit: I don’t know why my previous search attempts had been unsuccessful, but today I tried again and found:

So…

export PATH="$(brew --prefix)/opt/python@3.13/libexec/bin:$PATH"
jan@Mac-mini ~ % which python3
/opt/homebrew/opt/python@3.13/libexec/bin/python3

It doesn’t survive the end of the terminal session though. So I had to add the line to "~/.zshrc"

…
export PATH="$(brew --prefix)/opt/python@3.13/libexec/bin:$PATH"

I’m still getting the same message from SharpGlass. A different environment?

brew install miniconda
eval "$(conda "shell.$(basename "${SHELL}")" hook)"
conda create -n sharp python=3.13
conda activate sharp
cd […]/ml-sharp
pip install -r requirements.txt
sharp --help

"~/.zshrc" needs to canton this now:

export PATH="$(brew --prefix)/opt/python@3.13/libexec/bin:$PATH"
eval "$(conda "shell.$(basename "${SHELL}")" hook)"

Error message agin. This time about a missing "ml-sharp" directory. Copied that manually to the SharpGlass bundle and then in a new Terminal session:

(base) jan@Mac-mini ~ % conda activate sharp                               
(sharp) jan@Mac-mini ~ % /Users/dev/Desktop/SharpGlass/dist/SharpGlass.app/Contents/MacOS/SharpGlass

Finally SharpGlass was up and running!
