In the minicourse, if you haven't prepared beforehand, please use this link to run online via Binder:

GitHub provides 120 core-hours (60 real-time hours if you use the smallest (2-core) setting) of CodeSpaces usage every month. You can run this in a codespace:

Note that you should currently start jupyter lab manually from the VSCode terminal once it's built (3-5 minutes after starting it for the first time).

If you are reading this at least 10 minutes before the course starts or you have pixi, anaconda, or miniconda installed, you will probably be best off installing miniconda. This way you will keep local edits and will have an environment to play with.

Get the repository:

git clone https://github.com/henryiii/python-performance-minicourse.git
cd python-performance-minicourse

If you have pixi, just run:

pixi run lab

If you don't have pixi (it's just a single binary written in Rust), classic instructions follow:

Download and install miniconda. On macOS with homebrew, just run brew cask install miniconda (see my recommendations).

Run:

conda env create

from this directory. This will create an environment performance-minicourse. To use:

conda activate performance-minicourse
./check.py # Check to see if you've installed this correctly
jupyter lab

And, to disable:

conda deactivate

or restart your terminal.

To keep this in sync, I'm using this to export the pixi environment into something conda/mamba can use:

pixi workspace export conda-environment -n performance-minicourse > environment.yml

Binder is using conda.
