Documentation and Tutorials for Turing.jl

This repository is part of Turing.jl's website (i.e. https://turinglang.org/docs/). It contains the Turing.jl documentation and tutorials.

• The master branch contains the quarto source
• The gh-pages branch contains the html version of these documents compiled from the master branch.

Note

Due to an incompatibility between Bijectors.jl and Enzyme.jl, the docs currently must be built with Julia 1.10. You can do this either by making Julia 1.10 your default Julia version (juliaup default 1.10), or by explicitly specifying Julia 1.10 when running Quarto:

QUARTO_JULIA=$(julia +1.10 -e "println(Sys.BINDIR)")/julia quarto render

Local development

To get started with the docs website locally, you'll need to have Quarto installed. Make sure you have at least version 1.5 of Quarto installed, as this is required to correctly run the native Julia engine. Ideally, you should use Quarto 1.6.31 or later as this version fixes a bug which causes random number generation between different cells to not be deterministic. Note that as of October 2024, Quarto 1.6 is a pre-release version, so you may need to install it from source rather than via a package manager like Homebrew.

Once you have Quarto installed, you can follow these steps:

1. Clone this repository:

   git clone https://github.com/TuringLang/docs

2. Navigate into the cloned directory:

   cd docs

3. Instantiate the project environment:

   julia --project=. -e 'using Pkg; Pkg.instantiate()'

4. Preview the website using Quarto Preview:

   quarto preview

   This will launch a local server at http://localhost:4200/, which you can view in your web browser by navigating to the link shown in your terminal. Note: Avoid clicking links in the navbar while previewing locally because they will eventually lead to https links online!

5. Render the website locally:

   quarto render

   This will build the entire documentation and place the output in the _site folder. You can then view the rendered website by launching a HTTP server from that directory, e.g. using Python:

   cd _site
   python -m http.server 8000

   Then, navigate to http://localhost:8000/ in your web browser.

   Note that rendering the entire documentation site can take a long time (usually multiple hours). If you wish to speed up local rendering, there are two options available:

   • Download the most recent _freeze folder from the GitHub releases of this repo, and place it in the root of the project. This will allow Quarto to reuse the outputs of previous computations for any files which have not been changed since that _freeze folder was created.

   • Alternatively, render a single tutorial or qmd file without compiling the entire site. To do this, pass the qmd file as an argument to quarto render:

     quarto render path/to/index.qmd
     

Troubleshooting build issues

As described in the Quarto docs, Quarto's Julia engine uses a worker process behind the scenes. Sometimes this can result in issues with old package code not being unloaded (e.g. when package versions are upgraded). If you find that Quarto's execution is failing with errors that aren't reproducible via a normal REPL, try adding the --execute-daemon-restart flag to the quarto render command:

quarto render /path/to/index.qmd --execute-daemon-restart

And also, kill any stray Quarto processes that are still running (sometimes it keeps running in the background):

pkill -9 -f quarto
