Automatic Circuit DisCovery

This is the accompanying code to the paper "Towards Automated Circuit Discovery for Mechanistic Interpretability".

⚡ To run ACDC, see acdc/main.py, or this Colab notebook
🔧 To see how edit edges in computational graphs in models, see notebooks/editing_edges.py or this Colab notebook
❇️ To understand the low-level implementation of completely editable computational graphs, see this Colab notebook or notebooks/implementation_demo.py

This library builds upon the abstractions (HookPoints and standardised HookedTransformers) from TransformerLens 🔎

Installation:

First, install the system dependencies for either Mac or Linux.

Then, you need Python 3.8+ and Poetry to install ACDC, like so

git clone git+https://github.com/ArthurConmy/Automatic-Circuit-Discovery.git
cd Automatic-Circuit-Discovery
poetry env use 3.10      # Or be inside a conda or venv environment
                         # Python 3.10 is recommended but use any Python version >= 3.8
poetry install

System Dependencies

🐧 Ubuntu Linux

sudo apt-get update && sudo apt-get install libgl1-mesa-glx graphviz build-essential graphviz-dev

You may also need apt-get install python3.x-dev where x is your Python version (also see the issue and pygraphviz installation troubleshooting)

🍎 Mac OS X

On Mac, you need to let pip (inside poetry) know about the path to the Graphviz libraries.

brew install graphviz
export CFLAGS="-I$(brew --prefix graphviz)/include"
export LDFLAGS="-L$(brew --prefix graphviz)/lib"

Reproducing results

To reproduce the Pareto Frontier of KL divergences against number of edges for ACDC runs, run python experiments/launch_induction.py. Similarly, python experiments/launch_sixteen_heads.py and python subnetwork_probing/train.py were used to generate individual data points for the other methods, using the CLI help. All these three commands can produce wandb runs. We use notebooks/roc_plot_generator.py to process data from wandb runs into JSON files (see experiments/results/plots_data/Makefile for the commands) and notebooks/make_plotly_plots.py to produce plots from these JSON files.

Tests

From the root directory, run

pytest -vvv -m "not slow"

This will only select tests not marked as slow. These tests take a long time, and are good to run occasionally, but not every time.

You can run the slow tests with

pytest -s -m slow

Contributing

We welcome issues where the code is unclear!

If your PR affects the main demo, rerun

chmod +x experiments/make_notebooks.sh
./experiments/make_notebooks.sh

to automatically turn the main.py into a working demo and check that no errors arise. It is essential that the notebooks converted here consist only of #%% [markdown] markdown-only cells, and #%% cells with code.

TODO

Mostly finished TODO list

[ x ] Make TransformerLens install be Neel's code not my PR

[ x ] Add hook_mlp_in to TransformerLens and delete hook_resid_mid (and test to ensure no bad things?)

[ x ] Delete arthur-try-merge-tl references from the repo

[ x ] Make notebook on abstractions

[ ? ] Fix huge edge sizes in Induction Main example and change that occurred

[ x ] Find a better way to deal with the versioning on the Colabs installs...

[ ] Neuron-level experiments

[ ] Position-level experiments

[ ] Edge gradient descent experiments

[ ] Implement the circuit breaking paper

[ x ] tracr and other dependencies better managed

[ ? ] Make SP tests work (lots outdated so skipped) - and check SubnetworkProbing installs properly (no init.pys !!!)

[ ? ] Make the 9 tests also failing on TransformerLens-main pass

[ x ] Remove Codebase under construction
