pyvene: Causal Interventions for Neural Networks

pyvene is Stanford NLP's library for performing causal interventions on PyTorch models. It provides a declarative, dict-based framework for activation patching, causal tracing, and interchange intervention training - making intervention experiments reproducible and shareable.

GitHub: stanfordnlp/pyvene (840+ stars) Paper: pyvene: A Library for Understanding and Improving PyTorch Models via Interventions (NAACL 2024)

When to Use pyvene

Use pyvene when you need to:

  • Perform causal tracing (ROME-style localization)
  • Run activation patching experiments
  • Conduct interchange intervention training (IIT)
  • Test causal hypotheses about model components
  • Share/reproduce intervention experiments via HuggingFace
  • Work with any PyTorch architecture (not just transformers)

Consider alternatives when:

  • You need exploratory activation analysis → Use TransformerLens
  • You want to train/analyze SAEs → Use SAELens
  • You need remote execution on massive models → Use nnsight
  • You want lower-level control → Use nnsight

Installation

pip install pyvene

Workflow 1: Causal Tracing (ROME-style)

Locate where factual associations are stored by corrupting inputs and restoring activations.

Step-by-Step
import pyvene as pv
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained("gpt2-xl")
tokenizer = AutoTokenizer.from_pretrained("gpt2-xl")

# 1. Define clean and corrupted inputs
clean_prompt = "The Space Needle is in downtown"
corrupted_prompt = "The ##### ###### ## ## ########"  # Noise

clean_tokens = tokenizer(clean_prompt, return_tensors="pt")
corrupted_tokens = tokenizer(corrupted_prompt, return_tensors="pt")

# 2. Get clean activations (source)
with torch.no_grad():
    clean_outputs = model(**clean_tokens, output_hidden_states=True)
    clean_states = clean_outputs.hidden_states

# 3. Define restoration intervention
def run_causal_trace(layer, position):
    """Restore clean activation at specific layer and position."""
    config = pv.IntervenableConfig(
        representations=[
            pv.RepresentationConfig(
                layer=layer,
                component="block_output",
                intervention_type=pv.VanillaIntervention,
                unit="pos",
                max_number_of_units=1,
            )
        ]
    )

    intervenable = pv.IntervenableModel(config, model)

    # Run with intervention
    _, patched_outputs = intervenable(
        base=corrupted_tokens,
        sources=[clean_tokens],
        unit_locations={"sources->base": ([[[position]]], [[[position]]])},
        output_original_output=True,
    )

    # Return probability of correct token
    probs = torch.softmax(patched_outputs.logits[0, -1], dim=-1)
    seattle_token = tokenizer.encode(" Seattle")[0]
    return probs[seattle_token].item()

# 4. Sweep over layers and positions
n_layers = model.config.n_layer
seq_len = clean_tokens["input_ids"].shape[1]

results = torch.zeros(n_layers, seq_len)
for layer in range(n_layers):
    for pos in range(seq_len):
        results[layer, pos] = run_causal_trace(layer, pos)

# 5. Visualize (layer x position heatmap)
# High values indicate causal importance
Checklist
  • Prepare clean prompt with target factual association
  • Create corrupted version (noise or counterfactual)
  • Define intervention config for each (layer, position)
  • Run patching sweep
  • Identify causal hotspots in heatmap

Workflow 2: Activation Patching for Circuit Analysis

Test which components are necessary for a specific behavior.

Step-by-Step
import pyvene as pv
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model = AutoModelForCausalLM.from_pretrained("gpt2")
tokenizer = AutoTokenizer.from_pretrained("gpt2")

# IOI task setup
clean_prompt = "When John and Mary went to the store, Mary gave a bottle to"
corrupted_prompt = "When John and Mary went to the store, John gave a bottle to"

clean_tokens = tokenizer(clean_prompt, return_tensors="pt")
corrupted_tokens = tokenizer(corrupted_prompt, return_tensors="pt")

john_token = tokenizer.encode(" John")[0]
mary_token = tokenizer.encode(" Mary")[0]

def logit_diff(logits):
    """IO - S logit difference."""
    return logits[0, -1, john_token] - logits[0, -1, mary_token]

# Patch attention output at each layer
def patch_attention(layer):
    config = pv.IntervenableConfig(
        representations=[
            pv.RepresentationConfig(
                layer=layer,
                component="attention_output",
                intervention_type=pv.VanillaIntervention,
            )
        ]
    )

    intervenable = pv.IntervenableModel(config, model)

    _, patched_outputs = intervenable(
        base=corrupted_tokens,
        sources=[clean_tokens],
    )

    return logit_diff(patched_outputs.logits).item()

# Find which layers matter
results = []
for layer in range(model.config.n_layer):
    diff = patch_attention(layer)
    results.append(diff)
    print(f"Layer {layer}: logit diff = {diff:.3f}")

Workflow 3: Interchange Intervention Training (IIT)

Train interventions to discover causal structure.

Step-by-Step
import pyvene as pv
from transformers import AutoModelForCausalLM
import torch

model = AutoModelForCausalLM.from_pretrained("gpt2")

# 1. Define trainable intervention
config = pv.IntervenableConfig(
    representations=[
        pv.RepresentationConfig(
            layer=6,
            component="block_output",
            intervention_type=pv.RotatedSpaceIntervention,  # Trainable
            low_rank_dimension=64,  # Learn 64-dim subspace
        )
    ]
)

intervenable = pv.IntervenableModel(config, model)

# 2. Set up training
optimizer = torch.optim.Adam(
    intervenable.get_trainable_parameters(),
    lr=1e-4
)

# 3. Training loop (simplified)
for base_input, source_input, target_output in dataloader:
    optimizer.zero_grad()

    _, outputs = intervenable(
        base=base_input,
        sources=[source_input],
    )

    loss = criterion(outputs.logits, target_output)
    loss.backward()
    optimizer.step()

# 4. Analyze learned intervention
# The rotation matrix reveals causal subspace
rotation = intervenable.interventions["layer.6.block_output"][0].rotate_layer

# Low-rank rotation finds interpretable subspaces
config = pv.IntervenableConfig(
    representations=[
        pv.RepresentationConfig(
            layer=8,
            component="block_output",
            intervention_type=pv.LowRankRotatedSpaceIntervention,
            low_rank_dimension=1,  # Find 1D causal direction
        )
    ]
)

Workflow 4: Model Steering (Honest LLaMA)

Steer model behavior during generation.

import pyvene as pv
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-2-7b-hf")
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-2-7b-hf")

# Load pre-trained steering intervention
intervenable = pv.IntervenableModel.load(
    "zhengxuanzenwu/intervenable_honest_llama2_chat_7B",
    model=model,
)

# Generate with steering
prompt = "Is the earth flat?"
inputs = tokenizer(prompt, return_tensors="pt")

# Intervention applied during generation
outputs = intervenable.generate(
    inputs,
    max_new_tokens=100,
    do_sample=False,
)

print(tokenizer.decode(outputs[0]))

Saving and Sharing Interventions

# Save locally
intervenable.save("./my_intervention")

# Load from local
intervenable = pv.IntervenableModel.load(
    "./my_intervention",
    model=model,
)

# Share on HuggingFace
intervenable.save_intervention("username/my-intervention")

# Load from HuggingFace
intervenable = pv.IntervenableModel.load(
    "username/my-intervention",
    model=model,
)

Common Issues & Solutions

Issue: Wrong intervention location
# WRONG: Incorrect component name
config = pv.RepresentationConfig(
    component="mlp",  # Not valid!
)

# RIGHT: Use exact component name
config = pv.RepresentationConfig(
    component="mlp_output",  # Valid
)
Issue: Dimension mismatch
# Ensure source and base have compatible shapes
# For position-specific interventions:
config = pv.RepresentationConfig(
    unit="pos",
    max_number_of_units=1,  # Intervene on single position
)

# Specify locations explicitly
intervenable(
    base=base_tokens,
    sources=[source_tokens],
    unit_locations={"sources->base": ([[[5]]], [[[5]]])},  # Position 5
)
Issue: Memory with large models
# Use gradient checkpointing
model.gradient_checkpointing_enable()

# Or intervene on fewer components
config = pv.IntervenableConfig(
    representations=[
        pv.RepresentationConfig(
            layer=8,  # Single layer instead of all
            component="block_output",
        )
    ]
)
Issue: LoRA integration
# pyvene v0.1.8+ supports LoRAs as interventions
config = pv.RepresentationConfig(
    intervention_type=pv.LoRAIntervention,
    low_rank_dimension=16,
)

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

  1. 1Read the source. Confirm the input, expected output, dependencies and permissions.
  2. 2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
  3. 3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
