neural-dsl 0.2.5

A domain-specific language and debugger for neural networks

⚠️ WARNING: Neural-dsl is a WIP DSL and debugger—bugs exist, feedback welcome! This project is under active development and not yet production-ready!

Neural: A Neural Network Programming Language

Pain Points Solved

Neural addresses deep learning challenges across Criticality (how essential) and Impact Scope (how transformative):

Criticality / Impact	Low Impact	Medium Impact	High Impact
High			- Shape Mismatches: Pre-runtime validation stops runtime errors. - Debugging Complexity: Real-time tracing & anomaly detection.
Medium		- Steep Learning Curve: No-code GUI eases onboarding.	- Framework Switching: One-flag backend swaps. - HPO Inconsistency: Unified tuning across frameworks.
Low	- Boilerplate: Clean DSL syntax saves time.	- Model Insight: FLOPs & diagrams. - Config Fragmentation: Centralized setup.

Why It Matters

• Core Value: Fix critical blockers like shape errors and debugging woes with game-changing tools.
• Strategic Edge: Streamline framework switches and HPO for big wins.
• User-Friendly: Lower barriers and enhance workflows with practical features.

Neural is a domain-specific language (DSL) designed for defining, training, debugging, and deploying neural networks whether via code, CLI, or a no-code interface. With declarative syntax, cross-framework support, and built-in execution tracing (NeuralDbg), it simplifies deep learning development.

NeuralDbg: Built-in Neural Network Debugger

NeuralDbg provides real-time execution tracing, profiling, and debugging, allowing you to visualize and analyze deep learning models in action.

✅ Real-Time Execution Monitoring – Track activations, gradients, memory usage, and FLOPs.

✅ Shape Propagation Debugging – Visualize tensor transformations at each layer. ✅ Gradient Flow Analysis – Detect vanishing & exploding gradients. ✅ Dead Neuron Detection – Identify inactive neurons in deep networks. ✅ Anomaly Detection – Spot NaNs, extreme activations, and weight explosions. ✅ Step Debugging Mode – Pause execution and inspect tensors manually.

Installation

Clone the repository

git clone https://github.com/yourusername/neural.git cd neural

Create a virtual environment (recommended)

python -m venv venv source venv/bin/activate # Linux/macOS venv\Scripts\activate # Windows

Install dependencies

pip install -r requirements.txt

pip install neural-dsl

see v0.2.5 for latest HPO optimizer fixes and improvements

Prerequisites: Python 3.8+, pip

Quick Start

1. Define a Model

Create mnist.neural:

network MNISTClassifier {
  input: (28, 28, 1)  # Channels-last format
  layers:
    Conv2D(filters=32, kernel_size=(3,3), activation="relu")
    MaxPooling2D(pool_size=(2,2))
    Flatten()
    Dense(units=128, activation="relu")
    Dropout(rate=0.5)
    Output(units=10, activation="softmax")

  loss: "sparse_categorical_crossentropy"
  optimizer: Adam(learning_rate=0.001)
  metrics: ["accuracy"]

  train {
    epochs: 15
    batch_size: 64
    validation_split: 0.2
  }
}

3. Run Or Compile The Model

neural run mnist.neural --backend tensorflow --output mnist_tf.py
# Or for PyTorch:
neural run mnist.neural --backend pytorch --output mnist_torch.py

4. Visualize Architecture

neural visualize mnist.neural --format png

This will create architecture.png, shape_propagation.html, and tensor_flow.html for inspecting the network structure and shape propagation.

5. Debug with NeuralDbg

neural debug mnist.neural

Open your browser to http://localhost:8050 to monitor execution traces, gradients, and anomalies interactively.

6. Use The No-Code Interface

neural --no_code

Open your browser to http://localhost:8051 to build and compile models via a graphical interface.

🛠 Debugging with NeuralDbg

🔹 1️⃣ Start Real-Time Execution Tracing

python neural.py debug mnist.neural

Features: ✅ Layer-wise execution trace ✅ Memory & FLOP profiling ✅ Live performance monitoring

🔹 2️⃣ Analyze Gradient Flow

python neural.py debug --gradients mnist.neural

Detect vanishing/exploding gradients with interactive charts.

🔹 3️⃣ Identify Dead Neurons

python neural.py debug --dead-neurons mnist.neural

🛠 Find layers with inactive neurons (common in ReLU networks).

🔹 4️⃣ Detect Training Anomalies

python neural.py debug --anomalies mnist.neural

Flag NaNs, weight explosions, and extreme activations.

🔹 5️⃣ Step Debugging (Interactive Tensor Inspection)

python neural.py debug --step mnist.neural

🔍 Pause execution at any layer and inspect tensors manually.
