Running Norbert: CUDA and Device Selection

Automatic Device Detection

Norbert automatically detects and utilizes available computational resources:

import torch
from norbert.core.model import NorbertBaseModel

# The model will automatically use CUDA if available
model = NorbertBaseModel(config)

# Verify the device being used
print(f"Model is running on: {next(model.parameters()).device}")

Explicit Device Selection

You can explicitly control device selection:

# Force CPU usage
model = NorbertBaseModel(config, device='cpu')

# Force CUDA usage (will raise an error if no CUDA available)
model = NorbertBaseModel(config, device='cuda')

# Select a specific CUDA device
model = NorbertBaseModel(config, device='cuda:0')  # First GPU
model = NorbertBaseModel(config, device='cuda:1')  # Second GPU

System Requirements

  • Without CUDA: Any system with Python 3.13.2+
  • With CUDA:
    • NVIDIA GPU with CUDA support
    • CUDA Toolkit 11.x or 12.x
    • Compatible NVIDIA GPU driver

Performance Tips

  • For multi-GPU systems, use torch.nn.DataParallel or torch.nn.parallel.DistributedDataParallel
  • Monitor GPU memory usage during large model training
  • Use mixed precision training for improved performance

Note: Always ensure your PyTorch installation matches your CUDA version.

Test Verification Script

import torch
from norbert.core.model import NorbertBaseModel, NorbertConfig
from norbert.modules.training import NorbertTrainer

# Configuration
config = NorbertConfig.from_pretrained('base')
model = NorbertBaseModel(config)

# Multimodal Inputs
inputs = {
    'text': torch.randn(32, 512, 768),      # Text embedding
    'image': torch.randn(32, 3, 224, 224),  # Image tensor
    'equation': torch.randn(32, 100),       # Equation representation
    'code': torch.randn(32, 512, 768)       # Code embedding
}

# Simulate Labels
labels = torch.randint(0, 10, (32,))

# Training
trainer = NorbertTrainer(model, config)
loss = trainer.training_step((inputs, labels), batch_idx=0)

# Inference
output = model(inputs)
