# Load model configuration  
config_path = "Qybera/LisaV3.0/config.json"
with open(config_path, 'r') as f:
    config = json.load(f)

# Import and create model (requires lisa_model.py)
from lisa_model import create_lisa_model

# Create and load model
model, device = create_lisa_model(model_config)

# Load trained weights
state_dict = torch.load("Qybera/LisaV3.0/pytorch_model.bin", map_location=device)
model.load_state_dict(state_dict)
model.eval()

# Prepare inputs (must be exactly sequence length 30)
vision_input = torch.randn(1, 30, 5, 224, 224).to(device)  # 5-channel multispectral
audio_input = torch.randn(1, 30, 1, 80, 200).to(device)    # Mel spectrograms

# Generate comprehensive analysis
with torch.no_grad():
    output = model(vision_input, audio_input)

# Access different analysis components
vision_features = output['vision_analysis']['features']  # [1, 30, 512]
audio_emotions = output['audio_analysis']['emotion']     # [1, 30, 7]
reasoning_output = output['reasoning']                   # [1, 30, 1024]

print(f"Vision features: {vision_features.shape}")

# Process multiple sequences
batch_size = 2
vision_batch = torch.randn(batch_size, 30, 5, 224, 224).to(device)
audio_batch = torch.randn(batch_size, 30, 1, 80, 200).to(device)

Individual Component Access

# Access individual model components
vision_encoder = model.vision_encoder
audio_encoder = model.audio_encoder
reasoning_module = model.reasoning_module

# Use vision encoder separately
vision_analysis = vision_encoder(vision_input)
print("Vision analysis keys:", list(vision_analysis.keys()))

# Use audio encoder separately  
audio_analysis = audio_encoder(audio_input)
print("Audio analysis keys:", list(audio_analysis.keys()))

Input Requirements

⚠️ Important: The model expects exactly 30 frames/steps per sequence due to memory constraints.

• Vision Input: [batch_size, 30, 5, 224, 224] - 5-channel multispectral images
• Audio Input: [batch_size, 30, 1, 80, 200] - Mel spectrograms with 80 frequency bins
• Batch Size: Flexible (tested up to batch_size=2)
• Sequence Length: Fixed at 30 (longer sequences will cause errors)

Training Information

• Framework: PyTorch
• Final Training Loss: 0.611
• Final Validation Loss: 0.639
• Training Epochs: 50
• Learning Rate: 2.14e-05 (with scheduling)
• Optimizer: AdamW
• Dataset: YouTube videos with multimodal processing

Limitations

• Fixed Sequence Length: Must use exactly 30 frames per sequence
• Memory Constraints: Cannot handle variable sequence lengths due to conversation memory implementation
• CPU Performance: ~17s per inference on CPU (GPU recommended for real-time use)
• Input Format: Requires specific multispectral (5-channel) vision input

Applications

• Multimodal Scene Analysis: Comprehensive understanding of visual scenes with audio context
• Emotion Recognition: Real-time emotion detection from audio input
• Content Analysis: Understanding of both visual and audio content
• Spatial Reasoning: 3D spatial understanding and object detection
• Interactive AI: Conversation memory enables contextual interactions
