• Progressive Growing from 8x8 to 128x128
• Minibatch Discrimination to prevent mode collapse
• Instance Noise for training stability
• Dynamic batch sizing based on resolution

Usage

import torch
from torch import nn

# Define generator architecture
class Generator(nn.Module):
    # ... (architecture code)

# Load the model
generator = Generator(latent_dim=100, channels=3)
generator.load_state_dict(torch.load('model/generator_epoch_8000.pt'))
generator.eval()

# Generate images
z = torch.randn(1, 100)
with torch.no_grad():
    fake_image = generator(z)
    # Convert to range [0, 1] for display
    fake_image = (fake_image + 1) / 2.0
