def train_ddp(rank, world_size):
    # 初始化进程组
    dist.init_process_group("nccl", rank=rank, world_size=world_size)
    
    # 创建模型
    model = ConvNet().to(rank)
    ddp_model = DDP(model, device_ids=[rank])
    
    # 训练
    criterion = nn.CrossEntropyLoss()
    optimizer = torch.optim.Adam(ddp_model.parameters(), lr=0.001)
    
    batch_size = 128
    input_data = torch.randn(batch_size, 3, 32, 32).to(rank)

    if rank == 0:
        end_time = time.time()
        total_samples = iterations * batch_size * world_size
        throughput = total_samples / (end_time - start_time)
        print(f"分布式训练吞吐量: {throughput:.2f} samples/s")
    
    dist.destroy_process_group()

# 启动分布式训练
world_size = 4  # 4个GPU
mp.spawn(train_ddp, args=(world_size,), nprocs=world_size, join=True)

# 导出ONNX模型
dummy_input = torch.randn(1, 1024)
torch.onnx.export(model, dummy_input, "model.onnx", 
                  input_names=['input'], output_names=['output'],
                  dynamic_axes={'input': {0: 'batch_size'}, 'output': {0: 'batch_size'}})

# ONNX Runtime推理
ort_session = ort.InferenceSession("model.onnx")

# 性能测试
