    torch.nn.Linear(1024, 2048),
    torch.nn.ReLU(),
    torch.nn.Linear(2048, 2048),

input_data = torch.randn(1, 1024)

# 预热
for _ in range(100):
    with torch.no_grad():
        _ = model(input_data)

start_time = time.time()
for _ in range(iterations):
    with torch.no_grad():
        output = model(input_data)
end_time = time.time()

latency = (end_time - start_time) / iterations * 1000
throughput = iterations / (end_time - start_time)

print(f"平均延迟: {latency:.3f} ms")
print(f"吞吐量: {throughput:.2f} samples/s")

# 创建训练模型
class ConvNet(nn.Module):
    def __init__(self):
        super(ConvNet, self).__init__()
        self.conv1 = nn.Conv2d(3, 64, 3, padding=1)
        self.conv2 = nn.Conv2d(64, 128, 3, padding=1)
        self.conv3 = nn.Conv2d(128, 256, 3, padding=1)
        self.fc = nn.Linear(256 * 4 * 4, 10)
        self.pool = nn.MaxPool2d(2, 2)
        self.relu = nn.ReLU()
    
    def forward(self, x):
        x = self.pool(self.relu(self.conv1(x)))
        x = self.pool(self.relu(self.conv2(x)))
        x = self.pool(self.relu(self.conv3(x)))
        x = x.view(-1, 256 * 4 * 4)
        x = self.fc(x)
        return x

# 训练性能测试
batch_size = 128
input_data = torch.randn(batch_size, 3, 32, 32).to(device)
labels = torch.randint(0, 10, (batch_size,)).to(device)

# 预热
for _ in range(10):
    optimizer.zero_grad()
    outputs = model(input_data)
    loss = criterion(outputs, labels)
    loss.backward()
    optimizer.step()

# 性能测试
iterations = 1000
start_time = time.time()
for _ in range(iterations):
    optimizer.zero_grad()
    outputs = model(input_data)
    loss = criterion(outputs, labels)
    loss.backward()
    optimizer.step()
torch.cuda.synchronize()
end_time = time.time()

samples_per_sec = (iterations * batch_size) / (end_time - start_time)
print(f"训练吞吐量: {samples_per_sec:.2f} samples/s")

start_time = time.time()
for _ in range(iterations):
    optimizer.zero_grad()
    with autocast():
        outputs = model(input_data)
        loss = criterion(outputs, labels)
    scaler.scale(loss).backward()
    scaler.step(optimizer)
    scaler.update()
torch.cuda.synchronize()
end_time = time.time()

print(f"性能提升: {mixed_samples_per_sec / samples_per_sec:.2f}x")

五、分布式训练性能测试

5.1 多GPU数据并行

import torch.distributed as dist

from torch.nn.parallel import DistributedDataParallel as DDP

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)
    labels = torch.randint(0, 10, (batch_size,)).to(rank)
    
    # 性能测试
    iterations = 1000
    start_time = time.time()
    for _ in range(iterations):
        optimizer.zero_grad()
        outputs = ddp_model(input_data)
        loss = criterion(outputs, labels)
        loss.backward()
        optimizer.step()
    
    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)

分布式训练性能：

GPU数量	批次大小	吞吐量	扩展效率	通信开销
1	128	2100 img/s	100%	0%
2	256	3950 img/s	94%	6%

for _ in range(iterations):
    outputs = ort_session.run(None, {'input': input_data})
end_time = time.time()

onnx_latency = (end_time - start_time) / iterations * 1000
print(f"ONNX推理延迟: {onnx_latency:.3f} ms")

6.2 TorchScript优化

# TorchScript编译

        self.size = size
    
    def __len__(self):
        return self.size
    
    def __getitem__(self, idx):
        return torch.randn(3, 224, 224), torch.randint(0, 1000, (1,))

# 测试不同worker数量的数据加载性能
dataset = DummyDataset(10000)

for num_workers in [0, 2, 4, 8, 16]:
    dataloader = data.DataLoader(dataset, batch_size=128, 
                                 num_workers=num_workers, pin_memory=True)
    
    start_time = time.time()
    for batch_idx, (images, labels) in enumerate(dataloader):
        if batch_idx >= 100:
            break
    end_time = time.time()
    
    throughput = 100 * 128 / (end_time - start_time)
    print(f"Workers={num_workers}: {throughput:.2f} samples/s")

7.2 模型编译优化
