# 统计模型计算量和参数量
1. 定义模型
```python
import torch.nn.functional as F
import torchvision
from mmengine.model import BaseModel
class MMResNet50(BaseModel):
def __init__(self):
super().__init__()
self.resnet = torchvision.models.resnet50()
def forward(self, imgs, labels=None, mode='tensor'):
x = self.resnet(imgs)
if mode == 'loss':
return {'loss': F.cross_entropy(x, labels)}
elif mode == 'predict':
return x, labels
elif mode == 'tensor':
return x
```
2. 统计计算量和参数量
```python
from mmengine.analysis import get_model_complexity_info
input_shape = (3, 224, 224)
model = MMResNet50()
analysis_results = get_model_complexity_info(model, input_shape)
```
- 以表格的形式显示
```python
print(analysis_results['out_table'])
```
