MindSpore是一个开源的深度学习框架，可以用来构建、训练和部署深度学习模型。在MindSpore中，可以使用`ResNet`类实现ResNet101模型。

下面是一个示例代码，展示了如何使用MindSpore实现ResNet101模型，并使用ImageNet数据集进行训练和推理：

\`\`\`python import mindspore import mindspore.nn as nn import mindspore.common.dtype as mstype

## 定义ResNet101模型 ##

def construct(self, x):
        x = self.conv1(x)
        x = self.bn1(x)
        x = self.relu(x)
        x = self.maxpool(x)
        x = self.layer1(x)
        x = self.layer2(x)
        x = self.layer3(x)
        x = self.layer4(x)
        x = self.avgpool(x)
        x = self.flatten(x)
        x = self.fc(x)
        return x

## 定义ResNet101的Bottleneck块 ##
