AttributeError: ‘_IncompatibleKeys‘ object has no attribute ‘eval‘

pytorch读取权重文件后出现

   File "test.py", line 61, in main
    resNet50.eval()
AttributeError: '_IncompatibleKeys' object has no attribute 'eval'

• 代码

#保存的权重文件
resNet50 = resnet.resnet50()
resNet50 =  resNet50.load_state_dict(torch.load(resNet_path)['state_dict'])
resNet50.eval()

• 修改
  这里的模型不能用“=”来赋值，第一行代码导入模型的结构文件，下面应该直接在此模型上调用load_state_dict函数加载权重文件

#保存的权重文件
resNet50 = resnet.resnet50()
resNet50.load_state_dict(torch.load(resNet_path)['state_dict'])
resNet50.eval()
