Error: 'DenseNet' object has no attribute 'logits'

I used the pretrainedmodels.densent121 to trian my own dataset, but when I load the model I trianed, I get the error: 'DenseNet' object has no attribute 'logits', I wnant to know why? import pretrainedmodels model_daibao = torch.load('densenet121_daibao_model_1') `AttributeError Traceback (most recent call last) in () 1 import pretrainedmodels ----> 2 model_daibao = torch.load('densenet121_daibao_model_1') 3 model_kouzhao = torch.load('densenet121_kouzhao_model_2') 4 model_yanjing = torch.load('densenet121_yanjing_model_2') 5 model_maozi = torch.load('densenet_maozi_model_1')

I have the same problem with Resnet just like you, but I don't know how to solve this problem.

Hi,

You should save your model using the state dictionary: https://pytorch.org/tutorials/beginner/saving_loading_models.html
