M09*_*009 8 model machine-learning resnet pytorch fast-ai
所以我试图使用以下方式加载模型:
learn = create_cnn(data, models.resnet50, lin_ftrs=[2048], metrics=accuracy)
learn.clip_grad();
learn.load(f'{name}-stage-2.1')

但我收到以下错误
RuntimeError: Error(s) in loading state_dict for Sequential:
size mismatch for 1.8.weight: copying a param with shape torch.Size([5004, 2048]) from checkpoint, the shape in current model is torch.Size([4542, 2048]).
size mismatch for 1.8.bias: copying a param with shape torch.Size([5004]) from checkpoint, the shape in current model is torch.Size([4542]).

唯一不同的是,我添加了stage-2.1模型中不存在的随机验证拆分,当我删除该拆分并且没有经过验证的集时,因为stage-2.1经过训练的一切进展顺利。
发生了什么?
