python - 导入错误 : cannot import name 'AutoModelWithLMHead' from 'transformers'

Question

这实际上是我试图运行的所有代码:

from transformers import AutoModelWithLMHead, AutoTokenizer
import torch

tokenizer = AutoTokenizer.from_pretrained("microsoft/DialoGPT-small")
model = AutoModelWithLMHead.from_pretrained("microsoft/DialoGPT-small")

我收到此错误:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-14-aad2e7a08a74> in <module>
----> 1 from transformers import AutoModelWithLMHead, AutoTokenizer
      2 import torch
      3 
      4 tokenizer = AutoTokenizer.from_pretrained("microsoft/DialoGPT-small")
      5 model = AutoModelWithLMHead.from_pretrained("microsoft/DialoGPT-small")

ImportError: cannot import name 'AutoModelWithLMHead' from 'transformers' (c:\python38\lib\site-packages\transformers\__init__.py)

我该怎么办？

Answer 1

我解决了!显然 AutoModelWithLMHead 在我的版本中被删除了。
现在你需要使用 AutoModelForCausalLM对于因果语言模型，AutoModelForMaskedLM用于屏蔽语言模型和 AutoModelForSeq2SeqLM用于编码器-解码器模型。
所以在我的情况下，代码如下所示:

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

tokenizer = AutoTokenizer.from_pretrained("microsoft/DialoGPT-small")
model = AutoModelForCausalLM.from_pretrained("microsoft/DialoGPT-small")
