Question

我正在关注ULMFiT的example。这是github。

我正在Google Colab中运行model_forward_pass.ipynb。我正在运行第一个代码块：

import pandas as pd
import numpy as np
import torch
!pip install fastai==0.7.0
!pip install torch
import fastai
from fastai.imports import *
from fastai.torch_imports import *
from fastai.core import *
from fastai.model import fit
from fastai.dataset import *

import torchtext
from torchtext import vocab, data
from torchtext.datasets import language_modeling

from fastai.rnn_reg import *
from fastai.rnn_train import *
from fastai.nlp import *
from fastai.lm_rnn import *
from fastai.text import *

import dill as pickle
!pip install spacy
!python -m spacy download en
import spacy
import html

import pickle
import collections
#!pip install nbimporter
import nbimporter

我遇到以下错误：

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-bd3be060f151> in <module>()

      7 from fastai.imports import *
----> 8 from fastai.torch_imports import *
      9 from fastai.core import *
     10 from fastai.model import fit

ModuleNotFoundError: No module named 'torch.utils.checkpoint'

我找到了类似的问题here，但是我仍然不确定如何解决问题。我该怎么做才能解决此问题？

问题导入模块：ModuleNotFoundError：没有名为“ torch.utils.checkpoint”的模块
