（1）参考这篇博客，里面有这节课的图片下载代码

folder = 'teddys'
file = 'urls_teddys.txt'
path = Path('data/bears')
dest = path/folder
dest.mkdir(parents=True, exist_ok=True)

download_images(path/file, dest, max_pics=200)

# 如果下载出现问题，uncomment下列代码查看
# download_images(path/file, dest, max_pics=20, max_workers=0)

（2）去fastai源代码里找image_download的定义
（3）fastai官网类似帖子
来自fastai中文笔记
Step 4: Saving your data files
如果你希望改写你的文件，你需要允许你的Colaboratory instance读取和改写你的 Google Drive. 你只需要在每一个notebook的第一个Cell中写入以下代码

from google.colab import drive
drive.mount('/content/gdrive', force_remount=True)
root_dir = "/content/gdrive/My Drive/"
base_dir = root_dir + 'fastai-v3/'

现在，Google Drive 变成了一个文件系统允许标准python读写文件. 不要忘记给所有notebook的根目录地址前加上 base_dir . 例如, 在 lesson2-download.ipynb 5th cell, 做一下修改

path = Path(base_dir + 'data/bears')
dest = path/folder
dest.mkdir(parents=True, exist_ok=True)

不一定管用，上面是从drive里读数据，好像跟你的不一样，必要的话，把那你的代码贴出来
