ImportError：无法导入名称“download_url_to_file”

Question

我尝试在 torch hub 中运行一个使用 download_url_to_file 方法的 Python 脚本，但出现以下错误：

Traceback (most recent call last):
  File "crop-video.py", line 1, in <module>
    import face_alignment
  File "$PROGRAMS_PATH$\Python\Python36\lib\site-packages\face_alignment-1.3.3-py3.6.egg\face_alignment\__init__.py", line 7, in <module>
  File "$PROGRAMS_PATH$\Python\Python36\lib\site-packages\face_alignment-1.3.3-py3.6.egg\face_alignment\api.py", line 7, in <module>
  File "$PROGRAMS_PATH$\Python\Python36\lib\site-packages\face_alignment-1.3.3-py3.6.egg\face_alignment\utils.py", line 13, in <module>
ImportError: cannot import name 'download_url_to_file'

在集线器文件中似乎没有找到download_url_to_file方法，但我检查了torch hub，并确保它已定义！如何修复此错误？
