为什么我的Python代码在Jupyter Notebook中工作，而不是作为脚本？

Question

I'm trying to open up a PDF as an image using Wand. If I run the code below in Jupyter Notebook, it works fine. If I run the code as a script from Command Prompt, I get an error message. For some reason, the module won't load when it's run outside of Jupyter Notebook. Does anyone have any suggestions?

Windows

Python 3.7.2 (64 bit)

from wand.image import Image

with Image(filename="C:/test.pdf", resolution=300) as img:
    print(type(img))

This is the error message:

Traceback (most recent call last):
  File "C:\Untitled.py", line 7, in <module>
    from wand.image import Image
  File "C:\Users\spencer.rand\AppData\Local\Programs\Python\Python37\lib\site-packages\wand\image.py", line 18, in <module>
    from . import compat

AttributeError: module 'collections' has no attribute 'abc'

Looks like there's an issue with wand and collections that was fixed 2 weeks ago: https://github.com/emcconville/wand/pull/398

Try updating your wand install: pip install --upgrade wand
