为什么我的 Python 代码可以在 Jupyter Notebook 中运行,但不能作为脚本运行?
Why does my Python code work in Jupyter Notebook but not as a script?
我正在尝试使用 Wand 打开 PDF 作为图像。如果我在 Jupyter Notebook 中 运行 下面的代码,它工作正常。如果我 运行 命令提示符中的代码作为脚本,我会收到一条错误消息。出于某种原因,模块在 Jupyter Notebook 之外 运行 时不会加载。有没有人有什么建议?
Windows
Python 3.7.2(64 位)
from wand.image import Image
with Image(filename="C:/test.pdf", resolution=300) as img:
print(type(img))
这是错误信息:
Traceback (most recent call last):

魔杖和 collections 似乎有问题,已于 2 周前修复:https://github.com/emcconville/wand/pull/398
尝试更新您的魔杖安装:pip install --upgrade wand
