问题描述
我需要将 .pdf 文件转换为 .jpeg 文件才能对文本进行 OCR。 我找到了这个代码：
from pdf2image import convert_from_path
pages = convert_from_path('img732.pdf',500)
for page in pages:
page.save('out.jpg','JPEG')
我收到了这个错误：
Traceback (most recent call last):
File "C:\Users\david\AppData\Local\Programs\Python\python39\lib\site-package\pdf2image\pdf2image.py",line 441,in pdfinfo_from_path

During handling of the above exception,another exception occurred:

我在 .py 文件的同一目录中有 .pdf 文件。问题出在哪里？
解决方法
我猜这个问题是特定于库的。但是，您可以使用此解决方案成功运行。
- 下载适用于 windows 的 poppler 工具（我推荐最新版本）：
http://blog.alivate.com.au/poppler-windows/ - 下载后解压到poppler文件夹任意路径
- 添加环境变量 poppler 的
"bin"文件夹： - 并重新启动您的 Python 工作区
