当我尝试将 pdf 转换为 jpeg 时出现多个错误

Question

我需要将 .pdf 文件转换为 .jpeg 文件以对文本进行 OCR。我找到这段代码：

from pdf2image import convert_from_path
pages = convert_from_path('img732.pdf', 500)
for page in pages:
  page.save('out.jpg', 'JPEG')

我得到了这个错误：

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

FileNotFoundError: [WinError 2] Impossibile trovare il file specificato

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？

Answer 1

我想这个问题是图书馆特有的。但是，您可以成功地将此解决方案用于运行。

下载 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
