Question

实际上，我正在尝试将pdf文件标记为一个句子，首先我使用pypdf2，但面临数据丢失和格式不正确的问题。所以我尝试了ocr，但是将pdf转换为图像时却遇到了poppler问题谁能帮我解决这个问题

pages = convert_from_path(PDF_file, 600)

FileNotFoundError                         Traceback (most recent call last)
~\Anaconda3\lib\site-packages\pdf2image\pdf2image.py in _page_count(pdf_path, userpw, poppler_path)
    239             env["LD_LIBRARY_PATH"] = poppler_path + ":" + env.get("LD_LIBRARY_PATH", "")
--> 240         proc = Popen(command, env=env, stdout=PIPE, stderr=PIPE)
    241

    774                                 errread, errwrite,

    776         except:

-> 1178                                          startupinfo)
   1179             finally:

FileNotFoundError: [WinError 2] The system cannot find the file specified

在处理上述异常期间，发生了另一个异常：

    243     except:

    245 
    246     try:

PDFInfoNotInstalledError: Unable to get page count.

poppler是否已安装并位于PATH中？

Answer 1

当我在Anaconda提示符下安装以下代码时，我的代码工作正常，请检查它是否也对您有用！

conda install -c conda-forge poppler

Answer 2

如果下载poppler，这非常容易。 https://github.com/oschwartz10612/poppler-windows/releases/ 解压缩并移入程序文件后最后将环境变量设置为poppler bin文件夹。 [系统>高级系统设置>环境变量>将poppler bin作为新项添加到Path中] 说明文件： https://pypi.org/project/pdf2image/

PDFInfoNotInstalledError：无法获取页数。 poppler是否已安装且位于PATH中？
