python-3.x - pdf2image 路径中的 Poppler

Question

我正在尝试使用 pdf2image，看来我需要一个名为 propeller 的东西:

(sum_env) C:\Users\antoi\Documents\Programming\projects\summarizer>python ocr.py -i fr13_idf.pdf
Traceback (most recent call last):
  File "c:\Users\antoi\Documents\Programming\projects\summarizer\sum_env\lib\site-packages\pdf2image\pdf2image.py", line 165, in __page_count
    proc = Popen(["pdfinfo", pdf_path], stdout=PIPE, stderr=PIPE)
  File "C:\Python37\lib\subprocess.py", line 769, in __init__
    restore_signals, start_new_session)
  File "C:\Python37\lib\subprocess.py", line 1172, in _execute_child
    startupinfo)
FileNotFoundError: [WinError 2] The system cannot find the file specified

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "ocr.py", line 53, in <module>
    pdfspliterimager(image_path)
  File "ocr.py", line 32, in pdfspliterimager
    pages = convert_from_path("document-page%s.pdf" % i, 500)
  File "c:\Users\antoi\Documents\Programming\projects\summarizer\sum_env\lib\site-packages\pdf2image\pdf2image.py", line 30, in convert_from_path
    page_count = __page_count(pdf_path, userpw)
  File "c:\Users\antoi\Documents\Programming\projects\summarizer\sum_env\lib\site-packages\pdf2image\pdf2image.py", line 169, in __page_count
    raise Exception('Unable to get page count. Is poppler installed and in PATH?')
Exception: Unable to get page count. Is poppler installed and in PATH?

我试过 this link但它下载的东西并没有解决我的问题。

Answer 1

第一个下载波普勒 从这里 here ,然后解压。在代码部分添加 poppler_path=r'C:\Program Files\poppler-0.68.0\bin' (例如)如下

from pdf2image import convert_from_path
images = convert_from_path("mypdf.pdf", 500,poppler_path=r'C:\Program Files\poppler-0.68.0\bin')
for i, image in enumerate(images):
    fname = 'image'+str(i)+'.png'
    image.save(fname, "PNG")

现在完成了。有了这个技巧，无需添加环境变量。如果您有任何问题，请告诉我。
