当前行为 | Current Behavior

我在self_pdf_loader.py在添加了这么几行代码，用来测试解析pdf的效果
file_path = 'cat.pdf'
file_path = os.path.abspath(os.path.join(os.path.dirname(file), file_path))
loader = PdfLoader(filename=file_path, from_page=14, to_page=15, root_dir=os.path.dirname(file_path))
markdown_dir = loader.load_to_markdown()
docs = convert_markdown_to_langchaindoc(markdown_dir)
docs = PdfLoader.pdf_process(docs)
print(docs)

但是却碰到了检索不到checkpoints的问题

好的十分感谢，另外是不是Qanything无法处理没有文本元素的pdf啊，我截了一张图进行解析，发现有报错。如果是这样那它里面的ocr的意义是什么呢，是解析表格？

The OCR module was removed due to slowly processing speed , and it can currently only handle parseable pdf files. Support for scanning image-based pdf files will be added in the future through a toggle switch.

好的好的，十分感谢。既然不会ocr pdf，那感觉可以把pdf loader里面的ocr相关的东西先去掉，不然很迷惑人哈哈哈，明明都输出ocr finished了，但是实际上却没有ocr

同感 上传一个单层PDF只有图片 就悲剧了 box找不到 直接报错 跟代码发现没有OCR

我也真是无语了

我也是一样的错误：Error in Powerful PDF parsing: max() arg is an empty sequence。关键是我传的是一页论文pdf，不是图片

可以使用ocrmypdf 处理pdf。
