pyPDF2“流意外结束”
pyPDF2“流意外结束”
提问于 2022-03-31 17:27:02
这是我的第一个python代码。作者传递了一个错误。这似乎是随机发生在循环过程中，通过pdf的。
try: except: pass将无法工作，因为它只会跳过该问题的文件，而不会为它生成一个输出。
strict=False似乎不适合作者。
错误：

PdfReadWarning: Multiple definitions in dictionary at byte 0x75740 for key /PageMode [generic.py:587]

raise PdfStreamError("Stream has ended unexpectedly")
PyPDF2.utils.PdfStreamError: Stream has ended unexpectedly我读过几篇关于需要在读取器中放置strict=False以传递警告而不是错误的帖子。https://stackoverflow.com/questions/42570432/pypdf2-stream-has-ended-unexpectedly，https://github.com/mstamy2/PyPDF2/issues/99.然而，在大多数情况下，作者现在似乎是问题所在。
事先谢谢您的建议。
供参考的循环片段：
for file in input_pdf:
output_pdf = PdfFileWriter()
sg.OneLineProgressMeter('My Meter', i, page_count, 'And now we Wait.....')
PageObj = PyPDF2.PdfFileReader(open(file, "rb"), strict=False).getPage(0)
PageObj.scaleTo(11*72, 17*72)
PageObj.mergePage(Seal_pdf.getPage(0))
output_pdf.addPage(PageObj)
output_filename = f"{file}"
f = open(output_filename, "wb+")
output_pdf.write(f)
i = i + 1

由于来自@cards和@KJ的有用输入，我发现问题在于我试图覆盖一个正在使用的文件。原作仍被记在记忆中，这一事实一旦传到作者的记忆中就会败坏。只需将文件保存在不同的名称下，并编写更多的代码来清理目录，这就是我所使用的解决方案。谢谢你的协助。
