当我在python IDLE中运行这些代码时，我得到了这个警告，如何解决这个问题？
警告：root：找不到objid = nnn
# -*- coding: utf-8 -*-
from pdfminer.pdfinterp import PDFResourceManager, process_pdf
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from io import StringIO
from io import open
def readPDF(pdfFile):
rsrcmgr = PDFResourceManager()
retstr = StringIO()
laparams = LAParams()
device = TextConverter(rsrcmgr, retstr, laparams=laparams)
process_pdf(rsrcmgr, device, pdfFile)
device.close()
content = retstr.getvalue()
retstr.close()
return content
def saveTxt(txt):
with open("xxx.txt", "w",encoding="utf-8") as f:
f.write(txt)
txt = readPDF(open('xxx.pdf', 'rb'))
saveTxt(txt)
当我将STRICT = True添加到psparser.py并运行程序时，它会返回如下：
