我正在尝试使用 slate 库读取 pdf 文件，但它会引发此错误：

import slate

pdf = 'tabla9.pdf'

with open(pdf,encoding="utf-8") as f:

doc = slate.PDF(f)

for page in doc[:2]:
   print(page)

完全错误：

File "C:\Users\user\libro5.py", line 7, in <module>
doc = slate.PDF(f)
File "C:\Python3\lib\slate\classes.py", line 52, in __init__
self.parser = PDFParser(file)
File "C:\Python3\lib\site-packages\pdfminer\pdfparser.py", line 646, in 
__init__
PSStackParser.__init__(self, fp)
File "C:\Python3\lib\site-packages\pdfminer\psparser.py", line 189, in 
__init__
PSBaseParser.__init__(self, fp)
File "C:\Python3\lib\site-packages\pdfminer\psparser.py", line 134, in 
__init__
data = fp.read()
File "C:\Python3\lib\codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe2 in position 10:

classes.py，第 52 行：

    def __init__(self, file, password='', just_text=1, check_extractable=True, char_margin=1.0, line_margin=0.1, word_margin=0.1):
        self.parser = PDFParser(file)

pdfparser.py，第 646 行：

        PSStackParser.__init__(self, fp)

psparser.py，第 189 行：

class PSStackParser(PSBaseParser):

    def __init__(self, fp):
        PSBaseParser.__init__(self, fp)

psparser.py，第 134 行：

class PSBaseParser:

    """Most basic PostScript parser that performs only tokenization.
    """
    def __init__(self, fp):
        data = fp.read()

文件“C:\Python3\lib\codecs.py”，第 322 行，在 decode (result, used) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte位置 10 中的 0xe2：无效的继续字节：

def decode(self, input, final=False):
    # decode input (taking the buffer into account)
    data = self.buffer + input
    (result, consumed) = self._buffer_decode(data, self.errors, final)

我在 Windows 10 上使用 Python 3.7。

PDF 文件是二进制文件，不适合以带有编码的文本模式打开它。

尝试：

with open(pdf, "rb") as f:
