我正在尝试使用slate库读取pdf文件,但会引发此错误:

import slate

pdf = 'tabla9.pdf'

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

doc = slate.PDF(f)

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

完整错误:

文件“ C:\ Python3 \ lib \ codecs.py”,第322行,在解码中     (结果,消耗)= self._buffer_decode(数据,self.errors,最终) UnicodeDecodeError:'utf-8'编解码器无法解码位置10的字节0xe2:无效的继续字节:

我正在Windows 10上使用Python 3.7。

PDF文件是二进制文件,因此不适合在带有编码的文本模式下打开它。

尝试:

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