pdfminer package: can't find exgtract_text function

[Pavel_47]

Hello,

Using pdfminer package I faced the following problem:

>>> from pdfminer import high_level
>>> extracted_text = high_level.extract_text(full_filename_inp, "", [4])
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    extracted_text = high_level.extract_text(full_filename_inp, "", [4])
AttributeError: module 'pdfminer.high_level' has no attribute 'extract_text'

But, according to documentation the function extract_text does exist in pdfminer package.
pdfminer package
Any suggestions ?
Thanks
