No Module named tika

Hi,

Thank you, for sharing such a good and self-declarative notebook...! I have got an error I am appending below:

`

Hi @ArghyaPal ,

I'm assuming this means you haven't installed all the python dependencies yet, in particular tika. Please see the installation instructions in the README here!

Hi Alex, Thank you for your quick reply. Yes, now it's working fine. But, I am getting another issue, when I was trying the block :

from snorkel.parser import CorpusParser from utils import TaggerOneTagger tagger_one = TaggerOneTagger() corpus_parser = CorpusParser(fn=tagger_one.tag) corpus_parser.apply(list(doc_preprocessor))

of CDR_Tutorial_1

The error is: TypeError: unsupported operand type(s) for -=: 'Retry' and 'int'

Thank you again, Regards, Arghya

Hm, I'm unsure of what this error is... we run this tutorial through automated tests and we're not getting any errors here. Could you provide any other details on what's going wrong?

Hi, it's my installation fault. Sorry for this. Thank you for your help and quick response
