Error loading the swissprot saved model in python 3.6

[rainwala]

Hello,

I am trying your code (I installed via pip3), and when I try to load the swissprot model using this code:

import biovec

pv = biovec.models.load_protvec('biovec/swissprot-reviewed-protvec.model')
print(pv.to_vecs("ATATQSQSMTEEL"))

I get the error:

/home/aawan/.local/lib/python3.6/site-packages/smart_open/smart_open_lib.py:398: UserWarning: This function is deprecated, use smart_open.open instead. See the migration notes for details: https://github.com/RaRe-Technologies/smart_open/blob/master/README.rst#migrating-to-the-new-open-function

What version of biovec are you using? If it's not up-to-date, please update it first :)

I could not reproduce this error under this condition:

biovec 0.2.7 gensim 3.4.0 Python 3.6.7

Hi,

I am using biovec 0.2.7 gensim 3.4.8 Python 3.6.8

Should I try downgrading gensim?

Yeah let's make the versions same, also download the latest model file again. By the way, What OS are you using?
