Error when running example script EToKi.py MLSTdb

[theInnuendoProject]

Hello,
I installed EToKi and tried the example as showed in the README file but I got the following error.

./EToKi.py MLSTdb -i examples/Escherichia.Achtman.alleles.fasta -r examples/Escherichia.Achtman.references.fasta -d examples/Escherichia.Achtman.convert.tab

I installed in a conda env with python 3.6.
Some ideas how to fix it?
