Error when running example script EToKi.py MLSTdb

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 2020-07-29 20:45:04.997470 Exemplar sequences in ./NS_2085r4ap/clsFna.clust.exemplar 2020-07-29 20:45:04.997569 Clusters in ./NS_2085r4ap/clsFna.clust.tab 2020-07-29 20:45:05.030599 Run BLASTn starts 2020-07-29 20:45:05.384751 Run BLASTn finishes.

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