Description

When using query.py from serving the following appears. It looks like tensorflow' has no attribute 'bytes'. What does it mean?

Traceback (most recent call last):

what model you trained?

[JakubSido]

It was transformer-encoder or seq2seq-encoder.

Not sure that's the cause of this but query.py is Py2 only.
