I am passing chat template as a configmap to vLLM via Kserve
Data
====
chat_template.json:
----
{% for message in messages %}
{% if message['role'] == 'user' %}
{{ 'User:
' + message['content'] }}
{% elif message['role'] == 'system' %}
{{ 'System: ' + message['content'] }}
{% elif message['role'] == 'assistant' %}
{{ 'Falcon:
' + message['content']}}
{% endif %}
{% if loop.last and add_generation_prompt %}
{{ 'Falcon:' }}
{% endif %}
{% endfor %}
Any idea what is missing here ?
