          Curious, What's the correct TEMPLATE parameter for google gemma model, in the context of modelfile? I am converting GGUF to ollama by myself by using the command "ollama crea xxx -f xxx"

the original hugingface repo chat_template is as follows

{% if messages[0]['role'] == 'system' %}
{{ raise_exception('System role not supported') }}
{% endif %}

{% for message in messages %}
	{% if (message['role'] == 'user') != (loop.index0 % 2 == 0) %}
		{{ raise_exception('Conversation roles must alternate user/assistant/user/assistant/...') }}
	{% endif %}
	{% if (message['role'] == 'assistant') %}
		{% set role = 'model' %}
	{% else %}
		{% set role = message['role'] %}
	{% endif %}
	
	{{ '<start_of_turn>' + role + '\n' + message['content'] | trim + '<end_of_turn>\n' }}
{% endfor %}

{% if add_generation_prompt %}{{'<start_of_turn>model\n'}}{% endif %}

The chat_template is a jinja template, which looks similar to the golang template langue used in ollama but is not compatible.
