提示注册表示例

本页提供了提示注册表操作的例子。

register_prompt（）

API 参考：mlflow.genai.register_prompt

prompt = mlflow.genai.register_prompt(
    name="mycatalog.myschema.summarization",
    template="""Summarize the following text in {{num_sentences}} sentences:

Text: {{content}}

Focus on: {{focus_areas}}""",
    commit_message="Added focus areas parameter",
    tags={
        "tested_with": "gpt-4",
        "avg_latency_ms": "1200",
        "team": "content",
        "project": "summarization-v2"
    }
)

load_prompt（）

API 参考：mlflow.genai.load_prompt

以下示例使用 URI 格式加载特定版本

# Load specific version using URI format
v2 = mlflow.genai.load_prompt(name_or_uri="prompts:/mycatalog.myschema.qa_prompt/2")

# Load specific version using name + version parameter
v3 = mlflow.genai.load_prompt(name_or_uri="mycatalog.myschema.qa_prompt", version=3)

# Load with allow_missing flag (returns None if not found)
optional_prompt = mlflow.genai.load_prompt(
    name_or_uri="mycatalog.myschema.qa_prompt",
    version=3,
    allow_missing=True
)

# Use the prompt
if optional_prompt is not None:
    response = llm.invoke(optional_prompt.format(
        question="What is MLflow?",
        context="MLflow is an open source platform..."
    ))

以下示例使用 URI 格式按别名加载

# Load by alias using URI
prod = mlflow.genai.load_prompt(name_or_uri="prompts:/mycatalog.myschema.qa_prompt@production")

# Load with allow_missing flag (returns None if not found)
optional_prompt = mlflow.genai.load_prompt(
    name_or_uri="mycatalog.myschema.qa_prompt",
    version=3,
    allow_missing=True
)

# Use the prompt
if optional_prompt is not None:
    response = llm.invoke(optional_prompt.format(
        question="What is MLflow?",
        context="MLflow is an open source platform..."
    ))

search_prompts（）

API 参考：mlflow.genai.search_prompts

Unity Catalog 要求

对于 Unity 目录提示注册表，必须同时指定目录和架构：

# REQUIRED format - list all prompts in a catalog.schema
results = mlflow.genai.search_prompts("catalog = 'mycatalog' AND schema = 'myschema'")

# This is the ONLY supported filter format
results = mlflow.genai.search_prompts("catalog = 'rohit' AND schema = 'default'")

局限性

Unity 目录中不支持以下筛选器：

• 名称模式： name LIKE '%pattern%'
• 标签过滤：tags.field = 'value'
• 确切的名称匹配： name = 'specific.name'
• 超越目录和架构的组合筛选器

若要查找特定提示，请使用返回的列表并以编程方式进行筛选：

# Get all prompts in schema
all_prompts = mlflow.genai.search_prompts("catalog = 'mycatalog' AND schema = 'myschema'")

# Filter programmatically
customer_prompts = [p for p in all_prompts if 'customer' in p.name.lower()]
tagged_prompts = [p for p in all_prompts if p.tags.get('team') == 'support']

set_prompt_alias（）

API 参考：mlflow.genai.set_prompt_alias

# Promote version 3 to production
mlflow.genai.set_prompt_alias(
    name="mycatalog.myschema.chat_assistant",
    alias="production",
    version=3
)

# Set up staging for testing
mlflow.genai.set_prompt_alias(
    name="mycatalog.myschema.chat_assistant",
    alias="staging",
    version=4
)

delete_prompt（） 和delete_prompt_version（）

delete_prompt_version()

API 参考：MlflowClient.delete_prompt_version

删除提示的特定版本：

from mlflow import MlflowClient

client = MlflowClient()

# Delete specific versions first (required for Unity Catalog)
client.delete_prompt_version("mycatalog.myschema.chat_assistant", "1")
client.delete_prompt_version("mycatalog.myschema.chat_assistant", "2")
client.delete_prompt_version("mycatalog.myschema.chat_assistant", "3")

# Then delete the entire prompt
client.delete_prompt("mycatalog.myschema.chat_assistant")

# For convenience with Unity Catalog, you can also search and delete all versions:
search_response = client.search_prompt_versions("mycatalog.myschema.chat_assistant")
for version in search_response.prompt_versions:
    client.delete_prompt_version("mycatalog.myschema.chat_assistant", str(version.version))

client.delete_prompt("mycatalog.myschema.chat_assistant")

delete_prompt()

删除提示版本后，可以删除提示。

API 参考：MlflowClient.delete_prompt

from mlflow import MlflowClient

client = MlflowClient()

# Delete specific versions first (required for Unity Catalog)
client.delete_prompt_version("mycatalog.myschema.chat_assistant", "1")
client.delete_prompt_version("mycatalog.myschema.chat_assistant", "2")
client.delete_prompt_version("mycatalog.myschema.chat_assistant", "3")

# Then delete the entire prompt
client.delete_prompt("mycatalog.myschema.chat_assistant")

# For convenience with Unity Catalog, you can also search and delete all versions:
search_response = client.search_prompt_versions("mycatalog.myschema.chat_assistant")
for version in search_response.prompt_versions:
    client.delete_prompt_version("mycatalog.myschema.chat_assistant", str(version.version))

client.delete_prompt("mycatalog.myschema.chat_assistant")
