尝试使用Dora-rs
Python Conversation
https://dora-rs.ai/zh-CN/docs/guides/getting-started/conversation_py
-
创建一个新的数据流
dora new conversation_py --lang python cd conversation_py
-
添加一个新的节点
dora new --kind custom-node talker
-
在创建的新节点里创建并编辑talker.py
加入以下内容:
from dora import Node import pyarrow as pa node = Node() event = node.next() if event["type"] == "INPUT": print( f"""Node received: id: {event["id"]}, value: {event["value"]}, metadata: {event["metadata"]}""" ) node.send_output("speech", pa.array(["Hello World"])) # add this line
-
调整监听节点
将node_1的名称更改为listener, 将node_1.py的名称更改为listener.py
内容变为:
from dora import Node import pyarrow as pa node = Node() event = node.next() if event["type"] == "INPUT": message = event["value"][0].as_py() print( f"""I heard {message}""" )
-
修改dataflow.yml文件
变为:
nodes: - id: talker custom: source: talker/talker.py inputs: tick: dora/timer/secs/1 outputs: - speech - id: listener custom: source: listener/listener.py inputs: speech: talker/speech
之后在终端运行:
dora up
dora start dataflow.yml --name conversation
dora logs conversation listener
结果:
root@Phytium-Pi:/home/user/conversation_py# dora logs conversation listener
I heard Hello World
