rasa-core：0.9.0a3
rasa-nlu：0.12.3
问题
我有一个网络应用程序聊天和一个作为聊天机器人的 Rasa 服务器，我希望聊天机器人处理从第一个接收到的消息。
在本教程结束时，可以读到路径是通过执行“run_server.bat”脚本启动以下命令来启动 RASA-NLU 服务器。加载自定义训练模型并开始监听端口 5000：
$ python -m rasa_nlu.server --path projects
我尝试了以下操作，但终端告诉我该端口已在使用中
(myFlaskAppenv) mike@mike-thinks:~/Programing/Rasa/myflaskapp$ python -m rasa_nlu.server --path ~/Programing/Rasa/myflaskapp

的确 ：
(myFlaskAppenv) mike@mike-thinks:~/Programing/Rasa/myflaskapp$ python app.py
* Serving Flask app "app" (lazy loading)

因此，当我尝试与聊天机器人交谈时，它让我在终端 lou 中输入app.py了包含所有路线的信息：
127.0.0.1 - - [04/Jun/2018 16:42:46] "GET /parse?q=hi HTTP/1.1" 404 -
HOUSTON ! WE GOT AN EXCETPITON !
Expecting value: line 1 column 1 (char 0)
127.0.0.1 - - [04/Jun/2018 16:42:46] "POST /chat HTTP/1.1" 200 -
这里是app.py指处理聊天机器人消息的部分，如果还有更多需要，请告诉我，但我认为这不是最重要的：
@app.route('/chat',methods=["POST"])
def chat():
try:
user_message = request.form["text"]
response = requests.get("http://localhost:5000/parse",params={"q":user_message})
response = response.json()
entities = response.get("entities")
topresponse = response["topScoringIntent"]
intent = topresponse.get("intent")
print("Intent {}, Entities {}".format(intent,entities))
if intent == "gst-info":
response_text = gst_info(entities)# "Sorry will get answer soon" #get_event(entities["day"],entities["time"],entities["place"])
elif intent == "gst-query":
response_text = gst_query(entities)
else:
response_text = get_random_response(intent)
return jsonify({"status":"success","response":response_text})
except Exception as e:
print("HOUSTON ! WE GOT AN EXCETPITON !")
print(e)
return jsonify({"status":"success","response":"Sorry I am not trained to do that yet..."})
那么，我应该使用什么命令让聊天机器人服务器开始监听和讨论端口 5000？
