У меня есть чат веб-приложения и сервер Rasa , который является чат-ботом, и я хочу, чтобы чат-бот обрабатывал сообщение, полученное от первого.
После запуска приложения впорт 8000 и rasa_nlu.server на порт 5000 У меня возникают сложности с тем, чтобы сервер обрабатывал сообщения.Действительно, на терминале app.py скрипт, который получил все маршруты:
* Detected change in '/home/mike/Programing/Rasa/myflaskapp/app.py', reloading
* Restarting with stat
* Debugger is active!
* Debugger PIN: 213-078-895
{'error': "No project found with name 'default'."}

127.0.0.1 - - [04/Jun/2018 17:28:12] "POST /chat HTTP/1.1" 200 -
{'error': 'Unable to initialize persistor'}

Вот частьиз app.py, который относится к обработке сообщений чата, скажите, есть ли необходимость, но я думаю, что это не самое главное:
@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..."})
Так что ошибка была от load_model_from_cloud в project.py :
...
class Project(object):
def __init__(self,
component_builder=None,
project=None,
project_dir=None,
remote_storage=None):
self._component_builder = component_builder
self._models = {}
self.status = 0
self._reader_lock = Lock()
self._loader_lock = Lock()
self._writer_lock = Lock()
self._readers_count = 0
self._path = None
self._project = project
self.remote_storage = remote_storage
...
def _load_model_from_cloud(self, model_name, target_path):
try:
from rasa_nlu.persistor import get_persistor
p = get_persistor(self.remote_storage)
if p is not None:
p.retrieve(model_name, self._project, target_path)
else:
raise RuntimeError("Unable to initialize persistor")
except Exception as e:
logger.warn("Using default interpreter, couldn't fetch "
"model: {}".format(e))
raise # re-raise this exception because nothing we can do now
Так что проблема в том, что я не установил remote_storage.Я даже не знаю, что это такое!
