I am using the RasaNLUHttpInterpreter as stated here to start my server. I give the class all the 4 parameters required (model-name, token, server-name, and project-name). However, I always get the error, that apparently I am handing over 5 arguments (what I don’t really do). The error occurred since I updated my Rasa-Core and NLU to the latest version. However, as in docs, I feel that I use the method correctly. Does anyone have an idea what I am doing wrong or what’s happening here? Here is my run-server.py where I use the RasaNLUHttpInterpreter: import os from os import environ as env from gevent.pywsgi import WSGIServer from server import create_app from rasa_core import utils from rasa_core.interpreter import RasaNLUHttpInterpreter utils.configure_colored_logging("DEBUG") user_input_dir = "/app/nlu/" + env["RASA_NLU_PROJECT_NAME"] + "/user_input" if not os.path.exists(user_input_dir): os.makedirs(user_input_dir) nlu_interpreter = RasaNLUHttpInterpreter( 'model_20190702-103405', None, 'http://rasa-nlu:5000', 'test_project') app = create_app( model_directory = env["RASA_CORE_MODEL_PATH"], cors_origins="*", loglevel = "DEBUG", logfile = "./logs/rasa_core.log", interpreter = nlu_interpreter) http_server = WSGIServer(('0.0.0.0', 5005), app) http_server.serve_forever() I am using: rasa_nlu~=0.15.1 rasa_core==0.14.5

rasa-core_1 | Traceback (most recent call last): rasa-core_1 | File "run_server.py", line 23, in <module> rasa-core_1 | 'model_20190702-103405', None, 'http://rasa-nlu:5000', 'test-project') rasa-core_1 | TypeError: __init__() takes from 1 to 4 positional arguments but 5 were given chat-ui_1 | Starting the development server... chat-ui_1 | schul_cloud_cui_rasa-core_1 exited with code 1

I think that you’re not providing a valid enpoint or the path to you nlu model is not correct @threxx

[image] threxx: http://rasa-nlu:5000 here is the output for NLU in the console when I start the server: rasa-nlu_1 | 2019-07-02 12:13:58+0000 [-] Log opened. rasa-nlu_1 | 2019-07-02 12:13:58+0000 [-] Site starting on 5000 rasa-nlu_1 | 2019-07-02 12:13:58+0000 [-] Starting factory <twisted.web.server.Site object at 0x7f1e1b31b198> Doesn’t that mean it is running on 5000? I mean it worked before the update with that server. What would be the correct one?

But that does make sense to me, I mean why would it say, that I am giving 5 arguments if one is not correct? Wouldn’t that be another error msg?

I tried this now: nlu_interpreter = RasaNLUHttpInterpreter( model_name = env["RASA_NLU_MODEL_NAME"], token=env["RASA_NLU_SERVER_TOKEN"], server = env["RASA_NLU_SERVER_ADDRESS"], project_name = env["RASA_NLU_PROJECT_NAME"]) the env variables are from the dockerfile. When I do this, I get the following error: rasa-core_1 | Traceback (most recent call last): rasa-core_1 | File "run_server.py", line 20, in <module> rasa-core_1 | project_name = env["RASA_NLU_PROJECT_NAME"]) rasa-core_1 | TypeError: __init__() got an unexpected keyword argument 'token' chat-ui_1 | Starting the development server... chat-ui_1 | schul_cloud_cui_rasa-core_1 exited with code 1 However, this was once the code that worked before the update to Rasa-Core 0.14 and NLU to 0.15. What did change? What am I doing wrong?

Hi @threxx @Ahmed I think the problem lies in reading the documentation of the version 0.9.4 of rasa. With 0.14.5 the following is valid: *class* rasa_core.interpreter. RasaNLUHttpInterpreter ( *model_name: str = None* , *endpoint: rasa_core.utils.EndpointConfig = None* , *project_name: str = 'default'* ) This can be read here - docs and here - source . Maybe you should modify your code according to docs. If you need help with that, please let me know. Regards Julian

@JulianGerhard thanks for that documentation. It helped a bit. I updated my code like this: nlu_interpreter = RasaNLUHttpInterpreter( model_name=None, endpoint="http://rasa-nlu:5000", project_name="test_project") And that’s my new error message: rasa-core_1 | 2019-07-03 09:10:39 WARNING server - Failed to load any agent model. Running Rasa Core server with out loaded model now. load() got an unexpected keyword argument 'action_factory What is that “agent model”? And the “action factory”?

Hi @threxx actually you should have trained a model haven’t you? If you are using the models folder for it, there should be a subdirectory called “nlu”? Can you maybe post a screenshot of that directory? Regards

[image] This is my directory, I have a “model” folder in the rasa-core folder and “models” in my project folder in the rasa-nlu. Which one should I use?

Hello @threxx can you show me the error you’re getting when you launch your server ?
