Hi all, i have used HFTransformersNLP for train NLU, but with init model_weights is “vinai/phobert-base” and WhitespaceTokenizer ===> tokenizer.encode return NoneType alway . this line error lib\site-packages\transformers\tokenization_utils_base.py", line 2654
@tacsenlp can you please share the config.yml
file for the ref? and what command you are using when you see this error message?
@tacsenlp can you please format the config.yml file thanks.
@tacsenlp Right!
Alert:
The HFTransformersNLP
is deprecated and will be removed in 3.0. The LanguageModelFeaturizer now implements its behavior.
Solution:
To use HFTransformersNLP
component, install Rasa Open Source with pip3 install rasa[transformers]
.
Or if you are aware of this, please share screenshot of error message.
I guess this will solve your issue bro! Good Luck!
i am using rasa 2.8.7
@tacsenlp you can even try this
model_weights: "rasa/LaBSE"
i want use for “Vietnamese” language , LaBSE not comfortable
@tacsenlp ohh, you not mentioned that, ok let me see the solution for you.
thanks you !!
@tacsenlp meanwhile check this paper: (PDF) Enhancing Rasa NLU model for Vietnamese chatbot focus on the pipeline mentioned.
@tacsenlp Even check this of my solution thread: Rasa Train Error Function call stack: train_on_batch - #15 by trinhminhhieu
@tacsenlp Even check this: [ASK] Process get killed when training RASA core - #9 by nik202
I hope this will solve your issue.
@nik202 bert-base-multilingual-cased is support , but phobert-base is best for vi language… thanks you so much!!!
@tacsenlp Right, good to know please can I request to close this thread as a solution for other Vietnamese user and for your reference and good luck!
@nik202 i have problem. i don’t know debug trainer NLU, example: i want see vector before train, how to do this…
@tacsenlp can I ask why you want to see that and what is the significance for the same?
@nik202 this is as example of me… debug tokenizer, feature,… i want check …my custom compnents is right
@nik202 and… when i response by utter in domain.yml is fast(200-300ms)… but response by custom action is slow (2-3s) although only simple message
@tacsenlp I not get you still? you want to see the data of conversation or what? me confused with vector (it for me means dense vector )
@tacsenlp it natural phenomenon. What is your frontend or you just using rasa shell --debug
@nik202 i just using rasa shell --debug
@tacsenlp I did not get what you are looking for apologies, if you have something to share please share.
