Sentence transformer gives loading error
I tried to run the sentence transformer example but it encountered loading error as follows:

Hi, what is your sentence-transformer version? FYI, I install the version 2.2.2
Hi, what is your sentence-transformer version? FYI, I install the version 2.2.2
Same, I am using 2.2.2 as well
Oh, you should use INSTRUCTOR to load the model:
from InstructorEmbedding import INSTRUCTOR
model = INSTRUCTOR('hkunlp/instructor-large')
For details, you may refer to https://github.com/xlang-ai/instructor-embedding#getting-started.

To solve this problem, use Sentence Transformer Module separately in your program..

from langchain.text_splitter import CharacterTextSplitter
from langchain.embeddings.openai import OpenAIEmbeddings
from langchain.embeddings.huggingface import HuggingFaceInstructEmbeddings

vectore_store = FAISS.from_texts(embedding=embeddings,texts=chunked_text)
return vectore_store
@utkarshkrc2 I got the following:
ValidationError: 1 validation error for HuggingFaceInstructEmbeddings
model_name
str type expected (type=type_error.str)
Which version of langchain are you using? I tested two versions (0.1.9 and the latest 0.1.11) but got the same problem with both. They don't accept SentenceTransformer as an argument.
@utkarshkrc2 , Even I am getting the same error:
ValidationError: 1 validation error for HuggingFaceInstructEmbeddings model_name str type expected (type=type_error.str)
Below is the code I am using:
def get_vectorstore(text_chunks):
model = SentenceTransformer('hkunlp/instructor-xl') #choosing different models does not make a different, tried with thenlper/gte-base and hkunlp/instructor-large
model_kwargs = {'device': 'cpu'} #changing the device to gpu didn't make any difference
encode_kwargs = {'normalize_embeddings': True}
embeddings = HuggingFaceInstructEmbeddings(model_name=model,model_kwargs=model_kwargs,encode_kwargs=encode_kwargs)
#embeddings = HuggingFaceInstructEmbeddings(model_name="hkunlp/instructor-xl")
vectorstore = FAISS.from_texts(texts=text_chunks, embedding=embeddings)
return vectorstore
Following is the version of langchain and sentence-transformers I am using.
Name: sentence-transformers
Version: 2.5.1
Name: langchain
Version: 0.1.12
This error comes after it processes the pdf to and finishes generating some of the embeddings, you can see that from the below logs:

Would be really helpful if someone has any idea why I get this error.
Hi, Everyone
Please Use the required Version of Hugging Face Transformer as I used.
Also, For Validation Error Please install python "Setuptools" Package.
Please Ping me, if it is working or not in your case. I also got the same error while executing my program.
@utkarshkrc2 , thanks for replying. I did try to downgrade the sentence-transformers version to 2.2.2 as I did notice some threads with similar issues and it helped to use this version, however there are other dependencies I am using which didn't work with this.
I will try to downgrade the other dependencies also and test it with that.
Do you know if its a bug with newer version of sentence-transformers?
@utkarshkrc2 , so I fixed the dependencies and got the version of sentence-transformers version to 2.2.2, it seems to have passed through the previous error but now I get this error:
File "/test/LangchainApp.py", line 48, in get_vectorstore

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/test/.venv/lib/python3.12/site-packages/sentence_transformers/models/Pooling.py", line 120, in load
return Pooling(**config)
^^^^^^^^^^^^^^^^^
Please let me if know if you can help, I can ping you (do let me know how).
@utkarshkrc2 , FYI, the code you showed in your comment does not work. Even with sentence-transformers version 2.2.2 and langchain version of 0.1.2, we get the "TypeError: Pooling.init() got an unexpected keyword argument 'pooling_mode_weightedmean_tokens'" error.
If we change the config.json used by Pooling.py file and remove 'pooling_mode_weightedmean_tokens' and 'pooling_mode_lasttoken' as per https://huggingface.co/hkunlp/instructor-base/discussions/6, we are back to the original error of 'ValidationError: 1 validation error for HuggingFaceInstructEmbeddings model_name str type expected (type=type_error.str)'.
Still trying to figure out how to solve this.
Edit: It worked for me after changing the HuggingFaceInstructEmbeddings constructor with only the model name and no other arguments. Also I didn't need to downgrade langchain version, I am still using 0.1.13.
HuggingFaceInstructEmbeddings(model_name="hkunlp/instructor-xl")
Hi, I am getting
TypeError: INSTRUCTOR._load_sbert_model() got an unexpected keyword argument 'token'
I am using langachain==0.1.2 and sentence-transformers==2.2.2
langchain_huggingface
tesnsorboard
tensorflow
setuptools
transformer_sentence 2.2.2
instructor
embeddinginstructor
embeddings
transformer
this are the one need to be installed on my case
any update with new version?
not the transformer_sentence 2.2.2
I already update, it is still exist problem.
InstructorEmbedding==1.0.1
sentence-transformers==3.0.1
Works for me.
