Yeah I’m having the same issue using the API to send requests in Unity. Even using the inference provider from the model page directly results in the same error sentence-transformers/all-MiniLM-L6-v2 · Hugging Face. It also seems to persist with a lot of the other sentence transformers.

I’m getting 404 errors using InferenceClient() on meta-llama/Llama-3.3-70B-Instruct, meta-llama/Llama-3.1-8B-Instruct, Mixtral-8x7B-Instruct-v0.1, and mistralai/Mistral-7B-Instruct-v0.3. Basically any InferenceClient() calls! Am I not alone in this?

Same here… @michellehbn

For those stuck with HF, get a free Mistral account to get the API key. Then you can use this class to do text generation. The chat_stream() will simulate the packets HF’s InferenceClient() would return, so it can be a plug and play…

from mistralai import Mistral

class TextPacket:
    def __init__(self):
        self.choices = []

class TextMessage:
    def __init__(self):
        self.role:str = None
        self.content:str = None

class TextGroup:
    def __init__(self):
        self.index = 0
        self.finish_reason:str = None
        self.delta:TextMessage = TextMessage()
        self.message:TextMessage = TextMessage()

class MistralGenerator():
    def __init__(self):
        self.api_key = config.MISTRALAI_APIKEY
        self.model = "mistral-small-latest"
        self.client = Mistral(api_key=self.api_key)

    def chat_complete(self, query, max_tokens=512, temperature=0.7, top_p=0.9):
        chat_response = self.client.chat.complete(

        )
        print(chat_response.choices[0].message.content)

Perhaps resolved?

Maybe fixed. From HF Discord:

Tom Aarsen
I’ve asked internally, and they indeed reported an issue, but it has been resolved now! Apologies

8

Yes, the issue with the sentence transformers has been fixed now.

I seem to still be getting this. Anyone else or is it just me? I don’t think it’s a token issue. The error message is not very helpful either:

curl -X POST -H ‘Accept: application/json’ -H ‘Content-Type: application/json’ -H ‘Authorization: XXXX’ -d ‘{“inputs”:[“What is fraud”],“options”:{“wait_for_model”:true}}’ ‘https://api-inference.huggingface.co/pipeline/feature-extraction/sentence-transformers/all-MiniLM-L6-v2’

{“status”:422,“body”:{“status_code”:404,“message”:“Unexpected token ‘N’, "Not Found" is not valid JSON”,“payload”:“Not Found”}}

As for SentenceTransformers, I think it’s probably in this state.
