Can not load tokoenizer from_pretrained through http_proxy since 0.14.0

[jtsai-quid]

Hi hf,

I encountered an issue where I couldn't load the tokenizer using from_pretrained via the http_proxy in version 0.14.0, while it worked successfully in version 0.13.3.
This caused the fast tokenizer initialization issue in TGI 1.1.0.
huggingface/text-generation-inference#1108

Here is the code snippet that I use to test for testing.

//# tokenizers = { version = "0.14.0", features = ["http"] }

use tokenizers::tokenizer::{Result, Tokenizer};
use tokenizers::{FromPretrainedParameters};

fn main() -> Result<()> {
        let authorization_token = std::env::var("HUGGING_FACE_HUB_TOKEN").ok();
        let params = FromPretrainedParameters {
            revision: None.clone().unwrap_or("main".to_string()),
            auth_token: authorization_token.clone(),
            ..Default::default()
        };

        let tokenizer = Tokenizer::from_pretrained("TheBloke/Llama-2-13B-chat-GPTQ", Some(params))?;

        let encoding = tokenizer.encode("Hey there!", false)?;
        println!("{:?}", encoding.get_tokens());
    Ok(())
}

Error output

I suspect that this is related to the client refactoring in here

Thanks and appreciate for any help from you!

Indeed. Could you try with the latest release? Otherwise I'll have look at what I can do!

[jtsai-quid]

Just try the version 0.14.1 and the error still occurs. 😞

hi @ArthurZucker ,
Would this PR fix this issue?
huggingface/hf-hub#34

[ArthurZucker]

Ah! Yeah most probably because now we use the hf-hub api to load files, so if proxy is an issue there, will affect us.

hi @ArthurZucker ,
I have noticed hf-hub has fixed this issue.
huggingface/hf-hub#34
Would it be possible to use the latest version of hf-hub in the tokenizer?
Thanks~
