Can't get Config to work on this Bert based models.

[martin-conur]

I want to implement this model for text summarization:
option 1: mrm8488/bert2bert_shared-spanish-finetuned-summarization
option 2: "Narrativa/bsc_roberta2roberta_shared-spanish-finetuned-mlsum-summarization

I'm using the following:

use candle_transformers::models::bert::Config;

let config = std::fs::read_to_string(config_filename)?;
let mut config: Config = serde_json::from_str(&config)?;

But I get this error: missing field hidden_size at line 171 column 1

I suppose that doesn't have the same structure that it needs.
