Hi @F02934 ❤️ Thanks for your contribution! The reason why the code does not pass the tests is related to the fact that the file you create with the translation must be called exactly by the name in the toctree under "local:", in this case in local it says create_a_model while your file is create_model.

While I'm at it, I'd like to ask you if you can also translate the part in the _toctree called "title" for example with: "Crea un'architettura personalizzata". I will now take a moment to look at the rest of the PR, thank you 🌈🌈🌈<|||||>Alright I will correct it!<|||||>_The documentation is not available anymore as the PR was closed or merged._<|||||>@mfumanelli Done!:)<|||||>Hi @F02934, I have just had a look at your file, I ask you if you can edit these things:
- "Crea un architettura personalizzata" --> "Crea un'architettura personalizzata"
- "chiunque sia interessato nel studiare" --> "qualunque persona sia interessata nel studiare" (to keep the text more gender-neutral)
- "Creare un architettura modello" --> "Creare un'architettura per un modello"
- "Creare un tokenizer per testo lento e veloce" --> "Creare un tokenizer lento e veloce per il testo"
- "Una configuration si riferisce agli" --> "Una configurazione si riferisce agli"
- "Dai un'occhiata piu vicino a" --> "Dai un'occhiata più da vicino a"
- "creando uno spazion per sperimentare" --> "creando uno spazio per sperimentare"
- "Utilizzare tasso di drop out più elevato per le probalità di attenzione con il parametro attention_dropout" --> "Utilizzare un tasso di dropout più elevato per le probabilità di attention con il parametro attention_dropout"
- "la configurazione del modello ti soddisfa, lo puoi salvare con" --> "la configurazione del modello ti soddisfa, la puoi salvare con"
- "Il file della tua configurazione e memorizzato" --> "Il file della tua configurazione è memorizzato"
- "Il prossimo passo e di creare model." --> "Il prossimo passo è creare un modello."
- "sono usati per definire l'archittetura" --> "sono usati per definire l'architettura"
- "soppressione dei self-attention heads" --> "soppressione delle self-attention heads"
- "Questo significa che i modelli sono compatibili con ciascuno dei rispettivi utilizzi del framework" --> "Ciò significa che i modelli sono compatibili con l'uso di ciascun framework."
- "la configurazione del modello predefinito è automaticamente caricato" --> "la configurazione del modello predefinito è automaticamente caricata"
- "puoi ancora sostituire - alcuni o tutti - gli attributi di configurazion del modello predefinito con i tuoi se lo desideri:" --> "puoi ancora sostituire gli attributi - alcuni o tutti - di configurazione del modello predefinito con i tuoi se lo desideri:"
(these last corrections above for both pytorch and tf)
- edit this everywhere "modello head" with "model head"
- "hai un modello DistilBERT base in cui output sono gli hidden states" --> "hai un modello DistilBERT base i cui output sono gli hidden states"
- "DistilBERT base con la sequenza di classificazione head" --> "DistilBERT base con una testa di classificazione per sequenze"
- edit this everywhere "sequenza di classificazione head" with "testa di classificazione per sequenze"
- "per un altra attività" --> "per un'altra attività"
- "ad un modello head diverso" --> "ad una model head differente"
- "Il head di risposta alle domande" --> "La head per compiti di question answering"
- "un occhiata a questo table" --> "un'occhiata a questa tabella"
- "tuo file vocabulario:" --> "tuo file vocabolario:"
- "Per impostazione predefinita" --> "Per l'impostazione predefinita"

thank you very much! 🚀🚀<|||||>@mfumanelli of course I will look into it<|||||>hello @mfumanelli I edited the things you asked, you can check if everything is alright. I also made a mistake and commited here  another translation I was doing but it's small (I added the serialization on _toctree.yml and mistakenly commited here). What should I do?<|||||>Hi @F02934! You can simply remove the file from your repo locally and re-commit and push. Or if you prefer, add "WIP" to the PR title and also add to the PR description that you are translating the serialization file 😊<|||||>Alright I will remove the file from my local repo and re-commit push<|||||>@mfumanelli everything good know! You can check if there is any problems<|||||>Hello @mfumanelli I finished another translation (serialization.mdx) But I don't know why it keep pushing to this pull request.
<|||||>I changed the PR describe that I also translated serialization.mdx here<|||||>Hi @F02934!! I was just about to reply to you! Your PR keeps updating because you are working on the main of the forked repo. If you create a branch for each file you translate, this doesn't happen. I'll also look at the new file later, sorry I didn't reply sooner 😊<|||||>@mfumanelli ok sorry I'm still new thank you for answering. So I need to create another branch each time I'm working on a new translation rigth?<|||||>Don't worry @F02934 ❤️ Yes, that's right, then you delete the branch every time they merge your PR (there's actually an option to delete it once they merge it)<|||||>@mfumanelli hi , just wondering if you forgot about this pr 🧑‍💻<|||||>Hi @F02934, no! It will be approved, there are several PRs in the stack, don't worry ❤️<|||||>cc @omarespejel <|||||>> cc @omarespejel 

Hi what does it mean?<|||||>Hi @F02934 could you solve conflicts, please?
I think they are in the _toctree.yml because some PRs have been merged and the file has updated.
