@F02934 Hi, I remade the translation because the previous PR had problem with the commits history. You can check if everything good with the translation and with the toctree<|||||>Hi @F02934! Sorry for the late reply.

No worries! You simply have to edit the _toctree file, removing the empty sections, and adding a title, your _toctree file should look like this:

``` yaml
- sections:
  - local: index
    title: 🤗 Transformers
  - local: quicktour
    title: Tour rapido
  - local: installation
    title: Installazione
  title: Iniziare
- sections:
  - local: pipeline_tutorial
    title: Pipeline per l'inferenza
  - local: autoclass_tutorial
    title: Carica istanze pre-allenate con AutoClass
  title: Esercitazione
- sections:
  - local: troubleshooting
    title: Risoluzione dei problemi
  title: Guide pratiche
```

I forgot to add a section and to translate the last title!<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.
