How to use this model directly from the πŸ€—/transformers library:

			
Copy model
tokenizer = AutoTokenizer.from_pretrained("dbmdz/bert-base-italian-xxl-cased") model = AutoModelWithLMHead.from_pretrained("dbmdz/bert-base-italian-xxl-cased")

πŸ€— + πŸ“š dbmdz BERT models

In this repository the MDZ Digital Library team (dbmdz) at the Bavarian State Library open sources Italian BERT models πŸŽ‰

Italian BERT

The source data for the Italian BERT model consists of a recent Wikipedia dump and various texts from the OPUS corpora collection. The final training corpus has a size of 13GB and 2,050,057,573 tokens.

For sentence splitting, we use NLTK (faster compared to spacy). Our cased and uncased models are training with an initial sequence length of 512 subwords for ~2-3M steps.

For the XXL Italian models, we use the same training data from OPUS and extend it with data from the Italian part of the OSCAR corpus. Thus, the final training corpus has a size of 81GB and 13,138,379,147 tokens.

Model weights

Currently only PyTorch-Transformers compatible weights are available. If you need access to TensorFlow checkpoints, please raise an issue!

Usage

With Transformers >= 2.3 our Italian BERT models can be loaded like:

from transformers import AutoModel, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("dbmdz/bert-base-italian-cased")
model = AutoModel.from_pretrained("dbmdz/bert-base-italian-cased")

To load the (recommended) Italian XXL BERT models, just use:

from transformers import AutoModel, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained("dbmdz/bert-base-italian-xxl-cased")
model = AutoModel.from_pretrained("dbmdz/bert-base-italian-xxl-cased")

All models are available on the Huggingface model hub.
