### Multi GPU CTC with Dataset Streaming
The following command shows how to use [Dataset Streaming mode ](https://huggingface.co/docs/datasets/dataset_streaming.html )
to fine-tune [XLS-R ](https://huggingface.co/transformers/master/model_doc/xls_r.html )
on [Common Voice ](https://huggingface.co/datasets/common_voice ) using 4 GPUs in half-precision.
Streaming mode imposes several constraints on training:
1. We need to construct a tokenizer beforehand and define it via `--tokenizer_name_or_path` .
2. `--num_train_epochs` has to be replaced by `--max_steps` . Similarly, all other epoch-based arguments have to be
replaced by step-based ones.
3. Full dataset shuffling on each epoch is not possible, since we don't have the whole dataset available at once.
However, the `--shuffle_buffer_size` argument controls how many examples we can pre-download before shuffling them.
