Examples
Version 2.9 of 🤗 Transformers introduces a new Trainer
class for PyTorch, and its equivalent TFTrainer
for TF 2.
Running the examples requires PyTorch 1.3.1+ or TensorFlow 2.1+.
Here is the list of all our examples:
- grouped by task (all official examples work for multiple models)
- with information on whether they are built on top of
Trainer
/TFTrainer
(if not, they still work, they might just lack some features), - whether they also include examples for
pytorch-lightning
, which is a great fully-featured, general-purpose training library for PyTorch, - links to Colab notebooks to walk through the scripts and run them easily,
- links to Cloud deployments to be able to deploy large-scale trainings in the Cloud with little to no setup.
This is still a work-in-progress – in particular documentation is still sparse – so please contribute improvements/pull requests.

Important note
Important To make sure you can successfully run the latest versions of the example scripts, you have to install the library from source and install some example-specific requirements. Execute the following steps in a new virtual environment:
git clone https://github.com/huggingface/transformers
cd transformers
pip install .
pip install -r ./examples/requirements.txt

Running on TPUs
When using Tensorflow, TPUs are supported out of the box as a tf.distribute.Strategy
.
When using PyTorch, we support TPUs thanks to pytorch/xla
. For more context and information on how to setup your TPU environment refer to Google's documentation and to the
very detailed pytorch/xla README.
In this repo, we provide a very simple launcher script named xla_spawn.py that lets you run our example scripts on multiple TPU cores without any boilerplate.
Just pass a --num_cores
flag to this script, then your regular training script with its arguments (this is similar to the torch.distributed.launch
helper for torch.distributed).
For example for run_glue
:
python examples/xla_spawn.py --num_cores 8 \
examples/text-classification/run_glue.py
--model_name_or_path bert-base-cased \
--task_name mnli \
--data_dir ./data/glue_data/MNLI \
--output_dir ./models/tpu \
--overwrite_output_dir \
--do_train \
--do_eval \
--num_train_epochs 1 \
--save_steps 20000
Feedback and more use cases and benchmarks involving TPUs are welcome, please share with the community.
