The [HuggingFace Transformers example](https://github.com/allegroai/clearml/blob/master/examples/frameworks/huggingface/transformers.ipynb)
demonstrates how to integrate ClearML into your Transformer's PyTorch [Trainer](https://huggingface.co/docs/transformers/v4.34.1/en/main_classes/trainer)
code. When ClearML is installed in an environment, the Trainer by default uses the built-in [`ClearMLCallback`](https://huggingface.co/docs/transformers/v4.34.1/en/main_classes/callback#transformers.integrations.ClearMLCallback),
so ClearML automatically logs Transformers models, parameters, scalars, and more.
When the example runs, it creates a ClearML task called `Trainer` in the `HuggingFace Transformers` projects. To change
the tasks name or project, use the `CLEARML_PROJECT` and `CLEARML_TASK` environment variables respectively.
For more information about integrating ClearML into your Transformers code, see [HuggingFace Transformers](../../../integrations/transformers.md).
## WebApp
### Hyperparameters
ClearML automatically captures all the PyTorch trainer [parameters](https://huggingface.co/docs/transformers/v4.34.1/en/main_classes/trainer#transformers.TrainingArguments).
Notice in the code example that only a few of the `TrainingArguments` are explicitly set:
```python
training_args = TrainingArguments(
output_dir="path/to/save/folder/",
learning_rate=2e-5,
per_device_train_batch_size=8,
per_device_eval_batch_size=8,
num_train_epochs=2,
)
```
ClearML captures the arguments specified in the preceding code, as well the rest of the `TrainingArguments` and their default
values.
View the parameters in the experiment's **CONFIGURATION** tab **> Hyperparameters** section.

### Models
In order for ClearML to log the models created during training, the `CLEARML_LOG_MODEL` environment variable is set to `True`.
ClearML automatically captures the model snapshots created by the Trainer, and saves them as artifacts. View the snapshots in the
experiment's **ARTIFACTS** tab.

### Scalars
ClearML automatically captures the Trainer's scalars, which can be viewed in the experiment's **Scalars** tab.
