Optimum Neuron

🤗 Optimum Neuron is the interface between the 🤗 Transformers library and AWS Accelerators including AWS Trainium and AWS Inferentia. It provides a set of tools enabling easy model loading, training and inference on single- and multi-Accelerator settings for different downstream tasks. The list of officially validated models and tasks is available here. Users can try other models and tasks with only few changes.

Install

To install the latest release of this package:

For AWS Trainium (trn1) or AWS inferentia2 (inf2)

pip install --upgrade-strategy eager optimum[neuronx]

For AWS inferentia (inf1)

pip install --upgrade-strategy eager optimum[neuron]

Optimum Neuron is a fast-moving project, and you may want to install it from source:

pip install git+https://github.com/huggingface/optimum-neuron.git

Alternatively, you can install the package without pip as follows:

bash
1git clone https://github.com/huggingface/optimum-neuron.git 2cd optimum-neuron 3python setup.py install

Make sure that you have installed the Neuron driver and tools before installing optimum-neuron, more extensive guide here.

Last but not least, don't forget to install the requirements for every example:

bash

cd <example-folder>
pip install -r requirements.txt

Quick Start

🤗 Optimum Neuron was designed with one goal in mind: to make training and inference straightforward for any 🤗 Transformers user while leveraging the complete power of AWS Accelerators.

Training

There are two main classes one needs to know:

TrainiumArgumentParser: inherits the original HfArgumentParser in Transformers with additional checks on the argument values to make sure that they will work well with AWS Trainium instances.
NeuronTrainer: this version trainer takes care of doing the proper checks and changes to the supported models to make them trainable on AWS Trainium instances.

The NeuronTrainer is very similar to the 🤗 Transformers Trainer, and adapting a script using the Trainer to make it work with Trainium will mostly consist in simply swapping the Trainer class for the NeuronTrainer one. That's how most of the example scripts were adapted from their original counterparts.

diff

from transformers import TrainingArguments
+from optimum.neuron import NeuronTrainer as Trainer

training_args = TrainingArguments(
  # training arguments...
)

# A lot of code here

# Initialize our Trainer
trainer = Trainer(
    model=model,
    args=training_args,  # Original training arguments.
    train_dataset=train_dataset if training_args.do_train else None,
    eval_dataset=eval_dataset if training_args.do_eval else None,
    compute_metrics=compute_metrics,
    tokenizer=tokenizer,
    data_collator=data_collator,
)

Inference

You can compile and export your 🤗 Transformers models to a serialized format before inference on Neuron devices:

bash

optimum-cli export neuron \
  --model distilbert-base-uncased-finetuned-sst-2-english \
  --batch_size 1 \
  --sequence_length 32 \
  --auto_cast matmul \
  --auto_cast_type bf16 \
  distilbert_base_uncased_finetuned_sst2_english_neuron/

The command above will export distilbert-base-uncased-finetuned-sst-2-english with static shapes: batch_size=1 and sequence_length=32, and cast all matmul operations from FP32 to BF16. Check out the exporter guide for more compilation options.

Then you can run the exported Neuron model on Neuron devices with NeuronModelForXXX classes which are similar to AutoModelForXXX classes in 🤗 Transformers:

diff

from transformers import AutoTokenizer
-from transformers import AutoModelForSequenceClassification
+from optimum.neuron import NeuronModelForSequenceClassification

# PyTorch checkpoint
-model = AutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased-finetuned-sst-2-english")
+model = NeuronModelForSequenceClassification.from_pretrained("distilbert_base_uncased_finetuned_sst2_english_neuron")

tokenizer = AutoTokenizer.from_pretrained("distilbert-base-uncased-finetuned-sst-2-english")
inputs = tokenizer("Hamilton is considered to be the best musical of past years.", return_tensors="pt")

logits = model(**inputs).logits
print(model.config.id2label[logits.argmax().item()])
# 'POSITIVE'
