Deploy the Llama-2-13b mannequin with SageMaker Jumpstart

You’ll be able to select the mannequin card to view particulars concerning the mannequin corresponding to license, knowledge used to coach, and the best way to use it. You may as well discover two buttons, Deploy and Open pocket book, which aid you use the mannequin utilizing this no-code instance.

Once you select both button, a pop-up will present the Finish Person License Settlement and Acceptable Use Coverage (AUP) so that you can acknowledge.

After you acknowledge the insurance policies, you’ll be able to deploy the endpoint of the mannequin and use it through the steps within the subsequent part.

Deploy the Llama 2 Neuron mannequin through the Python SDK

Once you select Deploy and acknowledge the phrases, mannequin deployment will begin. Alternatively, you’ll be able to deploy by the instance pocket book by selecting Open pocket book. The instance pocket book supplies end-to-end steerage on the best way to deploy the mannequin for inference and clear up sources.

To deploy or fine-tune a mannequin on Trainium or AWS Inferentia cases, you first have to name PyTorch Neuron (torch-neuronx) to compile the mannequin right into a Neuron-specific graph, which can optimize it for Inferentia’s NeuronCores. Customers can instruct the compiler to optimize for lowest latency or highest throughput, relying on the aims of the applying. In JumpStart, we pre-compiled the Neuron graphs for quite a lot of configurations, to permit customers to sip compilation steps, enabling sooner fine-tuning and deploying fashions.

Observe that the Neuron pre-compiled graph is created primarily based on a particular model of the Neuron Compiler model.

There are two methods to deploy LIama 2 on AWS Inferentia-based cases. The primary methodology makes use of the pre-built configuration, and permits you to deploy the mannequin in simply two traces of code. Within the second, you will have higher management over the configuration. Let’s begin with the primary methodology, with the pre-built configuration, and use the pre-trained Llama 2 13B Neuron Mannequin, for instance. The next code exhibits the best way to deploy Llama 13B with simply two traces:

from sagemaker.jumpstart.mannequin import JumpStartModel

model_id = "meta-textgenerationneuron-llama-2-13b"
mannequin = JumpStartModel(model_id=model_id)
pretrained_predictor = mannequin.deploy(accept_eula=False) ## To set 'accept_eula' to be True to deploy 

To carry out inference on these fashions, it is advisable to specify the argument accept_eula to be True as a part of the mannequin.deploy() name. Setting this argument to be true, acknowledges you will have learn and accepted the EULA of the mannequin. The EULA could be discovered within the mannequin card description or from the Meta web site.

The default occasion sort for Llama 2 13B is ml.inf2.8xlarge. You may as well attempt different supported fashions IDs:

  • meta-textgenerationneuron-llama-2-7b
  • meta-textgenerationneuron-llama-2-7b-f (chat mannequin)
  • meta-textgenerationneuron-llama-2-13b-f (chat mannequin)

Alternatively, if you’d like have extra management of the deployment configurations, corresponding to context size, tensor parallel diploma, and most rolling batch dimension, you’ll be able to modify them through environmental variables, as demonstrated on this part. The underlying Deep Studying Container (DLC) of the deployment is the Giant Mannequin Inference (LMI) NeuronX DLC. The environmental variables are as follows:

  • OPTION_N_POSITIONS – The utmost numbers of enter and output tokens. For instance, in the event you compile the mannequin with OPTION_N_POSITIONS as 512, then you should utilize an enter token of 128 (enter immediate dimension) with a most output token of 384 (the overall of the enter and output tokens needs to be 512). For the utmost output token, any worth beneath 384 is ok, however you’ll be able to’t transcend it (for instance, enter 256 and output 512).
  • OPTION_TENSOR_PARALLEL_DEGREE – The variety of NeuronCores to load the mannequin in AWS Inferentia cases.
  • OPTION_MAX_ROLLING_BATCH_SIZE – The utmost batch dimension for concurrent requests.
  • OPTION_DTYPE – The date sort to load the mannequin.

The compilation of Neuron graph relies on the context size (OPTION_N_POSITIONS), tensor parallel diploma (OPTION_TENSOR_PARALLEL_DEGREE), most batch dimension (OPTION_MAX_ROLLING_BATCH_SIZE), and knowledge sort (OPTION_DTYPE) to load the mannequin. SageMaker JumpStart has pre-compiled Neuron graphs for quite a lot of configurations for the previous parameters to keep away from runtime compilation. The configurations of pre-compiled graphs are listed within the following desk. So long as the environmental variables fall into one of many following classes, compilation of Neuron graphs will likely be skipped.
