Setting up an open-source environment can be a bit tricky. You'll need robust hardware with plenty of memory and possibly a GPU to run some of these models.

Not all open-source models can match the capabilities of more polished products like ChatGPT, which benefits from a large team of engineers. This is because open-source models are still improving.

If you're planning to use an open-source model commercially, not all of them are suitable for that purpose.

Here are some potential challenges you might face with open-source models:

  • They might require robust hardware: plenty of memory and possibly a GPU
  • They typically don’t match the capabilities of more polished products
  • Not all models can be used commercially

Keep in mind that the gap between open and closed-source models is narrowing, but there are still some limitations to consider.

Setting Up Environment

To set up your offline environment, you need to consider your available disk space, as you'll need to allocate sufficient space to accommodate the size of the models you plan to work with.

Installing the Hugging Face Transformers library and downloading pre-trained models is just the beginning, as you also need to ensure compatibility with your hardware and operating system.

You should also think about your RAM capacity, as it will affect the performance of your offline environment.

Staying up-to-date with Hugging Face updates and new releases is crucial, as they often introduce improvements, bug fixes, or new features that enhance the offline experience.

Using models offline is a great way to perform various NLP tasks without internet connectivity. You can load pre-trained models locally to undertake tasks such as tokenization, input processing, and generating predictions.

By loading models offline, you can customize model behavior according to specific requirements. For instance, you can fine-tune parameters like temperature or employ advanced sampling techniques like top-k sampling to tailor the model's output to your needs. This flexibility enables you to fine-tune model behavior based on the nuances of your data or the intricacies of your task.

You can use Hugging Face's pre-trained Python models for NLP tasks, such as question answering and token classification, and integrate them into a production Java environment using the Deep Java Library (DJL). DJL provides an easy-to-use model-loading API designed for Java developers, allowing you to access model artifacts from various sources, including the pre-loaded model zoo, HDFS, S3 buckets, and your local file system.

DJL also simplifies data processing to implement Hugging Face models by bundling tokenizer and vocabulary tools required for implementation. This enables you to bring your own question answering model using the Hugging Face toolkit in just 10 minutes.

Here's a summary of the steps to preprocess the data with Ray Data:

• Instantiate your tokenizer with the AutoTokenizer.from_pretrained method to get a tokenizer that corresponds to the model architecture you want to use and download the vocabulary used when pretraining this specific checkpoint.

• Pass use_fast=True to the preceding call to use one of the fast tokenizers, backed by Rust, from the HF Tokenizers library.

• Use the built-in from_huggingface() function to convert the dataset to Ray Data.

• Write a function that preprocesses the samples by feeding them to the tokenizer with the argument truncation=True.

To load your own model from the local file system, you can construct the Criteria API, which is used as search criteria to look for a ZooModel. In this application, the directory of the local TorchScript model will be specified, so that the ZooModel will be loaded accordingly, with .optModelPath().

Implement Bert Translator

Implementing the BertTranslator is a crucial step in creating your own translator. This involves combining the preprocess and post-process steps that were previously discussed.

You can combine the preprocess and post-process together to create your own translator BertTranslator. It will be used in constructing the Criteria and the predictor.

With DJL, you can transform images into N-dimensional arrays with just one line of code, making it much faster than implementing it from scratch. This is a huge time-saver and a major advantage of using DJL.

The model-loading API provided by DJL is designed for Java developers, making it easy to access model artifacts from various sources, including a pre-loaded model zoo, HDFS, S3 buckets, and your local file system.

Model Optimization

ONNX Runtime offers offline optimizations in its tools folder, supporting most classical transformer architectures, including miniLM. You can run these optimizations through the command line.

By performing optimizations in Python code, you can have a single command to execute. This can be useful for convenience. A part of the performance improvement comes from approximations performed at the CUDA level on the activation layer (GELU) and attention mask layer.

These approximations can have a small impact on model outputs, but in my experience, it has less effect on model accuracy than using a different seed during training.

Tuning Hyperparameters with Ray Tune

Ray Tune is a powerful tool for tuning hyperparameters in your model. You can pass your TorchTrainer into a Tuner and define the search space to get started.

To use Ray Tune, you need to define the search space for the hyperparameters you want to tune. This can include things like learning rate, epochs, and other parameters.

The example in the article shows how to use an ASHAScheduler to aggressively terminate underperforming trials. This means that if a trial is not performing well, it will be terminated quickly to free up resources for other trials.

Here are some key statistics from the example:

The best result from the tuning run is a loss of 0.6160, with a learning rate of 0.000150 and an epoch of 0.25.

Optimizations

Optimizations can significantly improve model performance.

ONNX Runtime offers offline optimizations in its tools folder, supporting most classical transformer architectures, including miniLM.

You can run these optimizations through the command line or integrate them into Python code for a single execution command.

Enabling all possible optimizations and converting to float 16 precision can yield a performance improvement.

Approximations at the CUDA level, such as those on the activation layer (GELU) and attention mask layer, can have a small impact on model outputs but less so than using a different seed during training.

TensorRT doesn't have offline optimizations, but performing symbolic shape inference on the vanilla ONNX model is recommended.

This step can prevent TensorRT from losing tensor shape information due to the model being split into subgraphs.
