The speaker explains the conversion process, including converting PyTorch models to ONNX and then to TensorRT or OpenVINO, and cautions against using TensorFlow PB file and Cafe. The speaker also discusses the importance of setting the floating point format properly and recommends using FP 32 for most models. The video provides examples of model conversion and encourages viewers to visit the official website for more educational videos.

  • 00:00:00 In this section, the speaker discusses the different AI frameworks, including PyTorch, TensorFlow, Keras, and Cafe, and explains their company's preferred method of using PyTorch to save the model as an ONNX file, which they double-check with their data set using ONNX Runtime. If the test is passed, they convert the ONNX model to TensorRT and OpenVINO formats. The speaker cautions against using TensorFlow PB file and Cafe and recommends using Python with original data and PyTorch for training instead. Lastly, the speaker mentions that sometimes the inference engines need the floating point to be set properly.

  • 00:05:00 In this section, the speaker discusses how the choice of floating point format affects the speed and precision of model conversion. He explains that while using FP 16 can increase speed, it can lead to less precision, while using FP 64 results in slower speed but higher precision. The speaker recommends using FP 32 for most models and discusses how different formats can be used for specific types of data sets, like FP 32 and FP 64 for medical image analysis. He also explains that converting a model from FP 32 to FP 16 can lead to precision loss, which can be mitigated by using calibration, deletion or retraining with FP 16 to improve the model's precision.

  • 00:10:00 In this section of the video, the speaker discusses the trade-offs between speed, precision, and data information when using different AI frameworks such as PyTorch, TensorFlow, Keras, ONNX, TensorRT, and OpenVINO.

v1.12.0 ONNX Runtime - Release Review



v1.12.0 ONNX Runtime - Release Review

The v1.12.0 release of the ONNX Runtime (ORT) focuses on inferencing but also includes continued investments in training, with integration with Hugging Face Optimum resulting in the acceleration of several Hugging Face models. New features include the ability to use native ORT ops in custom ops and call directly into a native or runtime operator without building a graph. The release also includes support for .NET 6 and the Multi-platform App UI (MAUI) and execution providers for specific platforms like the Neural Processing Unit on Android and Core ML on iOS. Performance improvements were made by reducing memory allocations during inferencing and eliminating unnecessary logging. Future improvements to enhance cache locality and thread pool utilization are planned.

  • 00:00:00 In this section, the new features and updates of version 1.12 of ONNX Runtime are discussed. These include the deprecation of .net standard 1.1 support and the addition of support for ONNX offset 17 and on on xml offset 3. One new feature is the capability to invoke individual ops without creating a separate graph, and support for feeding external initializers for inferencing was also added. Other updates include support for python 310 and enabling mac m1 support in the python and java libraries, as well as adding .net 6 maui support in the c-sharp package. improvements to performance and quantization were also made, and new execution providers were introduced, including Qualcomm Snappy and general infrastructure for the accident pack ep, with ongoing work to add more kernels for mobile and web scenarios.

  • 00:05:00 In this section, the speaker discusses the updates made to the ONNX Runtime (ORT) and mentions that the focus has been primarily on inferencing. However, there have been continued investments in ORT training to accelerate the training of large models. The recent integration with Hugging Face Optimum has resulted in the acceleration of several Hugging Face models. The speaker then introduces Randy, who discusses a new feature that allows users to use native ONNX Runtime ops in custom ops. Randy explains that this feature came about from customer requests to make custom operators more performant and versatile by utilizing the powerful matrix computation capabilities of the ONNX Runtime.

  • 00:10:00 In this section, the speaker discusses a new feature that allows customers to call directly into a native or runtime operator without building a graph or something similar, making it much easier to execute matrix computation functions. This feature was proposed to the community because another group of customers were working on audio processing and wanted to achieve statement management, meaning they wanted to cache some past inputs or outputs, combine them with the latest input, and feed the operator with a combined altered input. This was previously difficult to achieve, but with the new feature, customers can add a wrapper around the native operator of the ONNX Runtime to do the statement management, making their lives easier and achieving their purpose. Samples of how to use this feature are available on the community website.

  • 00:15:00 In this section, Scott McKay, the lead for ONNX Runtime Mobile, discusses the new features added in v1.12.0 of ONNX Runtime.
