PyTorch 1.9 has arrived: this is what you need to know – Texasnewstoday.com

PyTorch, a Facebook-backed open source library for the Python programming language, has reached version 1.9 and has made significant improvements in scientific computing.

PyTorch has become one of the more important Python libraries for people working in data science and AI. Microsoft recently added enterprise support for PyTorch deep learning on Azure. PyTorch has also become the standard for Facebooks AI workloads.

Googles TensorFlow and PyTorch are integrated with important Python add-ons such as NumPy and data science tasks that require faster GPU processing.

According to the release notes, the PyTorch linear algebra module torch.linalg will move to stable in version 1.9, providing NumPy users with familiar add-ons for working with math.

According to these release notes, this module extends PyTorch support and implements all the functions of NumPys linear algebra module (currently supporting accelerators and autograd). torch.linalg.matrix_norm And torch.linalg.householder_product..

Also moving to the stable version is the Complex Autograd feature, which provides users with a way to calculate complex gradients and use complex variables to optimize real-valued loss functions.

This is a feature needed by multiple prospective users of PyTorch complex numbers, such as TorchAudio, ESPNet, Asteroid, and FastMRI, now and downstream, said the PyTorch project.

This release also has some debugging features with the new torch.use_determinstic_algorithms option. When enabled, the operation works deterministically if possible. If not enabled, you will get a runtime error if it can behave non-deterministically.

There is a new beta version of torch.special Module Similar to SciPys special module. This brings many features that are useful for scientific computing and working with distributions such as: iv, ive, erfcx, logerfc,and logerfcx..

And this version brings a PyTorch Mobile interpreter designed to run programs on edge devices. This is a streamlined version of the PyTorch runtime. This significantly reduces the binary size compared to the runtime on the current device.

The current pt size on Arm64-v8a Android MobileNet V2 is 8.6MB compressed and 17.8MB uncompressed. We are using MobileInterpreter to target compressed sizes less than 4MB and uncompressed sizes less than 8MB, said the PyTorch project. Says.

Mobile app developers can also use the TorchVision library with iOS and Android apps. The library contains C ++ TorchVision operations that assist with tasks such as object detection and segmentation in video and images.

There are some additional features that are useful for distributed training of machine learning algorithms. TorchElastic, which is currently in beta, is part of the core PyTorch and is used to handle scaling events properly.

There is also CUDA support for RPC. CUDA RPC sends Tensors from local CUDA memory to remote CUDA memory for more efficient peer-to-peer Tensor communication.

In terms of performance, this version of PyTorch also offers a stable release of the Freezing Application Protocol Interface (API), a beta version of PyTorch Profiler, a beta version of the inference mode API, and a beta version of torch.package in new ways. .. Package the PyTorch model.
