PyTorch 1.8.1 comes with PyTorch Profiler

by Emma


The latest version of the machine learning library PyTorch is now available. PyTorch 1.8.1 introduces the PyTorch Profiler, which is a tool for performance analysis and troubleshooting for large-scale deep learning models. 

According to PyTorch’s team, there was a lack of available tools for such a task, and the tools that did exist missed out on important PyTorch-specific information. Machine learning scientists ended up needing to use a combination of tools or manually adding correlation information in order to meet their needs. 

PyTorch Profiler collects both GPU hardware and PyTorch information, correlates them, performs detection of model bottlenecks, and generates recommendations on how to ease those bottlenecks. The information is visualized in TensorBoard so the user can easily see it.

In addition, the new Profiler API is natively supported in PyTorch, which means users don’t need to install additional packages in order to make use of the tool. 

Other new improvements in PyTorch 1.8.1 include enabling autocast for PyTorch xla, making the torch. submodule import more autocomplete-friendly, and more.
