# Summary The goal of this PR is to add a doc page to list a number of environment that effect the PyTorch runtime. It will likely not be exhaustive but hopefully will be added and updated to stay relevant.

Torch Environment Variables
|
|
===============================
|
|
|
|
PyTorch leverages environment variables for adjusting various settings that influence its runtime behavior.
|
|
These variables offer control over key functionalities, such as displaying the C++ stack trace upon encountering errors, synchronizing the execution of CUDA kernels,
|
|
specifying the number of threads for parallel processing tasks and many more.
|
|
|
|
Moreover, PyTorch leverages several high-performance libraries, such as MKL and cuDNN,
|
|
which also utilize environment variables to modify their functionality.
|
|
This interplay of settings allows for a highly customizable development environment that can be
|
|
optimized for efficiency, debugging, and computational resource management.
|
|
|
|
Please note that while this documentation covers a broad spectrum of environment variables relevant to PyTorch and its associated libraries, it is not exhaustive.
|
|
