 #. Create and activate a virtual environment: ::

 #. Install `PyTorch 2.5 <https://pytorch.org/get-started/locally/>`_ or later for CPU Usage. Install PyTorch 2.7 or later refer to `Getting Started on Intel GPU <https://pytorch.org/docs/main/notes/get_start_xpu.html>`_ for XPU usage.

 #. Here is an example of how to use TorchInductor on Windows:
-.. code-block:: python
-
-    import torch
-    device="cpu" # or "xpu" for XPU
-    def foo(x, y):
-        a = torch.sin(x)
-        b = torch.cos(x)
-        return a + b
-    opt_foo1 = torch.compile(foo)
-    print(opt_foo1(torch.randn(10, 10).to(device), torch.randn(10, 10).to(device)))
