path is valid before Push-Location runs: either add a preceding Model Optimizer
clone step targeting that location or explicitly instruct users to set the
variable to their existing checkout path, and ensure the subsequent commands use
the validated location.
- Around line 65-66: Update the Windows ARM64 setup instructions so the LlvmRoot

add the missing LLVM installation/extraction step into $Venv\llvm-arm64 or point
LlvmRoot to the actual installed path, ensuring the later clang-cl.exe checks

- Around line 3-4: Update the installation block to match the smoke-test

PyPI cupy-cuda13x 14.2.0 files Windows ARM64 win_arm64 and onnxruntime TensorRT RTX EP package 0.4.0 import onnxruntime_ep_nv_tensorrt_rtx
💡 Result:
For the requested packages and libraries, here is the current status as of August 27, 2026: CuPy Windows ARM64 Support CuPy version 14.2.0 is available on PyPI [1][2]. Official documentation and package listings specify that CuPy wheels (precompiled binaries) for Windows are currently tested and provided primarily for x86_64 architectures [3][4]. While CuPy provides broader support for aarch64 on Linux, there is no official support or precompiled win_arm64 wheel for CuPy on Windows in the PyPI release [3][4][5]. Users requiring CuPy on Windows ARM64 would likely need to build from source, which is not natively supported by the standard binary distribution process [3]. ONNX Runtime TensorRT RTX EP 0.4.0 The package onnxruntime-ep-nv-tensorrt-rtx version 0.4.0 is available as a meta-package on PyPI [6]. This package is designed to support the NVIDIA TensorRT RTX Execution Provider (EP) via the ORT Plugin EP ABI [7][8]. Importing the EP To use the TensorRT RTX EP in your Python code, you import the provider library and register it with ONNX Runtime [7][9]. The import statement and registration pattern is as follows: import onnxruntime as ort import onnxruntime_ep_nv_tensorrt_rtx as trt_ep # Register the EP plugin ort.register_execution_provider_library(trt_ep.get_ep_name, trt_ep.get_library_path) The onnxruntime_ep_nv_tensorrt_rtx module provides utility functions like get_ep_name() and get_library_path() to handle the registration of the plugin DLL (onnxruntime_providers_nv_tensorrt_rtx.dll) [7][9]. Note that this EP requires an NVIDIA RTX GPU (Ampere architecture or later) and appropriate driver support [7][10]. The meta-package onnxruntime-ep-nv-tensorrt-rtx automatically pulls in the required CUDA-specific variant (e.g., onnxruntime-ep-nv-tensorrt-rtx-cu13) [6].

Align the installation block with the smoke-test dependencies.
pip install -e ".[onnx]" installs onnxruntime-gpu==1.22.0 and cupy-cuda12x on Windows, but the smoke test requires the documented ONNX Runtime 1.24.4, TensorRT RTX EP module, and cupy-cuda13x 14.2.0. The TensorRT RTX package is not declared, and CuPy 14.2.0 has no Windows ARM64 wheel. Document the tested package versions and a supported CuPy ARM64 source-build process; otherwise setup can fail before PyArrow validation.

The setup defines $LlvmRoot as $Venv\llvm-arm64, but no command installs or extracts LLVM into that directory. The later compiler checks and CMake commands can therefore fail because $LlvmRoot\bin\clang-cl.exe does not exist. Add the LLVM installation step or set $LlvmRoot to the actual installation path.

There was a problem hiding this comment.
I suggest we dont tie documentation with 1 SKU unless absolutely needed. We can focus on ModelOpt for WoA in general.
There was a problem hiding this comment.
I want to support py 3.13 so the modelopt-onnx and modelopt-torch can be in the same env, can you give me a check list? Like what need to be checked in py 3.13 env.
Also, what do you think of also supporting py 3.14
There was a problem hiding this comment.
For the checklist, I think it would be better to get this details based on actual run / setup.
For the documentation, we have support matrices in documentation, where we can mention what is supported / validated today.
We can have py 3.14 support in follow up, after some validation.

Wire the ABI backend before documenting this command. The NvTensorRtRtx path only checks for DLLs, passes NvTensorRTRTXExecutionProvider to ort.InferenceSession, and never calls ort.register_execution_provider_library. The quantization CLI also does not define --trt_rtx_backend. Import the ABI package and register its library before calibration, or remove this option and claim.

Separate the ARM64 requirements from the general Windows rows.
Adding ARM64 to the architecture row makes the existing requirements appear to apply to ARM64, but the linked ARM64 guide installs onnxruntime>=1.24.2 and documents only a CPython 3.13, cp313-cp313-win_arm64 build path. This table still lists ONNX Runtime 1.20.0 and Python >=3.10,<3.14 without an ARM64 qualifier. Split or qualify the rows so users do not follow a different dependency contract from the ARM64 guide.

Fail fast when setup or validation commands fail.
The wheel installation, smoke test, and pip check can return non-zero, but the guide does not inspect $LASTEXITCODE. A pasted PowerShell block can therefore continue after a failed installation or validation.

This directory is reserved for Python 3.13 ARM64-specific example assets if
they are needed in the future.
Lets not make this directory upfront. We have installation guide and ONNX PTQ example at its own places. I don't see this directory serving any purpose. I would prefer avoiding arch specific example folder unless absolutely needed (like different scripts for different archs - which normally doesn't happen).

It would be better to elaborate a bit about the issue (1-2 liners).

Summarizing few corrections needed as per current PR:
- Removing python_313_arm64 directory (unless absolutely needed in real).
- Minor nit picks, rewording I highlighted earlier.
Otherwise, change looks okay to me.

Limit the Windows on Arm support claim.
The support matrix documents parity for the ONNX quantization formats, not every Windows x64 feature. It also qualifies ARM64 support as experimental and dependent on native ARM64 packages and execution providers. Please use that scope and correct the grammar (supports the same ... as and refer to the).
Proposed wording
-WoA support the same feature as Windows x64, please refer the [Support Matrix](https://nvidia.github.io/Model-Optimizer/guides/0_support_matrix.html#support-matrix)+WoA support is experimental and targets the same ONNX quantization formats as Windows x64. Availability depends on native ARM64 packages and execution providers; see the [Support Matrix](https://nvidia.github.io/Model-Optimizer/guides/0_support_matrix.html#support-matrix).📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
