add support for building windows/arm64 package #644

niyas-sait · 2022-03-28T09:20:30Z

This patch adds support for building windows/arm64 python package.

Python binary wheels can be created successfully with python setup.py bdist_wheel and passes all tests.

CI failures look unrelated to this patch. Any idea?

asenyaev · 2022-04-01T07:52:39Z

Hi, @nsait-linaro!

It was a network issue on a runner. I've restarted jobs.

In addition, I'm going to test your changes on ARM Windows.

Thanks. Looks like passing now ! Can this be merged please ?

asmorkalov · 2022-04-06T05:27:21Z

asenyaev is working on ARM Windows setup right now to check the new platform. We will merge the patch soon, if it works well on our side too.

Hi @nsait-linaro!

I've tried to build opencv-python package on a Virtual Machine with Windows ARM with your changes, and a wheel was built as amd64 package.

In addition, Visual Studio docs said:

"Visual Studio is built to target processors based on the x64 architecture, and there are no versions of Visual Studio for ARM-based processors."
"For the best experience, we recommend you use Visual Studio on a separate, x64 powered, computer, and use the remote deployment and debugging features in Visual Studio to target the ARM-based device."

Could you tell me please, what is your workaround?

Visual Studio doesn't yet have native ARM64 toolchain but that is okay as we can run in emulation and target ARM64. You will need to install few ARM64 specific components in visual studio. I have used the following but other versions probably would work as well.

C++ Universal Windows Platform support for v142 build tools (ARM64)
MSVC v142 - VS 2019 C++ x64/x86 build tools (latest)
MSVC v142 - VS 2019 C++ ARM64 build tools (latest)
MSVC v142 - VS 2019 C++ ARM64 Spectre-mitigated libs (latest)
C++ ATL for latest v142 build tools (ARM64)
C++ ATL for latest v142 build tools with Spectre Mitigations (ARM64)
Windows 10 SDK (10.0.19041.0)
Workload: Desktop development with C++ (this is essential to get a working env with vcvarsall)

Also just make sure you are using a Python (Arm64) rather than Amd64 version. Otherwise, it will generate AMD64 wheels.
Pre-built binaries are available on python.org and NuGet. Please check this link

I've also faced an issue with building cmake package (there are no wheels for windows arm in PyPi), it crashes immediately. How did you solve it?

Did you try pip install cmake ? I used an emulated cmake - Try this

Yes, I tried it, it has been broken. Thanks for the suggestion, it works and a build started. I'll let you know the result when the build is complete.

asenyaev · 2022-04-07T17:05:12Z

@nsait-linaro, it's finally was built successfully!

Thank you for the contribution and support!

No worries ! Thanks for trying out the patch

I want to summarize the current status how to build opencv-python package on Windows ARM. You need to follow steps:

Firstly, install python for Windows ARM. At the moment, there are no released python installers, but worked pre-release exist (link).
Install an emulated cmake (link). Currently, you cannot install cmake with pip, there are no pre-built wheel and the build from source fails.
Install Visual Studio Build Tools 2019 marking "Individual Components":

C++ Universal Windows Platform support for v142 build tools (ARM64)
MSVC v142 - VS 2019 C++ x64/x86 build tools (latest)
MSVC v142 - VS 2019 C++ ARM64 build tools (latest)
MSVC v142 - VS 2019 C++ ARM64 Spectre-mitigated libs (latest)
C++ ATL for latest v142 build tools (ARM64)
C++ ATL for latest v142 build tools with Spectre Mitigations (ARM64)
Windows 10 SDK (10.0.19041.0)

Build opencv-python package using following command:

pip wheel . --verbose

Finally, you should have a opencv-python wheel

If you need install OpenCV python package with opencv_contrib or without UI, you have to define environment variables (check it here)

Thanks a lot to @nsait-linaro!

I tried these steps and finally on the "pip wheel . --verbose" step, its failing -
