This project is just some PyQt examples

https://pypi.org/project/PyQt5/#files
As you can see, There is no precompiled package for this platform.
You can add Debian's third-party source and install it through apt command

[Irony]

Or you can install QT first and then compile the corresponding version of pyqt5 yourself

[Bogdan Hlevca]

Thanks, it was useful. I installed with apt and then I removed pyqt5 from the list of required packages so that pip3 does not crash.

[Liviu Ionescu]

There is no precompiled package for this platform.

Would it be possible to add precompiled packages for aarch64?

[Bogdan Hlevca]

The solution I proposed above for the aarch64 packages that have a pyqt5 dependency with pip is a temporary hack.

The real solution is to add PyQt5-5.15.6-cp36-abi3-manylinux1_aarch64.whl at https://pypi.org/project/PyQt5/#files

[Irony]

Because riverbankcomputing didn't provide arm package.

solutions:

1. Configure official source or third-party source, and use apt or yum to install.
2. Install Qt first, then build PyQt5 from source

[Bogdan Hlevca]

Thanks, but that's a hack and we already have a solution by installing with apt and no compilation from source is needed. The idea is to have an elegant solution for all pip packages with pyqt5 requirements.

I already filed a bug report with Riverbank Computing asking to provide an aarch64 whl file in the pypi repository.
