The current version of Chaquopy defaults to Python 3.8, but we don't have NumPy 1.23.3 for that version of Python.

• To see which NumPy versions are available for which Python versions, see the repository.
• To change your app's Python version, see the documentation.

May I know which version of NumPy supported by Chaquopy? I saw this version the link that you have referred, so I think this NumPy 1.23.3 is supported.

Update : I've tried to change my Python to 3.8 and install NumPy 1.20.3, but I still get an error

[mhsmith]

The "cp" part of the filename identifies the Python version. So the packages in that image are for Python 3.9.

[nathaniacalista01]

I've tried to downgrade my Python version and install the compatible version of numpy, but it still get an error

[mhsmith]

As you can see from the repository, NumPy 1.20.3 is available for Python 3.9, and NumPy 1.23.3 for Python 3.9-3.11.

If you still can't install it, please post thechaquopy section of your build.gradle file, and the full build log.

Yup I still get an error and for more context, I need to use numpy that is >= 1.20, therefore I use a higher version of Python (not 3.8). This is my chaquopy section

chaquopy {
    defaultConfig {
        version = "3.11"
        buildPython("C:/Users/ASUS/AppData/Local/Programs/Python/Python311/python.exe")
        pip{
            install("numpy==1.23.3")
            install("opencv-python")
            install("pupil_apriltags")
        }
    }
}

And now I don't get any error, but it is still loading until now (already 30 minutes)

[mhsmith]

Unfortunately we don't have OpenCV for Python 3.9 or later yet (#779). However, we do have a newer NumPy version for Python 3.8 in a separate repository: see https://github.com/chaquo/chaquopy/issues/559#issuecomment-989318791.

Thanks! it works like a charm for me
