Describe your issue

I installed torchvision by .whl but don't know why there is a problem says that failed to process, but it was installed successfully.
Because Chaquopy can not run native code and could not find torchvision== 0.18.1 so i use whl method

Windows wheels will not work on Android. The only Android wheels that are currently available for Torchvision are those in our repository. To use them, you'll need to change your Python version from 3.9 to 3.8.

In other words, replace your entire chaquopy block with this:

chaquopy {
    defaultConfig {
        buildPython("C:/Users/swchen7-c/Python39/Python.exe")
        version = "3.8"
        pip {
            options ("--extra-index-url", "https://pypi.tuna.tsinghua.edu.cn/simple/")
            install("torchvision")
            install("-r", "requirements.txt")
        }
    }
}

Our current latest torchvision version is 0.9.1. If you need a newer version, see #758.

Some of the other packages you attempted to install are unavailable, such as onnx (#216). Please search this issue tracker for more information on them.
