在 android studio 中使用 chaquopy 时如何解决 Python.getInstance() 错误

Question

我正在尝试在 android studio 中使用 chaquopy 来识别视频中的音频并将其转换为文本，但是当我调用 Python.getInstance() 时，它会用红色覆盖它。可能是什么问题？

build.gradle(应用程序)

plugins {
    id 'com.google.gms.google-services'

    //for chaquopy(python)
    id 'com.android.application'
    id 'com.chaquo.python'
}


android {
    compileSdk 31

    defaultConfig {
        applicationId "com.talhakara.uzaktanegitimbitirmeprojesi"
        minSdk 16
        targetSdk 30
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
       // for chaquopy(python)
        ndk {
            abiFilters "armeabi-v7a", "arm64-v8a", "x86", "x86_64"
        }
        python {
            buildPython "C:/Users/enest/AppData/Local/Programs/Python/Python39/python.exe"

        }

        sourceSets {
            main {
                python.srcDir "src/main/python"
            }
        }
        //
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildFeatures {
        viewBinding true
        dataBinding true
    }
}

        //start python

        });

会不会是gradle版本的问题？因为我的 gradle 版本 7.0.4 在 chaquopy 的文档中显示 7.0 是最新的。它会导致这个问题吗？我使用 10.0.1 作为 chaquopy 版本，因为 android studio 推荐它作为最新版本。如果这些有问题，我应该使用哪个版本？

正确的语法只是 Python.getInstance()，而不是 new Python.getInstance()。
