Проблема с запуском Chaquopy PythonConsoleActivity

Question

Я пытаюсь использовать python скриптов в android проекте (java). Моя конечная цель - запустить скрипты консоли face_recognition, поэтому я начал с демонстрации PythonConsoleActivity от Chaquopy. https://github.com/chaquo/chaquopy-console Я создал PythonActivity. java (который напоминает шаблон MainActivity. java из chaquopy)

package com.projectdevelopment.faces;

import android.app.*;
import com.projectdevelopment.faces.python.PythonConsoleActivity;

public class PythonActivity extends PythonConsoleActivity {

    @Override protected Class<? extends Task> getTaskClass() {
        return Task.class;
    }

    public static class Task extends PythonConsoleActivity.Task {
        public Task(Application app) {
            super(app);
        }

        @Override public void run() {
            py.getModule("main").callAttr("main");
        }
    }
}

У меня есть файл main.py, хранящийся в src / main / python по совету Chaquopy. Структура проекта

from six.moves import input


def main():
    print("Enter your name, or an empty line to exit.")
    while True:
        try:
            name = input()
        except EOFError:
            break
        if not name:
            break
        print("Hello {}!".format(name))

Я настроил проект gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        google()
        jcenter()
        maven { url "https://chaquo.com/maven" }

    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.0.0"
        classpath 'com.google.gms:google-services:4.3.3'
        classpath "com.chaquo.python:gradle:8.0.0"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

и приложение gradle

apply plugin: 'com.android.application'
apply plugin: 'com.chaquo.python'

android {
    compileSdkVersion 29

    defaultConfig {

        applicationId "com.projectdevelopment.faces"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"

        python{
            buildPython "C:/Python38/python.exe"

            //staticProxy "main.py"
            pip{
                install "six"
            }
        }
        ndk {
            abiFilters "armeabi-v7a", "x86", "arm64-v8a", "x86_64"
        }
        sourceSets{
            main{
                python{
                    srcDirs = ["src/main/python"]
                }
            }
        }

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

    testImplementation 'androidx.arch.core:core-testing:2.1.0'



}
apply plugin: 'com.google.gms.google-services'

Когда я запускаю приложение, я использую кнопку из mainActivity, чтобы запустить PythonActivity следующим образом:

 python.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent pythonActivity = new Intent(getApplicationContext(), PythonActivity.class);
                startActivity(pythonActivity);
            }
        });

При нажатии кнопки python возникает фатальное исключение: Невозможно создать экземпляр класса (см. ниже)

I/Process: Sending signal. PID: 4286 SIG: 9

Я уверен, что упускаю что-то простое, но я в растерянности. Я использую 64-битную версию Python3 .8.

Есть предложения?

Вы забыли включить содержимое src/main/python/chaquopy.
