Question

我试图在Google Compute Engine VM上运行CartPole-v0示例。 https://gym.openai.com/docs

package com.example.contentprovider;

import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;
import android.database.MatrixCursor;
import android.provider.ContactsContract;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;


public class MainActivity extends AppCompatActivity {

// Cursor Adapter for storing contacts data
SimpleCursorAdapter adapter;

// List View Widget
ListView lvContacts;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Init ListView
    lvContacts = (ListView) findViewById(R.id.lvContacts);

    // Initialize Content Resolver object to work with content Provider
    ContentResolver cr = getContentResolver();

    // Read Contacts
    Cursor c = cr.query(ContactsContract.Contacts.CONTENT_URI,
            new String[] { ContactsContract.Contacts._ID,
                    ContactsContract.Contacts.DISPLAY_NAME }, null, null,
            null);


    // Attached with cursor with Adapter
    adapter = new SimpleCursorAdapter(this, R.layout.row, c,
            new String[] { ContactsContract.Contacts.DISPLAY_NAME },
            new int[] { R.id.lblName });

    // Display data in listview
    lvContacts.setAdapter(adapter);

}
}

我安装了XQuartz，ssh使用-X。

首先，我得到了 pyglet.canvas.xlib.NoSuchDisplayException：无法连接到＆＃34;无＆＃34;

然后根据http://www.gitterforum.com/discussion/openai-gym?page=28，我使用＆＃34; xvfb-run -s＆＃34; -screen 0 1400x900x24＆＃34; /斌/庆典＆＃34;

然后结果运行良好：

import gym
env = gym.make('CartPole-v0')
env.reset()
for _ in range(1000):
    env.render()
    env.step(env.action_space.sample()) # take a random action

但是没有任何渲染......
