我想创建自己的健身房环境。我已按照此处解释的步骤进行操作： https: //github.com/openai/gym/blob/master/docs/creating-environments.md。根据他们的建议，我创建了环境（链接：https://drive.google.com/open? id=1RmcSBZYKCARaNsdlOsACrk9ls8snqxlj ）。安装并运行后，将创建环境并显示打印输出“已创建，步骤”。但是，当我再次按下“运行”按钮（spyder ide：python3.7）时，它向我显示“错误：无法重新注册 id：foo-v0”。如果我按“重新启动内核”按钮，问题将暂时消失。但再次“运行”会显示相同的错误。请帮我解决这个问题。

我试图将图像文件从一台PC(客户端)发送到运行MATLAB的另一台PC(服务器),输出图像为空.

从另一个讨论中,我了解到主要问题是Java和MATLAB之间存在一些"图像矩阵不匹配".但是,我并不完全理解这个问题.

如果你能给我一些建议,我将不胜感激.

客户端Java代码:

import java.awt.image.BufferedImage;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.IOException;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;

import javax.imageio.ImageIO;

public class myclientimage 
{
    public static void main(String args[]) throws IOException
    {
         BufferedImage img = ImageIO.read(new File("D:\\zzz.jpg"));
         ByteArrayOutputStream baos = new ByteArrayOutputStream();        
         ImageIO.write(img, "jpg", baos);
         baos.flush();
         byte[] buffer = baos.toByteArray();

         DatagramSocket clientSocket = new DatagramSocket();       
         InetAddress IPAddress = InetAddress.getByName("192.168.0.102");
         System.out.println(buffer.length);

         DatagramPacket packet = new DatagramPacket(buffer, buffer.length, IPAddress, 9091);

         clientSocket.send(packet);

         System.out.println("aaaa");
    }

}

服务器MATLAB代码:

udpA=udp('192.168.0.104', 9090,'LocalPort', 9091);
fopen(udpA);
A = fread(udpA, …
