实例化driver报错：more than one device/emulator;Code '1'

老师，我连接了2台模拟器，实例化driver的时候执行到webdriver.remote那边就报错adb:error:more than one device/emulator;Code '1’
base_driver.py

from appium import webdriver
from util.write_user_command import WriteUserCommand

class BaseDriver:
    def android_driver(self,i):
        write_file=WriteUserCommand()
        device=write_file.get_value('user_info_'+str(i),'deviceName')
        print('device:'+device)
        port=write_file.get_value('user_info_'+str(i),'p')
        print('port:'+port)
        desired_caps = {

        }
        # 连接appium server
        print(port)
        url='http://127.0.0.1:%s/wd/hub'%port
        print(url)
        driver = webdriver.Remote(url, desired_caps)
        print('error before driver.remote')
        return driver

报错：

selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Error executing adbExec. Original error: 'Command '/Users/zy/android-sdk-macosx/platform-tools/adb -P 5037 -s 192.168.56.106\:5555 forward tcp\:8200 tcp\:6790' exited with code 1'; Stderr: 'adb: error: more than one device/emulator'; Code: '1'

我看了下，程序执行到webdriver.remote()就报错了，然后我输出了一下url，确认是两个端口号不一样到url。
后来我用客户端，一样的配置，2台模拟器，连接了一下appium，也是报more than one device错误，日志如下：

然后我连接2台真机试了下，也是报这个错误。
老师，我的appium版本是1.15.1的，不能同时连接多个设备吗

老师我的问题没解决，同样的报错?。我后来手动打开2个appium服务，写代码用多线程去做启动配置，还是同样的adb报错

    你再cmd去运行，你启动appium用多线程，但是case执行driver初始化用多进程

    老师谢谢你的解答，我已经把你的多线程课程这部分内容看完，事实上我一开始执行的是按照你的课程讲解一样的代码执行，可惜报错，我就怀疑是否是因为python2.7和python3.X在多线程这块的差异导致的，于是我去掉了循环实例化线程，改为一个一个实例化线程，还是报错more than one device.后来我找别的同事在他电脑上执行了我的代码，他那边是可以的，所以可能是我的环境关系。老师的课程讲得非常清楚，谢谢老师！
