实时读取服务器的终端输出(Real-time reading of terminal output from server)

 我试图在我的服务器上处理来自相机的图像，并在本地计算机上实时处理后获取信息。 我可以在我的服务器上获取必要的信息作为终端输出，但是我不能把这些信息放到本地机器上的python代码中，直到我的服务器程序运行。 我试过这段代码： 
 
cmd="sshpass -p 'pass' ssh -Y user@ip -t 'process_image; bash -l'"
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1)
for line in iter(p.stdout.readline, b''):
    print(line)
    p.stdout.close()
    p.wait()
 
 但它不起作用 - 看起来这个代码只是暂停了我的程序。 我试图将输出写入文件并从本地机器读取文件，但它会扭曲我的数据。 我能做些什么来实时读取服务器的终端输出？ 

I'm trying to process images from my camera on my server and get the information after processing on my local machine in real-time. I can get necessary information as terminal outputs on my server, but I can't put this info in my python code on local machine, until my server program is running. I'm tried this code:
 
cmd="sshpass -p 'pass' ssh -Y user@ip -t 'process_image; bash -l'"
p = subprocess.Popen(cmd, stdout=subprocess.PIPE, bufsize=1)
for line in iter(p.stdout.readline, b''):
    print(line)
    p.stdout.close()
    p.wait()
 
But it doesn't work - it looks like this code just paused my program. I tried to write output to file and than read file from local machine, but it distorts my data. What can i do to read terminal output from server in real-time?
