restart jtop client -> BrokenPipeError: [Errno 32] Broken pipe

[jeronimoagullo]

This issue is related to the issue #261

I have the following code in python 3.10 with jtop 4.3.0:

import jtop

jetson = None

while True:
    try:
        if jetson is None:
            print("Initializing jtop client...")
            jetson = jtop.jtop()
            jetson.start()

        while jetson.ok():

            # Temperature
            temperatures = jetson.temperature
            temp_cpu = temperatures['cpu']['temp']
            temp_gpu = temperatures['gpu']['temp']
            print(f"Temperature CPU: {temp_cpu}ºC and GPU: {temp_gpu}ºC")

    except jtop.JtopException as e:
        print(f"Jtop error: {e}")
    except Exception as e:
        print(f"Error getting metrics: {e}")
    finally:
        try:
            jetson.close()  # Ensure the client is closed
        except Exception as close_error:
            print(f"Error while closing jtop client: {close_error}")
        jetson = None # Reset the reference                

It works correctly until I stop and start again the jtop.service with systemctl command. I know from issue #261 that the jtop client must be restarted so that the SyncManager is restarted. However, I cannot get it working once the jtop service restarts.

Are I missing something? What should be the correct approach to restart jtop client?
Thanks

Hi @jeronimoagullo
I never tried this case, I'll take a look to find a nice way to connect again to jtop
