I had to upgrade and re-install the OS on one of my Raspberry Pi’s. A script that I wrote now fails, and when I tried this example code (which i used as the basis for my Blynk control code), it fails with the same error. Example is here: [Blynk/nonBlockingBlynk.py at master · JemRF/Blynk · GitHub](https://github.com/JemRF/Blynk/blob/master/nonBlockingBlynk.py) When I run it, I get the following message: File “blynk\_python\_non\_blocking.py”, line 19, in BlynkLoop blynk.set\_user\_task(my\_user\_task, 1000) AttributeError: Blynk instance has no attribute ‘set\_user\_task’ Any ideas on how to fix this? ---

Just checked git hub. > Looks like they have removed the set\_user\_task function and you are supposed to use add\_user\_task. Haven’t looked at any code but it might just be change the name to see if it works ---

I had high hopes, but - no such luck: ``` blynk.add_user_task(my_user_task, 1000) ``` AttributeError: Blynk instance has no attribute ‘add\_user\_task’ ---

Check the docs – add\_user\_task takes between 3 and 5 parameters. ---

I believe this is the official github repository: > **[GitHub - vshymanskyy/blynk-library-python: Blynk library for Python.

Works with Python 2, Python 3, MicroPython. - GitHub - vshymanskyy/blynk-library-python: Blynk library for Python. Works with Python 2, Python 3, MicroPython. Looks like set\_user\_task was removed in February 2019. There are some example here that might point you in the right direction for how to modify your code to work with the latest version: > **[blynk-library-python/examples at master · vshymanskyy/blynk-library-python](https://github.com/vshymanskyy/blynk-library-python/tree/master/examples)** > > master/examples ---

> [@markn\_1](#): > > Check the docs – add\_user\_task takes between 3 and 5 parameters. I only see 2 that need to be specified: task, and second\_period. You don’t have to explicitly pass “self” (it’s bound to the instance) and there are defaults for initial\_state and authenticated. Can you just check the BlinkLib.py file you have to make sure you do have either add\_user\_task or set\_user\_task defined in there? ---

Thanks for all the help, but I finally gave up on that example. I don’t need to have Blynk running periodic tasks, so I just put Blynk.run() in a thread with a sleep time of 1 second, and that worked. ---

I’m going to blame the switch to the new platform for the dispiriting lack of appropriate responses to my brilliant setup. I expect much better performance next time someone quotes Monty Python. C’mon people! Get it together! ---
