ZeroMQ non blocking example error

[pwyq]

Hi,

I am trying to switch from Python Legacy Remote API to ZeroMQ as suggested, but I have encountered a bit more resistence than expected. One of the problems I would like to ask for help:

While I tried to run code from "simpleTest-nonBlocking.py" and with example scene "controlledViaZmq.ttt", I got the following error and I couldn't find a solution online.

Code: Select all

Program started
Traceback (most recent call last):
  File "/home/....../zeromq_nonblocking.py", line 92, in <module>
    asyncio.run(mainFunc())
  File "/home/....../lib/python3.9/asyncio/runners.py", line 44, in run
    return loop.run_until_complete(main)
  File "/home/....../lib/python3.9/asyncio/base_events.py", line 642, in run_until_complete
    return future.result()
  File "/home/....../zeromq_nonblocking.py", line 23, in mainFunc
    async with RemoteAPIClient() as client:
AttributeError: __aenter__

Could you provide some hints on how to resolve this issue? Thank you.

simpleTest-nonBlocking.py appears to work fine here (tested with Python 3.8 and 3.9).

Please post the content of /home/....../zeromq_nonblocking.py and provide additional details about your setup (OS, python version, ....).

I just renamed simpleTest-nonBlocking.py to zeromq_nonblocking.py and changed the import path of zmqRemoteApi for my own workspace. Nothing else.

OS: Ubuntu 18.04.6 LTS

Looks like you are using the non-asyncio client (due to __aenter__ not being found).

But didn't provide enough details to reproduce your problem.
