dronekit-sitl not work with new version python.

[ghost]

Hello.

it seems that dronekit-SITL not works with newer version python.

it generates error after I update the python.

following error message orrcurs when I connect to dronekit-sitl. :

File "C:\Users\xxx.conda\envs\xxx\lib\site-packages\dronekit\mavlink.py", line 127, in init
if ip.startswith("udpin:"):
AttributeError: 'SITL' object has no attribute 'startswith'

---

I changed all variable to string by str() but since I don't know about entire code structure, I failed.

what version of python are you running?

[ghost]

Im using latest python, 3.9.16

I remember I tried 3.9.10,3.9.0 but I'm not sure about the version I tried.

Thank you for your reply. Im already using virtual environment as you can see in my error message. do you run your dronekit sitl well in windows?

[kyrlon]

I was able to install on my Windows 10 machine, but I have not been successful in running the sitl efficiently. I have been having a similar issue where after 10 secs, the sitl disarms the motors. The only solution is to downgrade to python3.6 and also install pymavlink==2.4.8, which both options I would prefer not to result to.

[kyrlon]

I ended up using a docker container suggested from this repo. I ended up just pulling the image directly

@peterbarker Is there any plan to update Dronekit Sitl to Python 3? It's a pretty useful tool.

[ItayShiff]

Any update on this ?
