udacidrone breaks when running on Python 3.7

[cptanalatriste]

I'm trying to use udacidrone to run code on a Crazyflie, using an Anaconda environment with Python 3.7 installed (as required by the Crazyflie Python client. However, when running the udacidrone code I gert the following:

Traceback (most recent call last):

    from udacidrone.connection import CrazyflieConnection  # noqa: F401

                                        ^
SyntaxError: invalid syntax

It appears the websocket version is generating invalid Python 3.7 code. I tried updating websockets, but it breaks in many other ways.

Is there a workaround for udacidrone to work on Python 3.7?

Hey @cptanalatriste, have you managed to solve this issue? It's still reproducing.

Hey, I managed to modify websocket so that it's working with udacidrone on Python3.7. I have made a Dockerfile https://github.com/yfe404/Drone-Flight-Controller-Sim-Backyard-Flyer but alternatively you can just replace

/usr/local/lib/python3.7/site-packages/websockets/__init__.py with my custom_init.py /usr/local/lib/python3.7/site-packages/websockets/compatibility.py with my custom_compatibility.py

Sadly, I didn't manage to get it working. I ended abandoning the Crazyflie during the Nanodegree :(

Really sad to hear this about the program which positions itself as paid personalized people-oriented experience.

Anyway, for those who having trouble creating conda env with python==3.6 on MacOS M1, try to install conda for x86 instead of arm64
