ddc_challenge: AttributeError: 'flightgym.QuadrotorEnv_v1' object has no attribute 'getFrameDim'

[Praveendwivedi]

hey! I've followed all the steps as mentioned in the readme doc for ddc challenge. As mentioned in step 8 of the doc, when running

cd $FLIGHTMARE_PATH/flightrl/examples && python test_vec_env.py

I got following error:

[UnityBridge]  Initializing ZMQ connection!
[UnityBridge]  Initializing ZMQ connections done!
[VecEnv]       Flightmare Bridge is created.
Traceback (most recent call last):

AttributeError: 'flightgym.QuadrotorEnv_v1' object has no attribute 'getFrameDim'

I checked about available methods of 'flightgym.QuadrotorEnv_v1' in python ide by running: import flightgym help(flightgym)

i got : Help on module flightgym:

As you can see there is no method named 'getFrameDim'. What should I do now :(?
