Are you running on a Raspberry Pi, Windows, Linux, Mac? Miniconda install is recommended for Windows, Linux, Mac. And you have specified the picamera to run.

I am running it on Mac.

I am following steps listed here : https://docs.donkeycar.com/guide/simulator/

Earlier, since I noticed that it was looking for picamera, I did this step (although its not listed in the steps)
export READTHEDOCS=True
pip install picamera

post this, I executed
conda activate donkey

and then
python manage.py drive : and This step is where I get the error posted above.

Did you also follow these instructions: https://docs.donkeycar.com/guide/host_pc/setup_mac/ ?
Did you set DONKEY_GYM = True in myconfig.py? This replaces the Picamera setting. You do not need picamera installed for the Mac. If you are still having a problem, I suggest you attach the myconfig.py file with your settings.

I also suggest you join the Discord server for help instead of posting here. You will likely receive alot more responses.

@unnatis07 It seems you have the RaspberryPi camera selected in your myconfig.py file; that will not work on a Mac. You want to choose either 'MOCK' for no camera or 'CVCAM' to use opencv to access a webcam or laptop camera (you must have installed the optional opencv dependencies to do this).

@unnatis07 Is this still a problem for you? It sounds like a configuration issue. I would like to close this issue; please give us an update.

Thanks Ed. Its not an issue anymore. I solved it but dont recall specifics. Thanks again. On Oct 28, 2022, at 9:02 PM, Ed Murphy ***@***.***> wrote: @unnatis07 Is this still a problem for you?
