Error while start driving

[chapmantam]

I follow your the steps.

1. clone this github link and install donkeycar.
2. Create a car by "donkey createcar mycar"
3. Then I create a certificate and download all the key and certificate to the donkey car.
4. Change the config.py with the correct path.
5. pip install AWSIotPythonSDK
6. Once I want to start the driving by typing the command python manage.py drive, it got an error:

   (env) pi@mypi:~/mycar2 $ python manage.py drive
   using donkey v2.5.1 ...
   /usr/lib/python3/dist-packages/h5py/_init_.py:34: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
   from ._conv import register_converters as _register_converters

   File "manage.py", line 133, in drive
   iot = aws.new_iot_publisher(intputs=inputs, types=types)
   TypeError: new_iot_publisher() got an unexpected keyword argument 'intputs'

   How to fix it?

This should be an issue in the donkey project, created issue in chankh/donkey#2 for tracking.

[chankh]

@chapmantam this issue should be fixed in chankh/donkey, please checkout the latest code and try again

[chapmantam]

the previous problem is fixed but another comes, it shows another error:

I have already changed the config.py accordingly. (I have renamed the cert and private key and put it on the same folder on the created car folder).

Is there any extra step I need to do ?

[chankh]

@chapmantam try using absolute path instead, like /home/pi/d2/private.pem.key and /home/pi/d2/certificate.pem.key

After git pull and re createcar again, Another problem exists:

Do you know how to fix it? Thank you

[chankh]

Looks like a connection issue, is your pi connected to internet? Check if you can access the iot endpoint.

I have checked that there is no problem on the internet. It can also pin to google.com I also checked the monitor in aws iot, it shows nothing about the connection. I don't think it has connected to iot . Do you have any suggestion?

[chapmantam]

the problem is fixed . I forgot to add the endpoint into the config.py after re-createcar. After I rechange the CA root certificate, then the error disappear.
