Collect Data

In order to ensure the data collection, it is recommended to control the joystick manually. Enter the virtual environment and run the following command to enable the program to collect data.

cd ~/mycar
python manage.py drive --js

• Practice driving around the track a few times. Make sure you can drive 10 laps correctly without going off the track.
• Run the following command to clear the previously useless data.

rm -r ~/mycar/data/*

• Please restart the python mange.py process to create a new tub session. Press Start Recording if using a network controller. The joystick will automatically record using any non-zero throttle.
• If you crash or run off the track, stop the car immediately to stop the recording. Press the X key to delete the last 5 seconds of the recording.
• After collecting 10-20 laps of good data (5-20​​​k images), you can stop the car by pressing Ctrl+C to exit the program.
• The data you collect is located in the data folder.
