The makemovie command is a great tool to visually inspect and debug your model. Here are some example uses:
To create just a video of the training data, with an overlay that shows steering:
donkey makemovie --tub=pathToYour/data/ --out=outputVideo.mp4
To create a video with an overlay of your model steering and the training data steering:
donkey makemovie --tub=pathToYour/data/ --out=outputVideo.mp4
--model=yourModel.h5 --type=modelType
To create a video with a saliency map and both overlays:
donkey makemovie --tub=pathToYour/data/ --out=outputVideo.mp4
--model=yourModel.h5 --type=modelType --salient
