Pre-trained model does not work #24

Open apuder opened 6 years ago

I'm using Tensorflow 1.7 and Keras 2.1.6. Doing a git clone followed by "python qlearn.py -m Run" should run the pre-trained model, right? However, the result does not look good. Flappy Bird immediately crashes at the first pipe.

I figured out what happened. In a recent commit 26cceb4 the scaling of the pixel values to range [0-1] was added. This is inconsistent with the pre-trained model. Reverting commit 26cceb4 makes the pre-trained model work again. The model should be updated with the change that was introduced in that commit.

Ascott02's model solved this issue for me
