After initialising python trainTesnorCNN.py python app crashes

Good afternoon! I'm trying to run your code, but it does not work. After the startup trainTesnorCNN.py, the consumed RAM size grows to 1.2 gigabytes and the processor is loaded 100% (all cores and threads) and then immediately closes with the appcrash error of python. I don't understand. My CPU is i5-460m, 4GB Ram (3 gb availible before running).
Thank for you answers!
