Issues when running examples

[Budd00]

Hi, I'm currently running this fuzzer with the code provided in the /examples directory but it doesn't work out. For the dcgan example, I always get 'Fuzzing failed to satisfy objective function.' Just wondering what could be the reason for producing a none result? And for the nan and quantized example, there is an exception: ValueError: Cannot add function '__inference_Dataset_flat_map_read_one_file_44' because a different function with the same name already exists. I'm not sure if it is because there are some defects in TensorFlow 1.

I'm running it using python 3.6.9 and TensorFlow 1.15 by the way.
