In DCGAN got error

[sadra-sharifzade]

when I run this code in the line 66 to 70 I got many errors.(note that I'm not professional at tensorflow and I want a DCGAN program to run, not to learn). first please say in the line 66 to 70 :dataset = (tf.data.Dataset.list_files('./faces/*.jpg') .map(lambda x: (tf.cast(tf.image.decode_jpeg(tf.read_file(x)), tf.float64)/127.5-1, tf.ones(1, tf.int32))) .batch(batch_size) .repeat())

I have these questions:

1. Should I change the './faces/*.jpg' in (tf.data.Dataset.list_files('./faces/*.jpg') to my dataset address?
2. I have '.npy' dataset (which contain a RGB values of each pixel of each picture in numpy array) what should I do?(what parts should be changed?)
