```python
import numpy as np
import skimage
import matplotlib.pyplot as plt
import keras
from keras.models import load_model
from keras import backend as K

SHAPE = (68, 218)
adv_image = np.array([np.ones(SHAPE)])
epsilon = 1

model = load_model('model')
print(model.summary())
weights = model.layers[1].get_weights()[0]
weights = weights.reshape(SHAPE)
print(weights, model.predict(np.array([weights])))
skimage.io.imshow(weights)
plt.show()
