AttributeError: 'Tensor' object has no attribute 'numpy'
someone has this problem in notebook v2 / know what can be the problem
the error on this line:
patch, patch_mask = ap.generate(x=images, y=y_target)

THE CODE CELL:

ap = AdversarialPatch(classifier=tfc, rotation_max=rotation_max, scale_min=scale_min, scale_max=scale_max,
learning_rate=learning_rate, max_iter=max_iter, batch_size=batch_size,
patch_shape=(128, 128, 3))

label = name_to_label(target_name)
y_one_hot = np.zeros(nb_classes)
y_one_hot[label] = 1.0
y_target = np.tile(y_one_hot, (images.shape[0], 1))
patch, patch_mask = ap.generate(x=images, y=y_target)

THE TYPE OF images AND y_target WAS :
<class 'numpy.ndarray'>

Hi @estheroratemstet Can you share more information?

Hi @estheroratemstet I was able to reproduce your error by disabling TensorFlow eager execution. You can solve this problem by enabling eager execution or upgrading Tensorflow to version 2.2.0 or above (because it is enabled by default)

Either

import tensorflow as tf
tf.enable_eager_execution()

or pip install tensorflow --upgrade
