我在通过任何方法生成对抗性示例时收到以下错误
InvalidArgumentError: assertion failed: [] [Condition x <= y did not hold element-wise:x (Placeholder_173:0) = ] [[[[158 112 49]]]...] [y (Cast_6:0) = ] [1]
[[{{node assert_less_equal_1/Assert/AssertGuard/Assert}}]]
我的生成对抗样本的代码
from cleverhans.utils_keras import KerasModelWrapper
from cleverhans.attacks import FastGradientMethod
model=build_model()
sess = K.get_session()
wrap = KerasModelWrapper(model)
fgsm = FastGradientMethod(wrap, sess=sess)
fgsm_params = {'eps': 0.3,
'clip_min': 0.,
'clip_max': 1.}
adv_x = fgsm.generate_np(x_test, **fgsm_params)
此处的模型代码 tensorflow 版本 = 1.13.1
