Did you use Theano backend or Tensorflow backend? The ValueError: too many values to unpack
seems to indicate that you are using Theano as backend.
I am using tensorflow as backend. Using TensorFlow backend.
Below is my model structure if it helps model = Sequential([ ZeroPadding2D(padding=(0,2),input_shape=input_shape), Conv2D(filters=256, kernel_size=(1, 3), padding='valid',activation="relu", name="conv1", kernel_initializer='glorot_uniform'), Dropout(0.5), ZeroPadding2D(padding=(0,2)), Conv2D(filters=80, kernel_size=(2, 3), padding='valid',activation="relu", name="conv2", kernel_initializer='glorot_uniform'), Dropout(0.5), Flatten(), Dense(256, activation="relu", name="dense1", kernel_initializer='he_normal' ), Dropout(0.5), Dense(11, name="dense2", kernel_initializer='henormal'), Activation('softmax'), Reshape([11])]) since I am new to tensorflow, I am struggling to figure out why it produces ValueError at line logits, = ybar.op.inputs. Any help is appreciated.Thanks.
After removing last layer Reshape([11]). it works perfectly fine. Not sure why it didn't like the Reshape layer.
It makes sense. The ybar.op.inputs
is the input for softmax
operation, i.e., logits, input for Reshape
operation may be different, you could print ybar.op
to see what's available. It is Keras internal implementation, this ybar.op.inputs
is more of a hack, and might be changed in later Keras version.
Hi,
I tried to change the model to one similar to(https://github.com/radioML/examples/blob/master/modulation_recognition/RML2016.10a_VTCNN2_example.ipynb) this model. Where total params is 2,830,427 (way more than your simple model). While generating adversarial crafting graph, I receive the following error Traceback (most recent call last): File "RML_TOS.py", line 121, in
x_adv = fgsm(_model_fn, x, epochs=9, eps=0.0001)
File "/home/pduraisamy/Adversarial/adversarial/fgsm.py", line 23, in fgsm
ybar = model(x_adv)
File "RML_TOS.py", line 117, in _modelfn
logits, = ybar.op.inputs
ValueError: too many values to unpack
Exception AttributeError: "'NoneType' object has no attribute 'path'" in <function remove at 0x7fb07c21f140> ignored
Does it mean it couldn't handle deep network? Appreciate your help.
