When I run below code:
model.output(samples).getDouble(0);
I receive error:
org.deeplearning4j.exception.DL4JInvalidInputException:
Cannot do forward pass in Convolution layer (layer name = conv1d_1, layer index = 0): input array channels does not match CNN layer configuration
(data input channels = 80, [minibatch,inputDepth,height,width]=[1, 80, 3, 1]; expected input channels = 3)
(layer name: conv1d_1, layer index: 0, layer type: Convolution1DLayer)
I created the data as float[] array, with length = 240.
Creation of INDArray:
INDArray features = Nd4j.create(data, new int[]{1, 240}, 'c');
Here is my keras model:
model = Sequential()
model.add(Reshape((const.PERIOD, const.N_FEATURES), input_shape=(240,)))
model.add(Conv1D(100, 10, activation='relu', input_shape=(const.PERIOD, const.N_FEATURES)))
model.add(Conv1D(100, 10, activation='relu'))
model.add(MaxPooling1D(const.N_FEATURES))
model.add(Conv1D(160, 10, activation='relu'))
model.add(Conv1D(160, 10, activation='relu'))
model.add(Flatten())
model.add(Dropout(0.5))
model.add(Dense(7, activation='softmax'))
model.summary()
model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
Where PERIOD = 80, N_FEATURES = 3
If I set shape as:
INDArray features = Nd4j.create(data, new int[]{240, 1});
Then error is:
IllegalStateException: Input shape [240, 1] and output shape[240, 1] do not match
