            Dimensionality problem with PyTorch Conv layers
            Asked 2022-Apr-08 at 17:55

            I'm trying to train a neural network in PyTorch with some input signals. The layers are conv1d. The shape of my input is [100, 10], meaning 100 signals of a length of 10.

            But when I execute the training, I have this error: Given groups=1, weight of size [100, 10, 1], expected input[1, 1, 10] to have 10 channels, but got 1 channels instead

            ...

            ANSWER

            Answered 2022-Apr-08 at 17:55

            nn.Conv1d expects input with shape of form (batch_size, num_of_channels, seq_length). It's parameters allow to directly set number of ouput channels (out_channels) and change length of output using, for example, stride. For conv1d layer to work correctly it should know number of input channels (in_channels), which is not the case on first convolution: input.shape == (batch_size, 1, 10), therefore num_of_channels = 1, while convolution in self.layers[0] expects this value to be equal 10 (because in_channels set by self.config[0] and self.config[0] == 10). Hence to fix this append one more value to config:

            i am bit confused about the output shape of keras layer. I have created a sample keras model and also displayed its summary.

            ANSWER

            Answered 2021-Nov-24 at 08:30

            Since you set the parameter return_sequences to True in the LSTM layer, you are getting a sequence with the same number of time steps as your input and an output space of 1 for each timestep, hence the shape (None, 129, 1). Afterwards, you apply a Dense layer to this tensor, but this layer is always applied to the last dimension of a tensor, which in your case is 1 and not 129. Therefore you get the output (None, 129, 64). Then, you use a final output layer, which is also applied to the last dimension of your tensor resulting in output with the shape (None, 129, 1). The Tensorflow docs also explain this behavior:

            If the input to the layer has a rank greater than 2, then Dense computes the dot product between the inputs and the kernel along the last axis of the inputs and axis 0 of the kernel (using tf.tensordot).

            You can set return_sequences to False if you want to work with a 2D output (batch_size, features) instead of 3D (batch_size, time_steps, features), or you can use the Flatten layer.

            You are missing exactly the last step in Keras transformation.

            There is also a Sequential() class in TensorFlow(Keras) that you can use to instantiate the model.

            I haven't checked for the exact match between TF and PyTorch, but this should be your starting point to solve your problem.

            Thanks for using PyGAD.

            I see that you built the example correctly. You can easily use the best solution to make predictions using simple 3 steps.

            Please note that after each generation, the population attribute is updated by the latest population. That means after PyGAD completes all the generations, the last population is saved in the population attribute.

            Step 1

            After you load the saved model using the pygad.load() function, and as you did in the fitness function, you can use the population attribute to restore the weights of the networks as follows:
