If you want to use your Local Machine then I recommend you guys to create a Virtual Environment and get the work done. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Logs. This is actually designed by people with really good IQ. It used 5x5 filters, average pooling, and no padding. Here I have given the target_size as 224, this is because the input to the ConvNets is a fixed size which is 224*224 RGB image as stated in the VGG 16 architecture paper. But the problem was that starting from some size of layers, it started to not learn anything.

Instantiates the VGG16 model. Vgg16 is a convolutional neural network model proposed by K. Simonyan and A. Zisserman from the University of Oxford in the paper "Very Deep Convolutional Networks for Large-Scale Image Recognition". The remarkable thing about VGG was that, instead of having so many hyperparameters, the authors used a much simpler network, where the focus was on using convolutional layers with small sizes of 3x3 filters, with a stride of 1 and using the same padding, and make all the MaxPooling layers 2x2 with a stride of 2. Everything runs fine but when I decode the prediction, the result I get is very strange. Second, extracting data batch out of the whole dataset is not exhaustive, i.e. It has three Conv layers with 256 filters followed by Max Pooling. with pixels values in the range of 0-255 and subtracts the mean image values (calculated over the entire ImageNet training set).
