Today, we’re going to be using the MNIST data set which consists of data showing images of different handwritten digits which are numbers from 0 through 9. We’ll define a variable z_zero and use the PyTorch concatenation function where we pass in the list of our two PyTorch tensors, so x, y, and we’re going to concatenate it by the 0th dimension, so the first dimension. Here is an example: This should shuffle all the 3000 items: dataset = dataset1. After running a container, activate the Conda environment vitis-ai-tensorflow2. from_tensor_slices({'f1': list(range(20)), 'f2': [1]*20}) ds2 = tf. datasets. tf. reduce, lambda x, y: x. When we want to combine two data sets by merging in SAS and we know beforehand that each observation in the data set has a match in the other dataset we can do a very straight-forward merge. 0). The Keras functional API is the way to go for defining complex models, such as multi-output models, directed acyclic graphs, or models with shared layers. tensorflow concatenate datasets
