Tensorflow dataset from numpy array Tags: keras, numpy, python, tensorflow I have two numpy Arrays (X, Y) which I want to convert to a tensorflow dataset. According to the documentation it should be possible to run 3 1 train_dataset = tf.data.Dataset.from_tensor_slices( (X, Y)) 2 model.fit(train_dataset) 3

1. train_dataset = tf.data.Dataset.from_tensor_slices( (X, Y)) 2. model.fit(train_dataset) 3. . When doing this however I get the error: ValueError: Shapes (15, 1) and (768, 15) are incompatible. This would make sense if the shapes of the numpy Arrays would be incompatible to the expected inputs/outputs. But if I run it with the numpy arrays by ...

Method 1: Using the numpy () method. If you have already installed the latest version and Eager Execution is already enabled. Then you can directly use the your_tensor.numpy () function. For example, I want to convert the tensor created in step 2 to the NumPy array, then I will execute the following lines of code.

11.11.2021 · This tutorial provides an example of loading data from NumPy arrays into a tf.data.Dataset. This example loads the MNIST dataset from a .npz file. However, the source of the NumPy arrays is not important. Setup import numpy as …

Jul 29, 2021 · as_numpy converts a possibly nested structure of tf.data.Dataset s and tf.Tensor s to iterables of NumPy arrays and NumPy arrays, respectively. Note that because TensorFlow has support for ragged tensors and NumPy has no equivalent representation, tf.RaggedTensor s are left as-is for the user to deal with them (e.g. using to_list () ).
