Extracting the real and imaginary parts of a NumPy array of complex numbers
In Python, we can extract the real and imaginary parts of a NumPy array of the complex number using the real and imag attributes of the array, respectively. Numpy is a Python library that is used for complex calculations and also provides support for complex numbers. In this article, we will understand how we can extract the real and imaginary parts separately of a complex number. Understanding Complex Number in Numpy In Numpy we represent a complex number as a combination of the real and imaginary parts using the complex data type. We can create a complex number in ...
Read MoreDifference Between Dataset.from_tensors and Dataset.from_tensor_slices
Dataset.from_tensors and Dataset.from_tensor_slices are methods in the TensorFlow library that are used to create datasets. Dataset.from_tensor creates a dataset from a single tensor whereas Dataset.from_tensor_slices creates data set by slicing a tensor along the first dimension. In this article, we will understand the difference between the two methods and how they are used in different use cases. from_tensor from_tensor_slices Creates a dataset from a single tensor Creates a dataset by slicing a tensor along the first dimension Useful for small datasets that can fit in memory Useful for large datasets that ...
