Use thenp.random.seed()function to set the seed for the random number generator. For instance, First, import the NumPy library and use the aliasnp. Set the seed to a specific value, in this case, 42. You can re

For this purpose, we will usenumpy.intersect1d()method which is used to find the intersection of two arrays. It returns the sorted, unique values that are in both of the input arrays. Let us understand with the help of an example, ...
The Numpy max functionidentifies the maximum value in a Numpy array. So np.max typically takes a single Numpy array as an input, and will return the maximum value (although there are ways to use it where it will return maxima of the rows or columns). In contrast, Numpy maximum (which ...
To select a random number fromarray_0_to_9we’re now going to use numpy.random.choice. np.random.seed(0) np.random.choice(a = array_0_to_9) OUTPUT: 5 If you read and understood thesyntax section of this tutorial, this is somewhat easy to understand. But there are a few potentially...
Web apps are still useful tools for data scientists to present their data science projects to the users. Since we may not have web development skills, we can use open-source python libraries like Streamlit to easily develop web apps in a short time.
In this quick tutorial, I am going to show you two simple examples to use the sparse_categorical_crossentropy loss function and the sparse_categorical_accuracy metric when compiling your Keras model.Example one - MNIST classificationAs one of the multi-class, single-label classification datasets, ...
Finding the first non-zero value in every column of a NumPy array For this purpose, we will define a function inside which we can usenumpy.argmax()along that axis (zeroth axis for columns here) on the mask of non-zeros to get the indices of first matches. ...

The choice of seed does not matter. The seed() function will seed the pseudorandom number generator, taking an integer value as an argument, such as 1 or 7. If the seed() function is not called prior to using randomness, the default is to use the current system time in milliseconds ...
