WebA function which will be invoked at the end of every epoch. Its signature should be: (epoch, n_epochs, coords), where: epoch The current epoch number (between 1 and n_epochs ). n_epochs Number of epochs to use during the optimization of the embedded coordinates. WebThe seed () method is used to initialize the random number generator. The random number generator needs a number to start with (a seed value), to be able to generate a random number. By default the random number generator uses the current system time. Use the seed () method to customize the start number of the random number generator. WebDec 10, 2024 · Yes it is.
