Numpy load matrix from text file. In a previous tutorial we talked about numpy arrays and we saw how it makes the process of reading parsing and performing operations on numeric data a cakewalk in this tutorial we will discuss the numpy loadtxt method that is used to parse data from text files and store them in an n dimensional numpy array. Plain text files txt comma separated values files csv plain text files. To load a csv comma separated values file we specify delimitter to.
