Jun 26, 2019 · In this post, we’ll look at some of the main ways to use NumPy and how it can represent different types of data (tables, images, text…etc) before we can serve them to machine learning models. We can create a NumPy array (a.k.a. the mighty ndarray) by passing a python list to it and using ` np.array ()`.

How do I plot the contents of a numpy array? matplotlib.pyplot is a module; the function to plot is matplotlib.pyplot.plot. Thus, you should do. A good place to learn more about this would be to read a matplotlib tutorial. Now I get In [66]: plt.plot (cplr) Out [66]: [<matplotlib.lines.Line2D at 0x1077fdad0>] and no plot appears?
