from one of our readers: In the introduction of quantecon lecture it discussed np.rank. I could not run it so I check and according to this website https://numpy.org/devdocs/release/1.18.0-notes.html it looks like numpy.rank has been removed. I still can run it on Pythonista but I cannot run it on Jupyter notebook. You might want to check if you have the same problem and correct if the rest of the lecture implement it.
