Question on HW2

[adamscottc]

Hi Dr. Gilpin, when I took the section of code you wrote to test my class definition, I'm getting a "module object is not callable" error that occurs at the plt.figure() for the model.stored_eigenvalues object. Do you have any tips for how to get rid of this? I looked up the error and apparently it occurs when you try to import a module and then try to call it as a function.

[williamgilpin]

hi, is this when you import my code and then run it in your notebook? or is it a class within your code?

[adamscottc]

It's a class in my code.

Does the following run:

plt.plot(model.components_, '.')

If so, then the problem is probably with the eigmax_numpy function rather than your code

[adamscottc]

The plt.plot function doesn't run, but the eigmax_numpy function does work in the previous line where I print out the final solution. The print(model.singular_values_) also works.

okay that's weird that the eigs print but the plotting isn't working. It sounds like there might be a () somewhere there shouldn't be, since parentheses trigger a variable being treated like a function. Another option would be that matplotlib is struggling. Does plt.plot(np.ones(100)) work?

[adamscottc]

I guess I just can't tell why Matplotlib wouldn't be working. Substituting np.ones(100) didn't plot either

Okay that's a good sign, that just means it's a matplotlib issue. Just out of curiosity, do you have plt.plt anywhere in your code (note that there is no o in either)? Otherwise, my guess is that plt.plot got reassigned somehow, re-running import matplotlib.pyplot as plt might fix it (or just saving and restarting the notebook)

[adamscottc]

That worked. Thank you!

HI Dr. Gilpin! I'm working on problem 2, but Visual Studios isn't recognizing the ipywidgets library. I made sure to install the library using the Anaconda Prompt, but that didn't make a difference. Any advice?

[williamgilpin]

Hi, if you installed the library, you might need to re-start your kernel / close-and-reopen the notebook before Jupyter will recognize it

If it's still not working, it's fine to just ignore the code cells requiring the widgets, those cells are just so you can play with the dataset

[leviyevalex]

If you would still like to play with the widgets, I'd recommend just opening the notebook with Jupyter, sometimes there are missing plugins, etc... in vscode. It will work natively in Jupyter
