Lack of "plt.style.use('./deeplearning.mplstyle')"

I’m having difficulty running the labs due to the lack of “plt.style.use(‘./deeplearning.mplstyle’)”. I use VSCode.

I request guidance on how to run it locally.

Did you download the entire workspace folder? Or just the notebook. That could be the reason.

I believe that’s covered in the course FAQ.

Yes, I downloaded all the content. For example, if I run:
import numpy as np
%matplotlib widget
import matplotlib.pyplot as plt
from plt_one_addpt_onclick import plt_one_addpt_onclick
from lab_utils_common import draw_vthresh
plt.style.use(‘./deeplearning.mplstyle’)

I receive as an error:

ModuleNotFoundError: No module named ‘ipympl’

From your message, it looks like you just need to install ipympl.
You could do that with
pip install ipympl
Kindly go through the course FAQ for more info.
I also use VSCode and it works for me.

@ Raphael_Garcia_Morei
one more thing you can do is, just remove the plt.style.use(). I think, this doesn’t affect the result but the styles of graphs plotting is not as the team of this course sepecified. Go with this and inform the result later here.
Thank you,
