Thank you, @Tobias_Schadauer!!
This used to work, so there must have been an update to seaborn. I’ll let the developers know so they can update the assignment to work with the current version of seaborn.
In the meantime, anyone else who runs into this issue, you can make the change @Tobias_Schadauer suggests like this to see the plot:
res = sns.jointplot([ samples[:, 0], samples[:, 1] ], kind=“kde”)
That will let you see the plot, but you’ll need to remember to take the brackets you added back out before you submit your assignment until this gets fixed.
