Dear yt:
I am getting the error as below while plotting streamplots. Could you let
me know what is causing this problem? drive link to my code
(yt_frb_streamplot.py) is also below.

In your script, where you have:
plt.streamplot(X, Y, U, V, density=2,color='blue')
replace that with:
plt.streamplot(X, Y, np.array(U), np.array(V), density=2,color='blue')
U and V have units attached, but streamplot doesn't know about yt's unit
system, so you need to make sure they're plain old ndarrays (with no units)
before passing them to matplotlib.
