Ok, new error time 
Trying to do Lab 2_1A - Introduction to Power Differences (MAIN), the “Empty” Trace section. Getting the following error when trying to run the cw.plot(wave) line, I’ve rebuilt the firmware and uploaded it to the target (Husky & CW308_SAM4S), all the previous blocks have worked from what I can tell.
The error itself:

Any help would be brilliant.
UPDATE: Nevermind, this post had the solution, yet another python module that needs to be downgraded.
In another unrelated question, how do you set the colours of the lines in a cw.plot(waveX)? I assumed it was the same as the usual plt.plot(x,y, color='yellow') but that doesn’t seem to work. Neither does the plt.plot(data, 'g') way as shown in the Introduction to Jupyter Notebooks notebook.
Thanks!
