Unable to Plot 3d Function Using Matplotlib

Question

I am trying to plot a 3d function in python using matplotlib. For some reason I get the error "Invalid syntax (pyflakes E)" in the second line of the code provided when trying to plot it. I got this part from another person, and this works for them. The packages from matplotlib I have installed are mplot3d, cm, and Subplot. Perhaps there is another package I need?

fig = plt.figure(figsize=(12,12))
ax = fig.add_subplot(projection='3d')

Are you using Spyder? This is seemingly not a maptlotlib problem. Can you post the full traceback of the error message and include matplotlib version and how you installed it? — Mr. T

It seems that you need to use ax = plt.axes(projection = 3d)

The syntax of the code in the question is perfectly fine. Have you tried it?

I have not actually tried it. I guess I assumed since there is an error it won't run. It is for a neural network model. I am running the model right now, once it is done I will try and plot it and see if it works.

So I tried it and it ran. That is weird I was not expecting that. Any idea why it would be giving me a syntax error but still running?
