Well, after some googling, It seems there's a problem in your GUI backend for matplotlib. Does the following code work for you?

import matplotlib
import matplotlib.pyplot as plt 
plt.plot([1,2,3])

and

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt 
plt.plot([1,2,3])

i also googling.
please help me.

So the issue is not related to deepvoice3_pytorch. Please ask a question or file an issue to matplotlib community. I cannot reproduce.

@ManivannanMurugavel I have the same problem as you. Could you show me the way to fix it? Really appreciate!

@toannhu Please remove matplotlib for loss and accuracy graph.
Just see the what training acc and loss in terminal.
Solution:
Please command the all save_alignment() def inside train.py.
