Invalid literal

[peddinti]

When I am trying to run the example. But i am facing this issue at this line

xmb[i, -l:] = list(x)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: invalid literal for long() with base 10: '\n'

Can you provide your system environment and the input?

I got the same problem. In my case, it occurred because the length of my sentence was greater than the mentioned nsteps in the code
