Missing \\ about array_to_latex

[xansiaux]

Thank's a lot!
That was the problem.
Without 'print' , it works.
Have a good day!

I've never typed them in. Does it not compile ok?

Thanks a lot for your answer.

And excuse me: I was thinking that the code doesn't compile without backslashes, but it does.

I compile with miktex2.9:

\begin{pycode}
import numpy as np
import array_to_latex as a2l

A = np.array([[1.23456, 23.45678],[456.23, 8.239521]])
print(str(a2l.to_ltx(A, frmt = '{:6.2f}', arraytype = 'pmatrix')))
\end{pycode}

and I obtain this:

I don't understand why.
Sorry.

I don't either, but you're running python inside LaTeX so it could be on the LaTeX side. In python, it works fine.

The str command is likely unnecessary. In fact, the print command isn't necessary either. It results in the extra "None" you see.
