Hi,

I want to input this TikZ file : 

\pagestyle{empty}

\def\layersep{2.5cm}

\begin{tikzpicture}[shorten >=1pt,->,draw=black!50, node distance=\layersep]
        \tikzstyle{every pin edge}=[<-,shorten <=1pt]
        \tikzstyle{neuron}=[circle,fill=black!25,minimum size=17pt,inner sep=0pt]
        \tikzstyle{input neuron}=[neuron, fill=green!50];
        \tikzstyle{output neuron}=[neuron, fill=red!50];
        \tikzstyle{hidden neuron}=[neuron, fill=blue!50];
        \tikzstyle{annot} = [text width=4em, text centered]

        % Draw the input layer nodes
        \foreach \name / \y in {1,...,4}
        % This is the same as writing \foreach \name / \y in {1/1,2/2,3/3,4/4}
        \node[input neuron, pin=left:Input \#\y] (I-\name) at (0,-\y) {};

        % Draw the hidden layer nodes
        \foreach \name / \y in {1,...,5}
        \path[yshift=0.5cm]
            node[hidden neuron] (H-\name) at (\layersep,-\y cm) {};

            % Draw the output layer node
        \node[output neuron,pin={[pin edge={->}]right:Output}, right of=H-3] (O) {};

        % Connect every node in the input layer with every node in the
        % hidden layer.
        \foreach \source in {1,...,4}
        \foreach \dest in {1,...,5}
            \path (I-\source) edge (H-\dest);

            % Connect every node in the hidden layer with the output layer
        \foreach \source in {1,...,5}
        \path (H-\source) edge (O);

        % Annotate the layers
        \node[annot,above of=H-1, node distance=1cm] (hl) {Hidden layer};
        \node[annot,left of=hl] {Input layer};
        \node[annot,right of=hl] {Output layer};
\end{tikzpicture}
% End of code

When I build the corresponding LaTeX file containing also these lines at the begining : 

\documentclass[preview]{standalone}
\usepackage{tikz}
\begin{document}

and \end{document} at the end, it builds fine and I get this PDF file: neuralNetwork.pdf or this PNG picture : neuralnetwork

but when I run this cell :

%reload_ext tikzmagic
%tikz \input{neuralNetwork.tikz}

I get this log although luatex and lualatex are installed : 

LaTeX terminated with signal -1

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.

Here is how much of TeX's memory you used:

Can you please help me ?

Hi, here is the output of pdflatex simplified using texfot : 

/usr/bin/texfot: invoking: pdflatex --shell-escape toto.tex

and here is the 37th line of neuralNetwork.tikz

$ sed -n "37p" neuralNetwork.tikz

Any idea ?

A friend of mine solved the pb., I had to comment : 

\begin{tikzpicture}
\end{tikzpicture}

in my neuralNetwork.tikz because they are already added by your tikzpython function.
