Estoy usando MacTex 2015 y Texpad como editor LaTeX. Cuando intento importar el paquete tzik
\usepackage{tikz}
aparecen los siguientes 3 errores
Lo extraño es que todo se ve bien en mi documento.
Todos mis paquetes también están actualizados. ¿Tengo que importar otros paquetes? ¿Alguien experimentó el mismo problema?

Su código para la imagen TikZ tiene un error: usa \draw [-latex] (4) -> (5);en lugar de \draw [-latex] (4) -- (5);. También falta la biblioteca TikZ arrow. Además de esto, mira si el siguiente código de imágenes te resulta útil:
\begin{tikzpicture}[
node distance = 21mm and 11mm,
start chain = going right,
place/.style = {rectangle, draw, thick, minimum size=6mm,
on chain}
]
\node[place] (4) {Shrinked Dataset};
\node[place] (5) {Weighting Features};
\node[place] (1) {SVM Classifier};
\node[place] (2) {Model};
%
\node[place] (3) [below=of 1] {Performances (fitness) Evaluation};

\draw[-latex] (4) edge (5)

\draw[-latex] (3) -- node[fill=white] {$p_i$} (5);
\draw[-latex] (3) -- node[fill=white] {$C$ and $\gamma$} (1);

Necesita bibliotecas Tikz chainsy positioning, es decir, en el preámbulo debe agregar \usetikzlibrary{arrows,chains,positioning}. El código anterior da:
