BibLaTeX doesn't generate bibliography

[Marek Poláček]

Hi. I am using TeXstudio for generating my LaTeX documents, and I need to use bibliography with ISO 690 style (with Czech locale). However, BibLaTeX doesn't quite fully support babel with Czech language (see StackExchange question). This is my preamble:

\documentclass[12pt,twoside,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}

\usepackage[shorthands=off,czech]{babel}
\usepackage{csquotes}

\usepackage[style=iso-numeric]{biblatex}
\addbibresource{lab01.bib}

\usepackage{float}
\usepackage{lmodern}
\usepackage{graphicx}
\usepackage{attachfile}
\usepackage{subcaption}
\usepackage{cleveref}
\usepackage[document]{ragged2e}
\usepackage{textcomp}
\usepackage{gensymb}

\usepackage{siunitx}
\sisetup{
    detect-mode,
    detect-family,
    detect-inline-family=math,
    group-separator={.},
    group-minimum-digits={3},
    output-decimal-marker={,}
}

\captionsetup[subfigure]{subrefformat=simple,labelformat=simple}
\renewcommand\thesubfigure{(\alph{subfigure})}

\title{Výkonové polovodičové systémy~I \textemdash\ Laboratorní úloha č.~1\\ \large \emph{Řízený dvoupulzní usměrňovač}}
\author{Marek Poláček (POL0423)\\ VŠB \textendash\ Technická univerzita Ostrava,\\ Fakulta elektrotechniky a~informatiky.}
\date{\today}

And this is what it bibtex.exe prints out:

I found no \citation commands---while reading file lab01.aux
I found no \bibdata command---while reading file lab01.aux
I found no \bibstyle command---while reading file lab01.aux
(There were 3 error messages)

This is what it looks like in generated PDF (it doesn't show at all):
