Citation label instead of number of reference

Question

I have a problem regarding the bibliography in my document. My code is the following:

\documentclass[runningheads,a4paper]{llncs}
\usepackage{amssymb}
\setcounter{tocdepth}{3}
\usepackage{graphicx}
\usepackage{url}
\usepackage{hyperref}
\usepackage[backend=bibtex]{biblatex}

\begin{document}

Hello world! \cite{wu2015deep}

\begin{thebibliography}{1}

\bibitem{wu2015deep} Wu J, Yu Y, Huang C., Yu K. Multiple Instance Learning for Image Classification and Auto-Annotation. In CVPR 2015, pp. 3460--3469
\end{thebibliography}

\end{document}

And the output of my code is the following:

As you can see instead of [1], the reference is [wu2015deep]. Do you have any idea what is the problem that's causing this? I am using TeXMaker 4.5, compiling with the option: pdflatex + Bib(la)tex + pdflatex (x2) + View PDF

Thank you very much in advance for your time and help! :)

You can't mix biblatex with thebibliography and \bibitem. You need a bib file with your entry. — Ulrike Fischer, Feb 03 '17 at 15:24
As Ulrike says, you can't mix the manual way of creating a bibliography (thebibliography) with the automatic way of biblatex. If you want to use biblatex, refer to biblatex in a nutshell (for beginners), What to do to switch to biblatex? and linked questions. A nice starter guide is https://heim.ifi.uio.no/~dag/latex-links/biblatex-guide.pdf — moewe, Feb 03 '17 at 16:14

With the following code you will get the [1]:

\documentclass[runningheads,a4paper]{report}
\usepackage{amssymb}
\setcounter{tocdepth}{3}
\usepackage{graphicx}
\usepackage{url}
\usepackage{hyperref}
\usepackage{acronym}

\begin{document}

Hello world! \cite{wu2015deep}

\begin{thebibliography}{----}

\bibitem{wu2015deep}
%\textsc{Wu},  J. \textsc{Yu}, Y.  \textsc{Huang} C. \& \textsc{Yu} K. (2015) {\it Multiple Instance Learning for Image Classification and Auto-Annotation.} In CVPR 2015, pp. 3460--3469
Wu J, Yu Y, Huang C., Yu K. Multiple Instance Learning for Image Classification and Auto-Annotation. In CVPR 2015, pp. 3460--3469
\end{thebibliography}

\end{document}

Thank you very much for your answer! It worked but I had to do one more thing, compile it with the option pdflatex + View PDF. — Maggie, Feb 03 '17 at 16:14
