\section{Miniforge}

First, we install \textit{Miniforge}. It is a package manager for conda packages and by default set up to use the \texttt{conda-forge} repository. Download the installer from here
\url{https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-Windows-x86_64.exe}
and install Miniforge. We recommend to leave the default settings especially to install Miniforge just for your user (\textit{Just Me}). This does not require admin rights. When the installation has finished, close the window and continue on command line.
\smallskip

\noindent
\begin{minipage}{0.6\linewidth}
%   \setlength{\parindent}{\myindent}
  For that start \textit{Miniforge Prompt} from the start menu.
  In the prompt the \texttt{base} environment should be activated, which looks like this for a user \textit{john}:
\end{minipage}%
\hfill%
\begin{minipage}{0.37\linewidth}
  \includegraphics[width=\linewidth]{images/mambaforge-start-menu-prompt}
\end{minipage}%
\begin{lstlisting}[gobble=2]
  #*\color{gray}(base) C:\textbackslash Users\textbackslash john>*
\end{lstlisting}
Now we are ready to install the packages we need.



\section{Packages}
\label{sec:packages}

Let's create a new environment called \textit{weai} and add the packages we need to it (copy \& paste black text lines):
\begin{lstlisting}[gobble=2, basicstyle=\ttfamily\footnotesize]
  #*\color{gray}(base) C:\textbackslash Users\textbackslash john>*mamba create -n weai python=3.9 astunparse matplotlib ^
                                            ipympl mypy jupyter notebook spyder ^
                                            scikit-learn seaborn openpyxl odfpy ^
                                            pyarrow pandas
\end{lstlisting}
You will get a list of packages and can confirm with \keyenter. Installation takes a while. Since \lstinline|tensorflow| is not yet available for Windows on \texttt{conda-forge}, we need to install it from \textit{PyPI} using \lstinline|pip| into the \textit{weai} environment:
\begin{lstlisting}[gobble=2]
  #*\color{gray}(base) C:\textbackslash Users\textbackslash john>*mamba activate weai
  #*\color{gray}(weai) C:\textbackslash Users\textbackslash john>*pip install tensorflow==2.10.1
\end{lstlisting}
If you have an NVIDIA GPU and want to activate support for it, install the following packages:
\begin{lstlisting}[gobble=2]
  #*\color{gray}(weai) C:\textbackslash Users\textbackslash john>*mamba install cudatoolkit cudnn
\end{lstlisting}
and optionally (not required for Spyder) also add the path to the corresponding libraries (e.\,g.\ \textit{cudnn64\_8.dll}) in your user environment variable \lstinline|Path|, for example:
\begin{lstlisting}[gobble=2, basicstyle=\ttfamily\footnotesize]
  C:\Users\john\miniforge\envs\ml\Library\bin
\end{lstlisting}



\section{Test}
\label{sec:test}

\begin{minipage}{0.6\linewidth}
  Next, we start Spyder from the start menu. The entry is named \textit{Spyder (weai)}, since we installed Spyder into the \textit{weai} environment.
\end{minipage}%
\hfill%
\begin{minipage}{0.37\linewidth}
  \vspace{-3em}
  \includegraphics[width=\linewidth]{images/mambaforge-start-menu-spyder-weai}
\end{minipage}%

\noindent
    The Spyder window opens now. Open the test script \texttt{mnistKeras.py} (\textattachfile{attachments/mnistKeras.py}{attachment}|\href{https://gitlab.cvh-server.de/ckaufmann/install-python-tensorflow-gym/-/raw/master/attachments/mnistKeras.py?inline=false}{web}) and run it by pressing \keystroke{F5} or clicking on the green play button or by using the menu \textit{Run} $\rightarrow$ \textit{Run} and confirm with \textit{Run}.
\vspace{-1ex}

\noindent
\includegraphics[width=\linewidth]{images/spyder-linux}
\vspace{-1.5em} % due to some transparent border in the image

\noindent
The test script will output the TensorFlow version, e.\,g.:
\begin{lstlisting}
=========================
Tensorflow Version 2.10.1
=========================
\end{lstlisting}
Then TensorFlow will download the required data set once and train a neural network. The progress will be printed in the console. Finally the accuracy on the test set will be shown and some sample images will be plotted in the \textit{Plots} pane. This means Python and TensorFlow have been installed successfully.
