+## Course Information (2)
+
+`TensorFlow` and `Keras` are now also installed in the CIP jupyter hub. In addition, with a google account you can run jupyter notebooks on Google Colab:
+

+
+\vfill
+
+Missing python libraries can be included by adding the following to a cell (here for the pypng library):
+
+```
+!pip install pypng
+```
+
+
+## Course Information (3) 
+
+ * Your installation at home:
+   * \textcolor{blue}{Web Browser to access jupyter3}
+   * \textcolor{blue}{Access to the CIP pool via an ssh client on your home PC}
+   
+ * No requirements for a special operating system
+
+ * Software:
+   * firefox or similar
+   * Cisco AnyConnect
+   * ssh client (MobaXterm on Windows, integrated in Linux/Mac)
+
+ * Local execution of python / iPython
+   * Install ``anaconda3`` and download / run the iPython notebooks (also python  scripts are available)
+

+## Course Information (4)
+Alternatively, you can install the libraries needed on your local computer.
+
+\vfill
+
+Here are the relevant instruction for macOS using `pip`:
+
+\vfill
+
+Assumptions: `homebrew` is installed.
+
+\vfill
+
+Install python3 (see https://docs.python-guide.org/starting/install3/osx/)
+\footnotesize
+```
+$ brew install python
+$ python --version
+Python 3.8.5
+```
+\normalsize
+
+
+Make sure pip3 is up-to-date (alternative: conda  $\rightarrow$ don't mix conda and pip installations)
+\footnotesize
+```
+$ pip3 install --upgrade pip
+```
+\normalsize
+
+
+Install modules needed:
+\footnotesize
+```
+$ pip3 install --upgrade jupyter matplotlib numpy pandas 
+scipy scikit-learn xgboost iminuit tensorflow tensorflow_datasets Keras
+```
