In the following, if you are asked to run a command like
$ run this command
it means that you should type run this command in the terminal and press Enter.
You only need to install Anaconda and git if you don't have it already on your computer. To check if you have git already, you can run
$ where git
If it returns something, you have git already. To test if you have Anaconda or Miniconda, run
$ where python
If it returns a path like ../anaconda3/bin/python, you already have the correct Anaconda/Miniconda distribution and you can skip this step.
Download Miniconda https://conda.io/miniconda.html with Python 3.7.
To start the installer run
$ bash Miniconda3-latest-Linux-x86_64.sh
Most options can just be answered with yes, however you should insist on adding conda to your PATH when the installer asks you.
Start the graphical installer, it should guide through the installation process. If you don't have another python-installation already installed, you can safely add python to your %PATH%, such that you can it from your normal cmd-shell. In any case, you should have a program named "Anaconda prompt" installed afterward, which you can find with the start menu. If you didn't add it to your %PATH% as instructed above, you need to run all conda-commands in the Anaconda prompt, otherwise you can use the normal cmd or Powershell.
If you want to install an environment, make sure you have Admin-rights for the terminal you use. To do that, hit Win+X, and select either Powershell as Administrator or cmd as Administrator, depending on what your Windows offers you.
You can test if you have the correct python-version there by typing python --version, which should tell you it's Python 3.6.x
To install, open a terminal and run
$ sudo apt-get install git
Install Homebrew if you don't have it already from https://brew.sh/. Then run
$ brew install git
Download the .exe from https://git-scm.com/download/win and run the installer.
In the install wizard, make sure that git can be used from the command prompt, otherwise you'd have to switch between shells when coding and committing to git.To make sure your solution will be accepted once pushed, you need to set one of the two commit unix style options. Other than that, you'll probably go for the openSSL as well as Windows default console as terminal emulator options.
Next you have to create the correct virtual environment for working on your homework. For that, you can clone our lecture-repository. To do so, enter the terminal and navigate to a directory (cd) where you want to put your homework. Run
$ git clone https://github.com/scientificprogrammingUOS/lectures.git
to clone the repository. Afterwards, you can create the environment using
$ conda env create -f lectures/environment.yml
This will create a new environment and install all the necessary packages needed for this course. Instead of cloning the repository you can also simply download the raw yaml from https://raw.githubusercontent.com/scientificprogrammingUOS/lectures/master/environment.yml and create the environment using conda env create -f path/to/environment.yml.
Afterwards, you need to activate the environment.
To activate the environment, run
$ conda activate scientific_programming
If you didn't add conda-commands to your %PATH%, you'll ned to open the program Anaconda prompt. It will give you a typical Windows cmd-style shell. The command to activate the environment is
$ conda activate scientific_programming
as well. Your shell should indicate the environment you are in if it worked.
Always activate the environment when you work on the homework. To deactivate the
environment again, run conda deactivate on all systems.
To open the Python interpreter run
$ python
the prompt should start with something like
Python 3.6.3 |Anaconda, Inc.|
close the interpreter again by running
>>> quit()
