## To do the homeworks you need to use emacs and python; it is
## recommended to install/use [anaconda/miniconda](https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html),
## - emacs is the required IDE for the class. It allows you to write/edit
##   code without using the mouse, and has great python support,
##   including conda environments, interactive execution, completion, ...
##   - [My emacs and python screencasts show you how to install emacs and configure it to work with python](https://www.youtube.com/playlist?list=PLwc48KSH3D1OeAHFQhWpd8Fz8rLhTaD7t).
##   - [Download and Install GNU Emacs](https://www.gnu.org/software/emacs/download.html).
##   - [Installation instructions for Elpy, which is a python IDE for emacs](https://elpy.readthedocs.io/en/latest/introduction.html#installation).
##   - [PythonProgrammingInEmacs on the emacswiki has instructions for setting up other emacs python IDEs](https://www.emacswiki.org/emacs/PythonProgrammingInEmacs).
## - If you want to use a different IDE (not emacs), then you need to
##   come to office hours and show me that you can do interactive python
##   code execution in that other IDE. That means having one window with
##   python code, another window with python console, and you can use a
##   keyboard command to execute one or more lines of code at a time, and
##   immediately see the output in the console.
## 
## ## Instructions for conda
## 
## After [downloading conda](https://docs.conda.io/en/latest/miniconda.html), and before you activate an environment, you need to
## setup your shell for the first time.
## 
## ```shell-script
## conda init bash
## ```
## 
## That should put some code in your ~/.bash_profile, I had to copy it to
## my ~/.bashrc to get it to work on my setup (git bash in emacs shell on
## windows). After restarting your shell you should see a (base) prefix
## in your prompt, which indicates the name of the currently activated
## conda environment.  
## 
## After that, you can install python, with the same version that I use,
## via:
## 
## ```shell-script
##   conda create -n 2023-08-deep-learning
##   conda activate 2023-08-deep-learning
##   conda install python=3.11.4
## ```
## 
## That should create and activate a new conda environment with the
## required python version.
## After activation, that environment will be used for new python
## processes, looking for python modules, etc.
## 
## ## Python support in emacs
## 
## First of all, if this is your first time ever using emacs, please type
## C-h t (type h while holding down control, then let go of control and
## type t) to open the emacs tutorial. Read through the entire tutorial
## and do all of the exercises, which will teach you the most important
## keyboard shortcuts for navigating and editing code. Keep re-doing
## the tutorial every day until you remember all of the keyboard shortcuts.
## 
## To get python support in emacs I had to install emacs packages
## (elpy,conda). To do that first you need to put the following in your
## ~/.emacs file (which contains user-specific commands to run on emacs startup)
## to tell it to download packages from the MELPA
## repository,
## 
## ```elisp
## (require 'package)
## (add-to-list 'package-archives
##              '("melpa" . "https://melpa.org/packages/") t)
## ```
## 
## After putting the above in your ~/.emacs you need to restart emacs,
## then run M-x package-list-packages (M-x means hold down the option/alt
## key and type x) to see a list of packages you can install. Search for
## elpy and conda (maybe with C-s, meaning hold down control key and type
## s), mark for installation by typing i, then type x to install all
## packages marked for installation. Finally to tell emacs to use elpy
## with python code, and my conda environments, I put the following in my
## ~/.emacs file:
## 
## ```elisp
##   (elpy-enable)
##   (setq elpy-shell-starting-directory 'current-directory)
##   (setq conda-anaconda-home (expand-file-name "~/miniconda3"))
##   (setq conda-env-home-directory conda-anaconda-home)
## ```
## 
## Make sure to change the path above from "~/miniconda3" to 
## wherever you have installed miniconda, then again restart emacs.
## In emacs When editing a python file we can "activate" the conda
## environment via M-x conda-env-activate RET 2023-08-deep-learning RET then C-c C-z
## to get an interactive shell, then
## - C-RET to send line and step,
## - C-c to send highlighted region.
## 
## See
## https://elpy.readthedocs.io/en/latest/ide.html for more elpy key
## commands (sending code from python code files to the interactive
## shell), and https://realpython.com/emacs-the-best-python-editor/ for a
## nice tutorial about emacs and python.
## 
## ## FAQ 
## 
## On windows python not found error, or emacs can't find the python in
## your conda env, please fix by
## 
## ```elisp
##   (setq python-shell-interpreter "python");not "python3" !
## ```
## 
## Also if you have a space in your username, and you get an error about
## version "is" when you try conda-env-activate, then please try this fix:
