The input shape parameter should be the shape of 1 sample. In this case, it's the same (1, 28, 28) that corresponds to the (depth, width, height) of each digit image.
References¶ Python in a Nutshell¶ Python in a Nutshell, written by Alex Martelli, covers most cross-platform Python usage, from its syntax to built-in libraries to advanced topics such as writing C extensions. Python in a Nutshell The Python Language Reference¶ This is Python’s reference manual. It covers the syntax and the core semantics of the language. The Python Language Reference Python Essential Reference¶ Python Essential Reference, written by David Beazley, is the definitive reference guide to Python. It concisely explains both the core language and the most essential parts of the standard library. It covers Python 3 and 2.6 versions. Python Essential Reference Python Pocket Reference¶ Python Pocket Reference, written by Mark Lutz, is an easy to use reference to the core language, with descriptions of commonly used modules and toolkits. It covers Python 3 and 2.6 versions. Python Pocket Reference Python Cookbook¶ Python Cookbook, written by David Beazley and Brian K. Jones, is packed with practical recipes. This book covers the core Python language as well as tasks common to a wide variety of application domains. Python Cookbook Writing Idiomatic Python¶ Writing Idiomatic Python, written by Jeff Knupp, contains the most common and important Python idioms in a format that maximizes identification and understanding. Each idiom is presented as a recommendation of a way to write some commonly used piece of code, followed by an explanation of why the idiom is important. It also contains two code samples for each idiom: the “Harmful” way to write it and the “Idiomatic” way. For Python 2.7.3+ For Python 3.3+
Note: If you select an interpreter without a workspace folder open, VS Code sets python.pythonPath in your user settings instead, which sets the default interpreter for VS Code in general. The user setting makes sure you always have a default interpreter for Python projects. The workspace settings lets you override the user setting.
Next, read a tutorial and try some simple experiments with your new Python interpreter. If you have never programmed before, see BeginnersGuide/NonProgrammers for a list of suitable tutorials. If you have previous programming experience, consult BeginnersGuide/Programmers, which lists more advanced tutorials. If English isn't your first language, you might be more comfortable with a tutorial that's been translated into your language. Consult python.org's list of Non-English resources.
Thank you for sharing this with us. I found it to be of great benefit for me. # do you have a similar tutorial for RGB-D data? I know you add the extra channel but I suppose my struggle is even before that, with the per processing of the data. I recorded a ROS bag with the RGB-D data then I can extract the RGB in a folder and the D in another, then I get confused when trying to give it as an input to the convnet. (I struggle with the coding).
Once you have read a tutorial, you can browse through Python's online documentation. It includes a tutorial that might come in handy, a Library Reference that lists all of the modules that come standard with Python, and the Language Reference for a complete (if rather dry) explanation of Python's syntax.
Most (but not all) neural networks expect inputs to be in the range . You may see other scaling and normalization techniques, such as mean subtraction, but those are more advanced methods. Your goal here is to bring every input to a common range. Exactly which range you use may depend on:
Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.

Susan and I thought back to our first learnings with Python, and what we wish someone would have sat down and told us. We looked at various quick starts, such as one on Face API, and asked what someone would need to know to successfully walk through such a tutorial. And then we built a course.

This changes to the directory Python_Exercises under the Desktop folder (yours might be somewhere different). If you don’t know the location of the directory where you saved the file, you can simply drag the directory to the command line window. If you don’t know which directory your shell is currently running in use pwd, which stands for “print working directory”.
Installing Installing Python is generally easy, and nowadays many Linux and UNIX distributions include a recent Python. Even some Windows computers (notably those from HP) now come with Python already installed. If you do need to install Python and aren't confident about the task you can find a few notes on the BeginnersGuide/Download wiki page, but installation is unremarkable on most platforms.
When you are ready to write your first program, you will need a text editor or an IDE. If you don't want to use Thonny or something more advanced, then you can use IDLE, which is bundled with Python and supports extensions.

Python Koans¶ Python Koans is a port of Edgecase’s Ruby Koans. It uses a test-driven approach to provide an interactive tutorial teaching basic Python concepts. By fixing assertion statements that fail in a test script, this provides sequential steps to learning Python. For those used to languages and figuring out puzzles on their own, this can be a fun, attractive option. For those new to Python and programming, having an additional resource or reference will be helpful. Python Koans More information about test driven development can be found at these resources: Test Driven Development
For example, many new programers, use simple variable names like x and y. Do (err, try) not to do this. Instead, if you have two numbers - say 1 and 52 - use the variable names num1 and num2 instead of x and y. That way when others read your program, they can make an educated guess that num1 and num2 are probably numbers of some sort. Think of others when writing your programs, as well as your future self. Your future self will thank you.
Let's now run an example that's a little more interesting. In Python, packages are how you obtain any number of useful code libraries, typically from PyPI. For this example, you use the matplotlib and numpy packages to create a graphical plot as is commonly done with data science. (Note that matplotlib cannot show graphs when running in the Windows Subsystem for Linux as it lacks the necessary UI support.)
By making this requirement, CNN's can drastically reduce the number of parameters that need to be tuned. Therefore, CNN's can efficiently handle the high dimensionality of raw images.

This article covers how to initialize and configure debugging for Python with VS Code, how to set and validate breakpoints, attach a local script, perform debugging for different app types or on a remote computer, and some basic troubleshooting
