To try it out, please follow the instructions at https://github.com/denizyuret/Knet.jl/tree/dy/1.1/tutorial and let me know if anything does not work. Thanks @jekbradbury for figuring this out.

@denizyuret: Thanks. one question about gcc compiler. How do I check whether I have gcc installed or not. By the way I have MS visual c++ compiler installed that works for cython. I have also numba installed but do not know which compiler it is using.
gcc --version
#OR
g++ --version
if you get an error you don’t have it installed. I believe you can install that compiler on MS as a standalone even after you’ve installed visual studio (where MS visual might have install cl ??).
Install C++ support in Visual Studio
I don’t have gcc installed.
When I run the 5th cell in ‘Julia is fast’. I get the following error.
IOError: could not spawn `gcc -std=c99 -fPIC -O3 -msse3 -xc -shared -o 'C:\Users\chatura\AppData\Local\Temp\jl_C7CA.tmp.dll' -`: no such file or directory (ENOENT)

Can’t I use MS visual c++ compiler and how? I have these components installed as part of visual studio. Sorry if this sounds silly but I am new to Julia and not a professional programmer.
C# and Visual Basic Roslyn compilers
MSBuild
Static analysis tools
Text Template Transformation
ASP.NET and web development
Visual Studio C++ core features
Visual C++ 2017 Redistributable Update
VC++ 2017 version 15.8 v14.15 latest v141 tools
Windows 10 SDK (10.0.17134.0)
i need to go through the colab notebooks myself to understand.
But the gcc compiler and Windows OS is not a Julia problem… that is c/c++ compilers and compatibility lameness. I don’t have access to Windows right now so I’m not sure what steps to take (or even if its worth the trouble trying to get gcc on windows 
). You could start here: http://mingw-w64.org/doku.php/download#mingw-builds
maybe someone else on this forum has better advice 
oh ahaha i should have looked at the notebook pane you were describing… I’m pretty sure you can just skip running much of that…
the example is building and compiling a C program and using that as an example of wrapping Julia and linking to it. From what I can see it’s just some expository code to show how easy it is for Julia to interop with C/C++
Having said that, I’ve never run Knet on Windows, only Linux and Mac, so I can’t speak to experience running Knet on windows.
But I’d say if you’re able to pkg install Knet and Pycall on your machine you’re likely good to go.
@Joshua_Bowles: Thanks. I plan work on other parts of the notebook.
