The fix here was moving some files (include folders and .lib files) around from my kinect install (Azure Kinect SDK v1.2.0) to my Python37 directories (include and lib folders)!
Now, I have this error:

Still stuck on this -- I can see I've got some issue pointing files to the right files (although I cannot find anywhere where these functions are actually defined in the Kinect sdk, only declared in k4a.h) and have been editing my Path and PYTHONPATH and copying files into different locations to try and resolve, but no luck. Based on my errors earlier and the requirements in the k4a.h file, I think I may not have my .dll files in the right location or linked correctly. Any ideas/advice?! Thank you!

Do I need to re-compile the SDK from scratch on my computer? Or is having it installed (and able to run k4aviewer) enough?
from py-k4a.
Sorry, I only tried this on Linux, so I'm not sure about linking on Windows.
You're definitely having linker errors which means that for some reason the linker can't find the .dll for the Kinect for Azure library...
I have to admit, I don't know very much about how to build things on Windows. I'll see what I can do but I can't promise anything. Apologies!
from py-k4a.
I think I solved it! For what it's worth I was facing two issues: 1) I needed quotes in my LINK environmental variable (oof!) and 2) I was pointing to the wrong k4a.dll; needed the one in the "release" folder. I will try to write up more in detail what I did to compile on Windows and post here soon; just wanted to let you know I got it compiled. (I did not need to recompile the full c-build on my machine, just point to the correct files in my already installed SDK.)
from py-k4a.
Here's a rough outline of the process I used to set up on two different windows machines:
-- had Python 3.7 installed and working
-- had Azure Kinect Sensor SDK installed (with Microsoft Installer), k4aviewer.exe works
-- had VS2019 with C++ desktop development tools, C++/CLI, and most recent Windows 10 SDK installed
-- environmental variables CMAKE_C_COMPILER pointing to cl.exe inside VS2019
-- environmental variable LINK pointing to k4a.lib, with quotes! (because t he defaultAzure SDK folder name has spaces in it)
-- added sdk\include to user Path
-- added Python DLLs folder to user Path
-- copied k4a folder of sdk to Python include folder
-- copied k4a.dll and k4a.pyd to Python DLLs folder
-- copied k4a.lib to Python lib folder
python setup.py build
python setup.py install
The details were different on both computers, but hopefully this helps anyone else trying to install!

Cool, glad you got it working. I'd love a Pull Request (PR) for a Markdown file describing how to do this.
It's easier for someone to find the docs that way rather than looking at the issues.
Thanks!
from py-k4a.
For the file named k4a.pyd which I did found in my sdk folder. And the copied files most of they have more then one in sdk folder
And the error same as the last error you meet. I have tried add quotes and k4a.dll is the one in release folder
from py-k4a.
The above error is solved, but when am running example.py, it request k4a module. I did not found k4a.pyd in the sdk folder either. Did 1.3sdk delete this file?
