k4a_module did not found about pyk4a

[lpasselin]

Could you make sure the required modules are available during the initial install?

See specific instructions for windows in the readme. Adapt with your own paths and versions.

I have set those paths to my env :LINK="C:\Program Files\Azure Kinect SDK v1.3.0\sdk\windows-desktop\amd64\release\lib\k4a.lib"
Link-short="C:\Program Files\Azure Kinect SDK v1.3.0\sdk\windows-desktop\amd64\release\bin"
link1="C:\Program Files\Azure Kinect SDK v1.3.0\sdk\windows-desktop\amd64\release\lib"
link2="C:\Program Files\Azure Kinect SDK v1.3.0\sdk\windows-desktop\amd64\release"
link3="C:\Program Files\Azure Kinect SDK v1.3.0\sdk\windows-desktop\amd64\release\lib\k4a.lib"
link4="C:\Program Files\Azure Kinect SDK v1.2.0\sdk\windows-desktop\amd64\release\lib\k4a.lib"
link5="C:\Program Files\Azure Kinect SDK v1.2.0\sdk\windows-desktop\amd64\release\lib"
link6="C:\Program Files\Azure Kinect SDK v1.2.0\sdk\windows-desktop\amd64\release\bin"

And I have tried with quotes or without quotes, did not work either.

The last error is solved by accident, I just try import numpy first and then import pyk4a, it is worked then without change any path env.

But viewer.py get another error, shows below:

Azure Kinect Viewer v1.2.0 or Azure Kinect Viewer v1.3.0 both works well.
I am reading the source code in 'pyk4a.py', I cannot found how to "import k4a_module" in line2. There has no file named k4a_module.
And this module controls how to open sensor.

I am sorry, I am not used to windows paths.

It looks like it cannot find the kinect depthengine dll. Can you make sure it can be found?

[abbott1234]

I have thought about this, but I did not understand how did python link to depthengine dll, either did k4a.dll. Can you tell me which file and which line link them?
I have checked k4a.dll and depthengine_2_0.dll are in the same path. If it is path problem, k4a cannot be found either.

[lpasselin]

The Kinect azure needs the depthengine ddl at runtime. It can be installed with the regular installer. Sorry again, I am no good with windows paths.

@abbott1234 Have you solved it? how to solved it? I meet the same problem on win10.

@WestbrookZero did you find a solution to this problem?
