k4a_module did not found

[abbott1234]

When I was running viewer.py
GOT AN ERROR :Traceback (most recent call last):
File "viewer.py", line 1, in
import pyk4a
File "D:\ProgramData\Anaconda3\envs\pose\lib\site-packages\pyk4a_init_.py", line 2, in

File "D:\ProgramData\Anaconda3\envs\pose\lib\site-packages\pyk4a\pyk4a.py", line 2, in
import k4a_module
ImportError: DLL load failed: cannot find the specified module

fristly, I think it is the SDK vision problem, so I was trying to find vision1.2 SDK. but when I was installed vision1.2 it did not worked either.
I guess it is the linking problem, but I did not know how to use it

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.

[abbott1234]

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.

[abbott1234]

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.

[lpasselin]

@WestbrookZero did you find a solution to this problem?
