PyNuitrack Crash

Nuitrack SDK
1

Hi,

What is not working:

I tried to use PyNuitrack to record human skeleton. Once I enabled CNN_HPE, the example code crashed with the following warnings:

WARNING: Can’t load library: %NUITRACK_HOME%/middleware/plugins/openvino_gapi_preproc.dll WARNING: Can’t load library: %NUITRACK_HOME%/middleware/plugins/openvino_intel_cpu_plugin.dll WARNING: Can’t load library: %NUITRACK_HOME%/middleware/plugins/openvino_ir_frontend.dll WARNING: Can’t load library: %NUITRACK_HOME%/middleware/plugins/openvino_c.dll WARNING: Can’t load library: %NUITRACK_HOME%/middleware/plugins/libcnn-hpe.dll WARNING: Can’t load library: %NUITRACK_HOME%/middleware/plugins/libcnn_hpe_plugin.dll

Meanwhile, the RegressionSkeletonization does not work.

What is working:

I also tried with the GUI, the Nuitrack AI GUI works fine with skeletonization and csv recorder
meanwhile, nuitrack_sample.exe also works fine with skeletonization

Here are the platforms I am running on

Windows 11
Python 3.10.16
IntelRealsense L515
Nuitrack v0.37.24

Could anyone help me with this? Thanks!

Best regards,
Changhan

Hello @portraitcc

It looks like NUITRACK_HOME variable is not set or open vino library conflict.
Could you check the value in the NUITRACK_HOME variable in python print(os.path.isdir(os.getenv("NUITRACK_HOME")))?
Do you have other packages or programs using open vino? Could you send me the pip3 freeze log?

Hi @irakli ,

Thanks for your reply.

print(os.path.isdir(os.getenv(“NUITRACK_HOME”)))
True

I am pretty sure that the NUITRACK_HOME is properly set.

Attached please find the freeze log

Hi,

I rolled it back to python 3.8. Then the problem is gone.
So the problem becomes version specified. Please take a look at the python3.10.16. Thanks!

Best regards
