Using code causes memory leaks.

[euijaebilly]

test.zip

this is minimum code for test

I'm going to create a streaming program using 'ibaiGorodo/pyKinectAzure'. Images need to be received from the device on a frame basis, but memory leakage occurs when images are received.

Memory leakage occurs again when using 'fromImage()' in pyside.

how can i solve this problem?

also I'm sorry for my poor English.

Hi,

I think it might be related with releasing the images and captures. I will have to check it.

How are you checking the memory leak? So that I can compare the results.

Thank you, Ibai

@ibaiGorordo and the test code in zip, has a method for checking memory usage, called 'memory_usage'

++ I add the 'get_combine_images()' in zip. sorry +++ i have to report my program before next Monday...it's emergency situation for me....help me...please

[ibaiGorordo]

I have not tested it, but looking at your code, I would say that the problem is that you removed the image_release and capture_release functions. Check the original example for reference, and let me know if that fixes the problem.

i edited code files in zip. camera.image_release(depth_image_handle) camera.image_release(color_image_handle) camera.capture_release()`

add this release code after get_images and...yes.... it's still leaking....

[ibaiGorordo]

Yes, I have been doing some testing and the memory leak only happens when running in a thread. I have tried to move the start of the device inside the run function, but it is still leaking. https://github.com/etiennedub/pyk4a/issues/79

I am not sure what the problem is. In the meantime, this repository might be better for what you are looking for, check the transformation example: https://github.com/etiennedub/pyk4a
