Description

Does python api actually use CUDA? Any GPU usage in python drops the loop rate to half. ie. 60hz to 30 hz. While c++ code doesn't happen.

excertp from get_python_api.py of 4.1 SDK for u22, jetson, etc.

disp_str = "Detected platform: \n\t " + str(OS_VERSION) + "\n\t Python " + str(PYTHON_MAJOR) + "." + str(PYTHON_MINOR)
disp_str += "\n\t ZED SDK " + str(ZED_SDK_MAJOR) + "." + str(ZED_SDK_MINOR)
print(disp_str)

Steps to Reproduce

  1. Follow your seemingly outdated documentation: https://www.stereolabs.com/docs/app-development/python/install

...

Expected Result

Using depth map with PYthon should not decrease the frame rate 60 hz to 30 hz. Using C++ mem::GPU doesn't have it. I wonder if python API has the capability of it

Actual Result

as least simliar performance

Environment

OS: U22
CUDA:12.1
SDK:4.1

Anything else?
