Try to build API form: zed-python-api/src at master · stereolabs/zed-python-api · GitHub ,
try some other versions of CUDA-SDK-Python, but always get this Error.

Is there any way to solve this problem on Windows?

Hello and thank you for reaching us out,

A “simple” installation of the .whl will not work because Windows will not find the .dll file if you are using Python >=3.8.
To solve this :

  • Run python -m pip show pyzed
    You’ll obtain a directory.
  • Take the files sl_ai64.dll and sl_zed64.dll from C:/Program Files (x86)/ZED SDK/bin and copy them into the directory you obtained in the first step.
    Our get_python_api.py script does that already, but maybe yours failed for some reason.

Be aware that every python virtual environment needs its own pyzed installation and dll copies.
