I am unable to import pyzed.sl. The error is ImportError: DLL load failed: The specified module could not be found, which has been previously reported. I am on windows 10 and tried on python 3.6 and 3.7 and get the same error in both versions.

Is GPU a requirement for any form of data collection using the zed2?

Hi @narayaba,

I am sorry you are facing issues with the SDK.

Here are a few things you can check :

  • It seems that you installed the Python API inside a virtual environment. Can you make sure that it is well activated when launching the script that uses the API ?
  • If it is the case, can you try installing the API outside the virtual environment ?
  • You can also try to install the API from the sources here
  • If none of the above works, can you visit this github thread and see if the suggested workarounds help with your problem

In order to use the ZED SDK, you indeed need an NVIDIA GPU. You can find the full requirement list on this page.

Thanks for your reply. How do you collect both the stereo recordings (left and right video), depth map and the sensor data via a gui all at the same time?

when i try to install the API from the github, the .zip downloaded file is corrupt.
