No GPU detected, ZED2 #522

Closed anthogd closed 4 years ago

anthogd commented 4 years ago

Dear all,

I am trying to record the images coming out of the cameras as well as some other topics that could be published. However I do not have a NVIDIA graphics card and when launching the zed2.launch file I have the following error

[ZED]ERROR: sl::Camera::Open has not been called, no Camera instance running.
in Camera.cpp : void sl::Camera::close() at 158 : cuda error [100]: no CUDA-capable device is detected.
in Camera.cpp : void sl::Camera::close() at 202 : cuda error [100]: no CUDA-capable device is detected.
No NVIDIA graphics card detected. Install an NVIDIA GPU, CUDA and restart your computer after completing installation.
[ INFO] [1581587820.095641605]: ZED connection -> NO GPU DETECTED

The topics being published are : /diagnostics /tf /tf_static /zed2/joint_states

Are these the nominal topics being published or am I missing something?

Thanks, Anthony

Hi @anthogd the ZED SDK requires an Nvidia card to run since it is based on CUDA. You cannot start the ZED Wrapper node on a system that does not support CUDA.
