OpenCL platforms not found, inference renders poorly

Hi Marie!

AMD is always a fun one! I think installing some display drivers could help you:
 

cd /tmp
wget --referer http://support.amd.com https://repo.radeon.com/amdgpu-install/latest/ubuntu/noble/amdgpu-install_7.2.70200-1_all.deb
sudo apt install ./amdgpu-install_7.2.70200-1_all.deb
sudo apt update
amdgpu-install --usecase=graphics,opencl --no-32 --no-dkms

This should remove the OpenCL warning and also install some other (e)GPU packages, which should improve rendering.

Upon further investigation, I think our SDK is missing a tiny piece today (v1.5.3) for AMD chips. We’ll add it in a release soon. For now, please go into your sdk and open up the file operators/axstreamer/src/AxOpenCl.cpp, then

• In the get_order_preference function, add the following after the “NVIDIA”s line

} else if (preference == "amd") {
    return { "AMD"s };

• In the get_order_preference function, add “AMD”, to the return statement, expanding the vector
• In the build_cl_details function, rename the which_cl argument to cl_choice
• In the same build_cl_details function, add the following line at the beginning of the function

std::string which_cl = cl_choice ? cl_choice : "";

• In the same build_cl_details function, replace the line

std::string preference = which_cl ? which_cl : "auto";

with the line

std::string preference = which_cl.empty() ? "auto" : which_cl;

Then go back into your SDK and recompile these files with the command

make operators

Hope this helps!
