C/C++ Code generation for Alexnet without GPU

Hello,

I am a hardware guy with little knowlwdge on machine learning thing. I need pure C/C++ code for Alexnet , I am trying to generate the C/C++ code for the alexnet using MATLAB C Coder, but fail to do so.

*my pc does does not have GPU or NVIDIA drivers or libraries etc.

here is my entry function:

function out = alexnet_classify(in)

persistent mynet;

if isempty(mynet)
    mynet = coder.loadDeepLearningNetwork('alexnet', 'myalexnet');

out = mynet.predict(in);

end

I am getting the following error:

coder.loadDeepLearningNetwork is only supported for GPU code generation.

please help me

Hi Haroon,

Just a quick note, your if statement actually includes the assignment to out, since it requires the end statement. So it really looks like this.

function out = alexnet_classify(in)
persistent mynet;
if isempty(mynet)
    mynet = coder.loadDeepLearningNetwork('alexnet', 'myalexnet');
    out = mynet.predict(in);
end

Which means if you've already called this code once (and therefore mynet is now initalized) you won't get out assigned. I suspect you want

function out = alexnet_classify(in)
persistent mynet;
if isempty(mynet)
    mynet = coder.loadDeepLearningNetwork('alexnet', 'myalexnet');
end
out = mynet.predict(in);
end

This doesn't address your question (which is why I'm only marking it as a Comment).
