Getting rid of Dtype templating

[Martin Devera]

Hi,

the Dtype is specialized in caffe.cpp and _caffe.cpp as float. Thus there seems no

real need to have it as template parameter.

We could define Dtype using typedef which allows to remove almost all templates.

While I have no problems with metaprograming, it seems unnecessary here and

is cluttering both code and gcc error messages.

Is there any reason to not do it ? 

regards, Martin

I've seen this <Dtype> template thing all around the code. Does this mean I can change the default data-type that Caffe uses? If so, which data structures would be affected? Just weights, or also all the gradient back-propagation data-type would be changed?

Thanks,

Regards,

Alexandre

Yes you can. Mainly it changes Blobs and then all other places needed to accomodate

the change.

Templating allows you one extra thing over typedef, you can instantiate Net/Solver
for both double and float in the same code.

But IMHO it is not worth its complexity....

It allows you to change between using doubles and floats as your weights and inputs - I wouldn't call it "completely unnecessary".
