[Bindings] [MATLAB] save/load not supported #76

Open traversaro opened 9 years ago

traversaro commented 9 years ago

save/load is not supported.

As a first step, overload saveobj / loadobj to produce a clear warning message explaining the problem (this probably should be done at swig level).

In theory this should be possible by just modifyng the SwigRef.m that is the base class for all the SWIG Matlab classes, see the upstream issue at https://github.com/jaeandersson/swig/issues/59 .

dumb solution is to implement some simple matlab functions (save_idyntree, load_idyntree) which converts to a matlab matrix or structure and saves and then reads from a matlab matrix and structure and regenerates idynTree. I can implement one quickly if you think its a viable option.

Yes, this can be done in a transparent overloading the saveobj and loadobj methods. We need to understand how to do this in a way that it integrates with the swig code generation process (we cannot directly modify the generated code). Upstream issue for reference: https://github.com/jaeandersson/swig/issues/59

Any news on this topic? At the moment when I save in Matlab I have to take care of deleting or converting in matlab matrices all the the iDyntree structures, right? because I did not do that and now when I try to load my data I have the following error message:

Warning: Variable 'parametricEstimator' originally saved as a IncrementalParametricEstimator cannot be instantiated as an object and will be read in as a uint32.

Thank you for your help.

Mhhh so the load is crashing? I actually was able to load with no error, but then I crashed when using the object.

DiegoRomeres commented 9 years ago

In my case load is crashing directly. I am using Matlab2015b

traversaro commented 9 years ago

I think I know how to prevent the crash (but without a working load at the moment). I will push it in the afternoon.

DiegoRomeres commented 9 years ago

ok, thanks! But are there any workaround to been able to load and use the data afterwards?

traversaro commented 9 years ago

Which kind of variables? Perhaps we can write some specialized saveobj/loadobj methods for those objects that convert them to matlab objects for storing, as @naveenoid was proposing.

DiegoRomeres commented 9 years ago

Basically I am working with the repository 'semiparametric_matlab' and the data I save executing that repository give me the error when loading them back.

At the moment the warning message is complaining with the variables belonging from the class 'IncrementalParametricEstimator'. Clearly there might be other problematic variables as well that I do not see at the moment.

traversaro commented 9 years ago

Ok, so I should be able to replicate by running:

semiparametric_CADpar_script_generalization
save datasaved.mat
load datasaved.mat

Right?

DiegoRomeres commented 9 years ago

I am using the file:

semiparametric_CADpar_script_generalization

but looking to the other one it should be the same. (Anyway I will try also with semiparametric_estpar_script_generalization_repeated to see if the issue is also there)

raffaello-camoriano commented 9 years ago

Disclaimer: I have not read the whole conversation.

However, if you have to save large variables use the flag '-v7.3' of the save function, as follows:

save(filename,'dumvar','-v7.3');

It happened to me that large variables were not saved properly and led to a crash during loading.

Hope it helps.

traversaro commented 9 years ago

Ok, I will try with

semiparametric_CADpar_script_generalization
save datasaved.mat
load datasaved.mat
