Hello,
I'm getting this warning message when I'm attempting to load my SeriesNetwork model in matlab. I believe because of this warning, I am also unable to use codegen on a simple function I've created. Both coder.loadDeepLearningNetwork function (that I am using for my function when I use codegen to create a C++ executable) and the simple load function, both which are loading in a .mat file that contains only the net, give the same error of:
Warning: While saving an object of class 'SeriesNetwork':
Dot indexing is not supported for variables of this type.
I'm not sure where the dot indexing is occuring or how to resolve this issue. I need to fix the warning or else my codegen won't fully run. Let me know if I need to further explain anything else.
More details on the codegen error:
Warning: While loading an object of class 'SeriesNetwork':
Dot indexing is not supported for variables of this type.
> In dltargets.internal.loadMatObjImpl
In coder.loadMatObj

??? Dot indexing is not supported for variables of this type.

Hi Yusra,
From the error message thrown it seems to me that the MATFile storing the network is likely corrupted. Can you try resaving the network to a new MATFile and see if loading the network using "load" in MATLAB works or not. If "load" itself fails, then codegen will also fail since during codegen the network is also loaded into MATLAB.
Also, are there any custom layers in the network that you are trying to load. It maybe that the custom layer is not on the PATH and hence loading the network fails. In that case, add the custom layer to the PATH using addPath and then try to load the network.
Hope this helps!
