Undefined function or variable 'replaceLayer'.

Why in some computers works and in other it does not works and they are the same version with the same toolboxes??

[Adam Danz]

replaceLayer() is from the Deep Learning Toolbox and was released in r2018b although there is mention of it in the r2018a release notes. Run ver() to print a list of available toolboxes and confirm that you have this toolbox. replaceLayer is a class method of layerGraph class.

Ahmed's answer moved here as a comment.

Same here it dose not work with me ?????+++++++

[Sai Bhargav Avula]

is it same error. As mentioned by Adam try checking the ver and availability of the toolbox

Also, did you try rehashing the toolbox?

if not

use the

rehash toolbox

The 'replaceLayer' function is not a standalone m function. It is a class method of 'layerGraph' class.

Since it is a class method, it is defined in the class file for 'layerGraph' and can be used only with particular layers.

For more information, please refer the 'Objective Functions' of 'layerGraph' at the documentation link mentioned below:

>> training

Undefined function or variable 'replaceLayer'.

Error in training (line 22)

Layer_Graph = replaceLayer(Layer_Graph, Feature_Learner.Name, New_Feature_Learner);

how can solve this problem??

[KH TOHIDUL ISLAM]

Add following lines:

Layer_Graph = layerGraph(Layer_Graph);

Layer_Graph = replaceLayer(Layer_Graph, Feature_Learner.Name, New_Feature_Learner);
