I am writing a CNN code for an image classification problem and I want to use global average pooling. I found the globalAveragePooling2dLayer in this link: https://www.mathworks.com/help/deeplearning/ref/nnet.cnn.layer.globalaveragepooling2dlayer.html
However, when I try to use it within my Layers array, I get the following error:
Undefined function or variable 'globalAveragePooling2dLayer'.
Error in cnn_trial (line 64)
globalAveragePooling2dLayer
I have the Neural Networks toolbox and I have used the average pooling layer before. How can I fix this issue?
Thank you,

This layer is available from version R2019b and onwards. Which version are you using ?

Hi Nour,
The globalAveragePooling2dLayer was introduced in R2019b. As you are using R2018a, you are facing the Undefined function error.
You cannot use tools from a recent release in an older release. Either, you can upgrade to a new release or you can install the newer version alongside the your older R2018a version.
Hope this helps.
