Undefined function or variable 'sequenceInputLayer' when following Matlab Example with all extensions installed
显示 更早的评论
I'm trying to follow the Time Series Forecasting Using Deep Learning example from the Neural Network Toolbox.
I'm fairly certain that I have the correct packages installed. Image of my add-ons manager is below:
Following the example line for line, I get stock on the following command:
layers = [ ...
sequenceInputLayer(inputSize)
lstmLayer(numHiddenUnits)
fullyConnectedLayer(numResponses)
regressionLayer];
Matlab produces the following error:
Undefined function or variable 'sequenceInputLayer'.
Error in ForecastModel (line 27)
sequenceInputLayer(inputSize)
I cannot figure out why the function does not work as it is part of the installed Neural Network Toolbox. Do I need to do anything special to activate this toolbox within the current project or is there any other advice on how to get past this error?

James - which version of MATLAB are you using? According to sequenceInputLayer this function was introduced in r2017b. If your version is older than this, then this function will not exist.

Hello James,
As Geoff mentioned, the ‘sequenceInputLayer’ function is introduced since R2017b, so if you could upgrade to MATLAB R2017b or above version, this issue no longer exists.
For more information regarding this function please see: https://www.mathworks.com/help/nnet/ref/nnet.cnn.layer.sequenceinputlayer.html?searchHighlight=sequenceInputLayer
Thanks, Siwan

As Siwan Yang said, this function was introduced in release R2017b. If you're using a release that's older than that, you will not be able to use this function.
