how to install deep learning toolbox in MATLAB R2018b?

I want to use biLSTM and other tools of deep learning in MATLAB R2018b, is there any way without using new version of MATLAB to get the specific toolbox as the newer version is taking more time than expected for my system.

Toolboxes created by Mathworks are version specific. You can install the R2018b version of the Deep Learning Toolbox using the Add-Ons Explorer.

The bilstmLayer function was introduced in R2018a, and had some updates made to in in R2019a (see here).

You can also consider reporting performance issues here: https://www.mathworks.com/support/contact_us.html

what should i tag name to find bilstm as whenever I am writing deeplearning or bilstm, it's directly showing 2023 version function?

Perhaps I misunderstood your question. Can you share a link to what you are trying to use?

I have installed deep learning tool using add ons, but still it is showing BiLSTM not found.

Input data successfully read.

Time Series data divided to 80% Train data and 20% Test data

Time Series data prepared as suitable LSTM Input data.

LSTM architect successfully created.

Error on Training LSTM Network

Reference to non-existent field 'BiLSTM'.

Error in TimeSeriesPrediction>EvaluationData (line 477)

data.BiLSTM.TrainOutputs = deNorm(data.seriesdata,predict(data.BiLSTM.Net,data.XTr,'MiniBatchSize',opt.miniBatchSize),opt.dataPreprocessMode);

Error in TimeSeriesPrediction (line 50)

[opt,data] = EvaluationData(opt,data);

I am getting this error when I am running code, and when I am looking for app deep learning , the status of app is installed.

oh thanx, got it instead environment 'gpu' i have changed it into cpu. Now its working fine. Thankyou
