Matlab R2019 parpool out of memory

Hi, I am currently running Matlab R2019 and am using all of the code here. https://au.mathworks.com/help/audio/examples/acoustic-scene-recognition-using-late-fusion.html#d117e13537

However, i have run into this error. I really need to know how to overcome this issue of out of memory problem. Thank you.

Error using parallel.Future/fetchOutputs (line 347)

Internal problem while evaluating tall expression. The problem was:

One or more futures resulted in an error.

Error in parallel.internal.bigdata.ParallelPoolBroadcastMap>iRunOnAll (line 153)

[varargout{1:nargout}] = fetchOutputs(f);

Error in parallel.internal.bigdata.ParallelPoolBroadcastMap/synchronizeWorkerBroadcasts (line 115)

[newWorkerKeys, newWorkerValues] = iRunOnAll(@obj.getBroadcasts, keys);

Error in ...
