Getting error while executing audioFeatureExtractor

Hello sir/madam,

I am getting below error, as I was trying to execute audioFeatureExtractor, kindly help to resolve this error. in the previous matlab trail it was working. I have downloaded new trail and iam getting this berror and I was training it to yamnet plz check

Unable to resolve the name matlabshared.fusionutils.internal.setProperties.

Hi Hema,

I suspect you have some kind of install issue.

A few things to try:

• Execute rehash toolboxreset
• Execute this command and le t me know what you get:

matlabshared.fusionutils.internal.setProperties

• In the toolstrip, under preferences->general, uncheck the 'Enable toolbox path cache' check box
