getting error: Can't reload '/usr/loca​l/MATLAB/R​2018a/bin/​glnxa64/li​bmwsl_grap​hical_clas​ses.so' when trying to use tabularTextDatastore

Hello,

I'm using Matlab R2018a on a ubuntu 18.04 server and when trying to use tabularTextDatastore i got the next error:

identifier: 'MATLAB:err_while_looking_up_function'
message: 'An error occurred while trying to determine whether "readData" is a function name.'
name: 'tabularTextDatastore'
line: 120

cause:

identifier: 'MATLAB:dispatcher:loadLibrary'
message: 'Can't reload '/usr/local/MATLAB/R2018a/bin/glnxa64/libmwsl_graphical_classes.so''

I checked /usr/local/MATLAB/R2018a/bin/glnxa64/ and the file is there....

We see this error as well. We already tried to reinstall Matlab and Ubuntu several times. We found that the issue does not occure when we only install Matlab and Matlab Coder without any Toolboxes. If Toolboxes, like Machine Learning Toolbox, are additionally installed the error is back.

We talked to the Tech support on this. They suggested to install openjdk-8-jre as it depends on the same packages.

Use

sudo apt-get install openjdk-8-jre

this solved my problem :)

after installing the jre again the problem is coming

Answer 2

I solved it by creating a directory named "exclude" within "/usr/local/MATLAB/R2018a/bin/glnxa64/" and puting "libmwsl_graphical_classes.so" in it

I was having issues using readtable in parallel on Linux (R2018a, Centos 7) - error about readData.

This fixed the issue, but I have no idea why. It would be nice to get some info from Mathworks on why this works.

Thanks! I also fixed a similar error.
