Online MatLab is not working properly

Online MatLab is not working properly since past few days. When I try to train a deep neural network, simulation starts intially but after some time it shows MATLAB has encountered an internal problem and needs to be closed. I am facing this issue since past 7-8 days now. Please someone tell me how this issue can be resolved and I request Mathworks technical support please try to resolve this issue as soon as possible.

Hi Debojit,

I understand that you are trying to train a Deep Neural Network and MATLAB Online is throwing an error "MATLAB has encountered an internal problem and needs to be closed".

The initial analysis suggest that this issue might have been caused due to MATLAB Online running out of memory while the script was executed. I would suggest you to modify the script to reduce the amount of memory required.

If the above workaround does not resolve your query, I kindly suggest you to try the following steps:

• Please confirm if you are using a supported browser. Know more about the browsers supporting MATLAB online here.
• Please clear the browser cache and reload MATLAB online.

Yes, I am using supported browser. I am using google crome. I tried by clearing browser cache and reloaded MATLAB online but still it is not working. Simulation starts initially but after some time again the same error happens. I have 2.3 GB space left in online MATLAB drive. Please help me by resolving this issue as soon as possible.

Hi Debojit,

You are refering to the memory available in your MATLAB drive whereas I am refering to the memory used by your script. You can inspect the current state of your code and modify it in the required manner through a series of steps that can be found here.

It is also possible that MATLAB online is referencing some functionality of the toolbox where there is a crash (example: exhaustion of any resource).

You can try the same work on MATLAB desktop and if the problem occurs again, you can refer the crash log or crash dump file to know the cause of problem. It can be read with a text editor such as Notepad, vi, or nano. You can locate the crash dump file here.

Additionally, I would recommend you to swap the browser that you are currently using with another from the list of supported browsers.

If the above steps still don't resolve your issue, it is likely that your MATLAB Online session data has been corrupted. I would suggest you to kindly try the below steps:

• Please log in to the following link: https://drive.matlab.com/files/ with your MathWorks Account credentials.
• On the upper-right, click on your name and select “Show Hidden Files”.
• Delete the ‘.session’ folder.
• Go to https://matlab.mathworks.com and try re-using MATLAB Online.

This is likely to resolve your issue.
