Can python use the matlab engine for batch job processing: matlab.eng​ine.Engine​Error: Transport stopped

I need to use matlab in python, so I used eng = matlab.engine.start_matlab(). The program needs to be implemented in the batch job system of the supercomputer, running multiple jobs at the same time, and the following errors will occasionally occur as a result of the operation

Traceback (most recent call last):

File "mainDSICE.py", line 497, in <module>

eng = matlab.engine.start_matlab()

File "/data/group1/z44167z/Python3.8.2/lib/python3.8/site-packages/matlab/engine/__init__.py", line 119, in start_matlab

eng = future.result()

File "/data/group1/z44167z/Python3.8.2/lib/python3.8/site-packages/matlab/engine/futureresult.py", line 67, in result

return self.__future.result(timeout)

File "/data/group1/z44167z/Python3.8.2/lib/python3.8/site-packages/matlab/engine/matlabfuture.py", line 87, in result

handle = pythonengine.getMATLAB(self._future)

matlab.engine.EngineError: Transport stopped.

From the results of the last run, this error occurred 2 times out of 60 jobs.

Can the matlab engine perform batch jobs, and what causes this problem? please help me.

I have the same problem. It doesn't happen all the time but every few jobs it happens, my solution has been to implement a try-except in python to save those cases. But it would be great if someone knows why this happens.

Hi,

I had faced a similar issue. It might be a bug, as upgrading the MATLAB to latest version had solved this issue.

I hope this helps!
