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.

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!
