I am using Ubuntu 17.10

Python version: 2.7.14 Anaconda

I have Matlab R2017b installed. I also installed pymatlab-0.2.3

When I run following commands in python, I get "Segmentation fault (core dumped)" and ipython closes.

import pymatlab session = pymatlab.session_factory(options = 'nodesktop -nodisplay')

Also, when I debugged it using gdb, it gives following stack trace:

Starting program: /home/jsingla/anaconda2/bin/python test.py [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". Program received signal SIGSEGV, Segmentation fault. 0x00007ffff17f8029 in engOutputBuffer () from /usr/local/MATLAB/R2017b/bin/glnxa64/libeng.so

  • Did you make sure of requirements here: pypi.python.org/pypi/pymatlab? Especially cshell and path variable. Also, check numpy version Commented Jan 31, 2018 at 4:55
  • I have downgraded my numpy version to 1.3.0 and I am using python 2.7 You think I also need to go to Matlab2013a?? Because I used to have this working on Ubuntu 14.04 with latest numpy and Matlab, but now I have shifted to Ubuntu 17.10 and it stopped working. Commented Feb 1, 2018 at 0:51
  • Oh it might have something to do with ubuntu version. Generally, if you are not a Linux enthusiast and don't want to spend time debugging random issues you should use LTS version (16.04 in this case) Commented Feb 1, 2018 at 1:18
  • btw is your matlab launching without python? Try running matlab nodesktop -nodisplay on terminal Commented Feb 1, 2018 at 1:18
