Gurobi is causing my python segfault on MacOS high sierra and anaconda 5.0

[Jixin Feng]

I just installed high sierra this week and updated Anaconda to the latest and gurobi stoped working. It still works on my Ubuntu 16.04 LTS though. 

I don't know it's just me or not

I am having the same issue on macOS.

 Anaconda3-4.4.0-MacOSX-x86_64.pkg was the version when we released Gurobi 7.5.1. We tested against it. 

The current Anaconda version 5.0.1 doesn't work for Gurobi 7.5.1 for Mac. It gets segfault. We are working with Anaconda to address it.

The workaround is to use other platform, like Windows or Linux, to use python 2.7 or to use older version like Anaconda 4.4.0.

Still not working for me with Gurobi 7.5.2. When do you think we can expect a solution for this problem? Thanks.

You could try to reinstall Gurobi 7.5.2 and the and the older Anaconda package (doing a clean installation), this should work. Or you could switch to python 2.7.
The problem was reported to the Anaconda developers but I have not heard of a fix yet.

Best, Michael

[Andrea Cassioli]

Any updates? I still get errors...

[Michael Winkler]

I just tried the newest version Anaconda 5.1 which comes with python 3.6.4 but it still segfaults.
Sorry I also do not have any news for a fix.

I am also trying to run gurobi 7.5.2 on python 3.6. I downgraded my anaconda to 4.4.0 but it still segfaults. Any updates on the fix? 

Thanks

Esra,

This was fixed with 8.0.0. I would recommend installing the latest Gurobi 8.0.1 on python 3.6
