Closed sinashm closed 4 years ago

sinashm commented 4 years ago

Describe the bug

In the new version of opengen, when I do import opengen I am getting following error:

import opengen as og Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python2.7/dist-packages/opengen/init.py", line 2, in import opengen.builder File "/usr/local/lib/python2.7/dist-packages/opengen/builder/init.py", line 1, in from .optimizer_builder import * File "/usr/local/lib/python2.7/dist-packages/opengen/builder/optimizer_builder.py", line 278 def __construct_mapping_f1_function(self) -> cs.Function: ^ SyntaxError: invalid syntax

@sinashm it seems that you're using Python 2.7. Can you try again with Python >= 3.5? It would be good to use virtualenv.

sinashm commented 4 years ago

@alphaville It doesn't give me the same error in the python3. I have some connection refused problem, but I will have a look into it. ConnectionRefusedError: [Errno 111] Connection refused Does it mean that Opengen will not support python 2.7 anymore?

alphaville commented 4 years ago

@sinashm That's correct, we do not support Python 2.7 anymore (see the installation instructions of OpEn). It was announced earlier this year that Python 2.7 would retire in September if I remember well. I see now there's an extension till the end of this year, but it will soon be deprecated.

Can you submit your connection issue as a separate one?
