Appropriate build system for cpp returns of declared dtypes

[Matthew Gidden]

Hi all,

This is a bit in the weeds for me, and I'd enjoy some clarification.

I have a xdressed struct and a function that returns it:

h/cc:

class ArcFlow 
std::vector<ArcFlow> execute_exchange(Params& params, std::string db_path = "");

xdressrc:

stlcontainers = [
    ('vector', 'int'),
    ('vector', 'float'),
    ('vector', 'ArcFlow'),
    ('vector', ('vector', 'int')),
    ('map', 'int', 'float'),
    ('map', 'int', 'int'),
    ('map', 'int', 'bool'),
    ('map', 'int', ('vector', 'int')),
    ('map', 'int', ('vector', 'float')),
    ('map', 'int', ('vector', ('vector', 'int'))),
    ('map', 'int', ('map', 'int', ('vector', 'float'))),
    ]

However, when I call the function

from cyclopts.execute import Params, execute_exchange
from cyclopts.dtypes import xd_arcflow
obs = execute_exchange(params)

 

I get the following error:

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/nose/case.py", line 197, in runTest
    self.test(*self.arg)
  File "/home/gidden/phd/cyclopts/tests/test_execute.py", line 12, in test_null
    obs = execute_exchange(params)
  File "execute.pyx", line 314, in cyclopts.execute.execute_exchange (/home/gidden/phd/cyclopts/build/cyclopts/execute.cxx:7095)
NameError: name 'dtypes' is not defined

Any suggestions? I'd be happy to provide more data as requested.

Cheers,

Hi Matt,

This seems like it is a bug with the dtypes not being imported into execute.  The actual bug is probably in TypeSystem.register_classname().  I'll take a look.

Be Well

Anthony

HI Matt, 

From a clean build with the current xdress master and current cyclopts matser, and the following script:

from cyclopts.execute import Params, execute_exchange

from cyclopts.dtypes import xd_arcflow

params = Params()

obs = execute_exchange(params)

I see the following output:

scopatz@ares ~/t $ python temp.py

Clp0000I Optimal - objective value 0

Clp0032I Optimal objective 0 - 0 iterations time 0.002

This seems right to me...

Be Well

Anthony

[Matthew Gidden]

Ah yes, because I commented out the offending code to keep working.

[Anthony Scopatz]

So how do I reproduce this?

[Matthew Gidden]

Sorry, I was taking a moment to push to a new branch. You'll find it in cyclopts on the dtypes branch. Blowing away the build directory is required, of course.

A fix is in #216
