Error with modules built for Python 3.5

[aalavandhaann]

Dear saviours,

Firstly, I want to thank you for this wonderful library. Seems robust and should make the lives of plethora of python developers in our world a good one. I tried generating the library using the examples but with one tiny change in the Cmakelists.txt i.e., setting the version of python from 2.7 to 3.5

#set(PYBIND11_PYTHON_VERSION 2.7)
set(PYBIND11_PYTHON_VERSION 3.5)

The library was sucessfully built inside the build directory with the test_classes.py and test_functions.py contained in the same directory. When I run the examples as shown in the README.md

python3 test_classes.py

I get this error (not able to import the module)

Traceback (most recent call last):
  File "test_classes.py", line 2, in <module>
    import pyshapes.geometry
  File "/home/ashok/libraries/cppwg/build/pyshapes/geometry/__init__.py", line 2, in <module>
    from _pyshapes_geometry import *
ImportError: No module named '_pyshapes_geometry'

I checked if those modules are available and indeed the pyshapes directory can be seen with the subdirectories containing the relevant so files. I am using Ubuntu 16.04 with the GNOME flavor on an AMD machine.

Any ideas where this is going wrong?

Okay, after copying the so files and dropping them directly under the folder where test_functions.py and test_classes.py exist (directly under the build directly) the tests work okay

But it throws this warning

test_functions.py:10: DeprecationWarning: Please use assertTrue instead.
  self.failUnless(c == a + b)
.
----------------------------------------------------------------------
Ran 1 test in 0.000s

OK

Is this something to worry about?

Hi, unfortunately I wasn't able to support this package when you had your questions. Python 3 wasn't supported or tested at the time, however it is enabled by default now. The ImportError is just due to a change in relative vs. absolute import behaviours between Python 2 and 3.
