Removing import py_paddle.swig_paddle as swig_api from the first line confilicts with line 38:
tmp = swig_api.ParameterOptimizer.create(self.opt_conf)

===========
This is the error

python2.7/site-packages/paddle/v2/optimizer.py", line 38, in enable_types
tmp = swig_api.ParameterOptimizer.create(self.opt_conf)
NameError: global name 'swig_api' is not defined

I got this error, too.
Should we restore the first line import py_paddle.swig_paddle as swig_api ? @reyoung

• I think the problem is imported names are bound to the current scope, so an import inside a __init__() function binds to a local name only.
• Maybe one solution is importing the module again. The cost is inexpensive because module imports are cached globally in sys.modules.

I found this bug has been fixed by this PR #2907, so I close this issue. If there is any other problem, please feel free to reopen it.
