error importing Pandas in python-3.4 unix environment - undefined symbol: pyobject_cmp -


i using pandas version 0.16.1 , working fine wanted update pandas version 0.16.2 uninstalled , reinstalled using

pip uninstall pandas pip install pandas 

the installation seemed work fine. however, when attempt import pandas

import pandas 

i error:

traceback (most recent call last): file "path_to_python/python3.4/site-packages/pandas/__init__.py", line 7, in <module> pandas import hashtable, tslib, lib importerror: path_to_python/python3.4/site-packages/pandas/hashtable.cpython-34m.so: undefined symbol: pyobject_cmp  during handling of above exception, exception occurred:  traceback (most recent call last): file "<stdin>", line 1, in <module> file "path_to_python/python3.4/site-packages/pandas/__init__.py", line 13, in <module> "extensions first.".format(module)) importerror: c extension: path_to_python/python3.4/site-packages/pandas/hashtable.cpython-34m.so: undefined symbol: pyobject_cmp not built. if want import pandas source directory, may need run 'python setup.py build_ext --inplace' build c extensions first. 

however:

cd path_to_python/python3.4/site-packages/pandas/ python setup.py build_ext --inplace 

doesn't work either there no setup.py found. error is:

fatal python error: py_initialize: can't initialize sys standard streams attributeerror: 'module' object has no attribute 'openwrapper' aborted (core dumped) 

any advice or insight going wrong appreciated!

update:

i tried install source downloading package:

python setup.py install python setup.py build_ext --inplace 

this time second command generated lot of output , completed. however, still same error when try import pandas

in case interested, unable pandas install pip switched using miniconda , installed , worked fine.
