I am trying to run this example program - http://pysnmp.sourceforge.net/examples/1.x/snmpbulk.html
I am on Mac OS X, and I installed pysnmp by -
$ sudo /usr/local/bin/pip install pysnmp
Now when I run the program I get -
Traceback (most recent call last):
File "pysnmptest.py", line 2, in <module>
from pysnmp import msession
ImportError: cannot import name msession
UPDATE:
seems like pysnmp 4.x doesn't have msession, so I tried http://pysnmp.sourceforge.net/examples/4.x/v3arch/index.html
and now I get -
Traceback (most recent call last):

The webpage also says they have dependencies on third-party libraries -
Latest PySNMP releases (4.x and later)
depend on the following:
ASN.1 library for Python used for
handling ASN.1 objects Python
Cryptography Toolkit used for SNMP
message authentication and encryption
How do I install them? and would it better to install from the tarball from webpage directly?
which version of pysmnp did you install? The example you're trying to run seems to be suited for the 1.x version of pysnmp.
Here I've found examples for the newest 4.x version. Note they don't use msession so I guess it was removed.
EDIT: Looks like now you have to install pyasn1 from here...
I don't use OSX so I don't know what's the better method for installing software on it. On ubuntu I just did apt-get install python-pysnmp and the whole thing was installed.
pyasn1 has been depended by pysnmp. So you could just type:
from pyasn1.error import PyAsn1Error

I have tried all the import methods and upgrading the libraries but still I'm unable to get over this error. I have downloaded and installed all the nltk and corpus data programmatically and it is working in the python shell but i'm getting error.

Here's a pastebin to my code and imports..
Same error has been posted on github here. Use this instead to install textblob:
$ pip install -U git+https://github.com/sloria/textblob-aptagger.git#dev
Also, you should change from text.blob import TextBlob as tbto from textblob...
Works for me..
My issue is possibly similar to link
but thought I'd ask jic. I'm on osx and trying to use jedi-vim. I installed jedi using pip and then jedi-vim by cloning into the dir that my vim config uses for loading packages. this one for reference. When I start vim with a python program I get the "Please install Jedi if..." message. I cloned vim 74 and configured with +python and +conceal. After still getting the error I looked into the code and found it was an import error.
As an aside, this isn't the best help message. Better might be "Unable to import jedi. Have you installed Jedi?"
I tried import jedi from within vim, as :python import jedi

If this is a build issue, is there a good reference for building vim on mac?

Protobuf doesn't really support python 3.x. For the imported libraries, try pip install protobuf-py3, a python 3 port of the package. You can also run the 2to3.py script from the Pythonxx\Tools\Scripts folder on the generated file.
Another option would be to download the newest version of the sources, and compile them yourself. I believe that the newest version is mostly compatible with both 2.x and 3.x
I am trying to install pyshark in windows. [Python 2.6].
When I try to import pyshark in my python code.
I get the following error -
**Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pyshark\__init__.py", line 1, in <module>

import lxml.objectify
ImportError: DLL load failed: The specified procedure could not be found.**
looks like the lxml.objectify is not available, but I have installed lxml.
If you're on Windows (and it looks like you are), download and install lxml from Christoph Gohlke's Python Extension Packages.
Then you should be able to use pyshark.
Recently, I tried different packages for Python. You can try firstly pip install xyz, if it is not workable then swift to Anaconda or miniconda and write conda install xyz in cmd.
I use ropevim perfectly in Ubuntu system,
but i got lots of lots error.
i use homebrew to install macvim and python
and follow the tutorial.
http://wizardmode.com/2012/07/mountain-lion-and-homebrew-vim-importerror-no-module-named-site/
I wander know is the ropevim are very buggy or not practical in mac os system.
because the discussion is not popular?
or is there any better solution in vim for Python on mac os?
Thanks very much...it's annoying me lots of time

I encountered a very similar stack trace when setting up some vim extensions from this page http://sontek.net/blog/detail/turning-vim-into-a-modern-python-ide
I believe the problem comes from incompatibilities between 'macport' and native python libraries, and that the native version of vim tries to pull from both.
I ultimately resolved my problem by using macport to install vim with python27 variant.
sudo port install vim +python27
The default configuration of macport's vim is without 'python' enabled.
