I have installed protobuf in Python 3.4 and i pushed the compiled code pb_x_pb2.py into python34 folder. When i enter import pb_x_pb2.py it shows the following error.
>>> import pb_interface_pb2

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

Smartsheet API beginner using python is in need of help
Hi, everyone. I am working on smartsheet API and am trying to follow the website to get some exercise first from https://smartsheet-platform.github.io/api-docs/#sdks-and-sample-code.
I have python 2.7.15 on Mac, so the first step I did was to download the pip folder, and type "pip install smartsheet-python-sdk" on my terminal to install pip. Then I used my .py file to test out the code, I ran the first line import smartsheet and there is an error already.
The message I got is below, any suggestions will be appreciated:

from enum import Enum
ImportError: No module named enum
enum module was added in Python 3.4 but you're on Python 2.7. The smartsheet platform claims to support Python 2.7 but it also requires the import of enum for it to work.
You can submit an issue to the project and hope that they fix it or upgrade to Python 3.4 and beyond.
Per a previous answer, the error is due to using Python 2, while enum was added in Python 3.4. However, there is a backport if you need to use Python 2 for some reason.
Simply install with pip install enum34. I tested smartsheet with the enum34 library using Python 2.7.16 and was successful.
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?
I am using Python 3.2.3. And I installed Jinja2.5 by downloading from this page: https://pypi.python.org/pypi/Jinja2/2.5.5
Then I used the setup.py to install it. This seemed worked like a charm. When I tested it by using this line:
from jinja2 import Template
I got the following error:

SyntaxError: invalid syntax
This is on my Raspberry pi with Raspbian installed. I don't know why this error occures, because the docs say Jinja2.5 and Python 3.2 are compatible.
Can anyone help me out?
Thanks in advance!
Try typing python --version if the reply does not say Python 3. something then your default python is python 2 and so does not support u'' for unicode strings.
If this is the case you need to install jinja2 by using pip3 install jinja2 and run your scripts with python3 scriptname.py.
Other than that see: Syntax error in jinja 2 library basically python 3.2 is no longer supported so the choice is pick another library or upgrade python.
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>
from pyshark.capture.live_capture import LiveCapture

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 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
