An application can't import the "urllib" module from the package "six". But I can import it from a test script in the same environment. Can't figure out why.
❯ nova
Traceback (most recent call last):

from six.moves.urllib import parse
ImportError: No module named urllib
But if I run a simple test script, it's just fine:
#!/usr/bin/python2
from six.moves.urllib import parse
foo = parse.urlsplit("http://foo.net/florp/blorp?blap=blork")
print foo
Here's the output:
❯ ./test.py
SplitResult(scheme='http', netloc='foo.net', path='/florp/blorp', query='blap=blork', fragment='')
Tried setting my PYTHONPATH explicitly, tried it under virtualenv... nothing..
Any ideas? (Sorry I'm not a Python programmer, so it may be something obvious).

I'm trying to run ocrmypdf which was installed via homebrew but am having issues with my local version of lxml (version 4.2.4):

from lxml import etree
ImportError: cannot import name 'etree' from 'lxml' ($HOME/anaconda3/lib/python3.7/site-packages/lxml/__init__.py)
If I open up a python shell, I'm able to import just fine:
>>> from lxml import etree
>>> etree.__file__
'$HOME/anaconda3/lib/python3.7/site-packages/lxml/etree.cpython-37m-darwin.so'
My pythonpath:
$HOME/anaconda3/lib/python3.7/site-packages:$HOME/Code_Repos/invoice2data//src:$HOME/Code_Repos/invoice2data//src/invoice2data:$HOME/anaconda3/lib/python3.7/site-packages:$HOME/Code_Repos/invoice2data
I'm not sure why the homebrewed package is not picking up the module file even though it says it's pointing to the same site-packages folder.
I'm using celery as task runner. It's been working fine with Python 2.7. Recently I upgraded my PC to Ubuntu 16.04 and it starts to give met the following error:
from uuid import UUID, uuid4 as _uuid4, _uuid_generate_random
ImportError: cannot import name _uuid_generate_random
Full call stack:
Traceback (most recent call last):

ImportError: cannot import name _uuid_generate_random
This seems rather strange to me. Currently my python version is:
Python 2.7.10
Was there some syntax change within the 2.7.x versions?
_uuid_generate_random has been removed and os.urandom is used instead.

It's a bug in an old version of kombu. Just upgrade and the error should go away.
pip install -U kombu
import weka.core.jvm as jvm
jvm.start()
data_dir = "C:/Data/Python/Weka/Data/"
from weka.core.converters import Loader
loader = Loader(classname="weka.core.converters.ArffLoader")
data = loader.load_file(data_dir + "logistic.arff")
data.class_is_last()
print(data)
I'm executing the above example code of weka python wrapper from their doc. So I'm sure that there's no problem in the code. All modules are installed. But the code is not working when it is run as script (by pressing F5 in IDLE). It is throwing the following error:
Traceback (most recent call last):
File "C:\Data\Python\Weka\weka.py", line 1, in <module>
import weka.core.jvm as jvm
File "C:\Data\Python\Weka\weka.py", line 1, in <module>
import weka.core.jvm as jvm
ImportError: No module named core.jvm
But the code works when I copy and paste it line by line to the IDLE command prompt. No idea why. Where did I go wrong?
Try changing the name of your file to something that's not the name of any of the module you're importing. For example change weka.py to myscript.py
I'm running into an issue with cx_Freeze when running a frozen application (works fine unfrozen).

from _sre import MAXREPEAT
ImportError: cannot import name MAXREPEAT
I'm on linux using a version of python 2.7.4 that I built from source, and importing _sre from a prompt works and I can access the MAXREPEAT constant.
This is usually down to cx_Freeze not pulling everything into library.zip and can be fixed by explicitly naming the module in cx_Freezes setup include list and is the solution to this similar question, but that hasn't helped here.
This _sre module seems weird.. there's no _sre file in the library.zip generated but from that error it seems like it can find it, however it can't import that symbol? Surely if the module wasn't there it would be a "No module named _sre" error. Or possibly a circular import but _sre stub doesn't have any imports.
What's odd is I can't seem to find the file either - is this module dynamically created when importing somehow?
find /usr/local/lib/python2.7 -name "_sre*"
doesn't return anything, and the imported _sre module doesn't have a __file__ attribute either, so I've no idea how to make sure it's included as it shows up as a built-in.
>>> import _sre
>>> _sre.__file__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute '__file__'
>>> repr(_sre)
"<module '_sre' (built-in)>"
This is similar to this question also which was asked recently, but in this case he was getting the error in the regular interpreter, however for me it's just in cx_Freeze.
edit
Running python -v does seem like it's a built-in, so I'm not sure why cx_Freeze can miss it, or how I'd fix it.

I encountered this problem when I just upgraded from ubuntu 12.10 to 13.04, and I fixed this by copying the /usr/bin/python to /path/to/my/env/bin/, and it worked just fine

_sre is a built in module, so there's no file to include for it, but it doesn't have a MAXREPEAT attribute in Python 2.7.3:
>>> import _sre
>>> _sre
<module '_sre' (built-in)>
>>> _sre.MAXREPEAT
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'MAXREPEAT'
My best guess is that your frozen copy somehow has the standard library .py modules from Python 2.7.4, but the compiled Python interpreter from 2.7.3 or an earlier version. I see you're working from /usr/local - maybe it's picking up an older version from /usr.
If all else fails, I got things running using this: http://www.kiwisoft.co.uk/blog/2014/08/17/fixed-importerror-cannot-import-name-maxrepeat
I had the same problem recently. Setting LD_LIBRARY_PATH=
solved the problem.
I was using cx_freeze 4.3.2 on my win 8 machine and it was always showing ImportError: cannot import name MAXREPEAT with cx Freeze if I ever tried to freeze a non built-in module, and once I downloaded version 4.3.1, it works, I'm able to freeze my all python 3.3 programs without any problem now.
I was having similar issues on windows 8 - was just a PYTHONPATH issue. check that PYTHONPATH exists by typing the following into a python session:
import os
os.environ['PYTHONPATH'].split(os.pathsep)
if you get an error set your PYTHONPATH using this approach..
