Pip mixup of python versions - centos

I recently installed python 3.4 using this custom installation guide, the system had python 2.6 as default. Today i needed to install tldextract to python2.6
I did that using pip pip2.6 install tldextract but after i tried to import the module the import failed with this error.
Traceback (most recent call last):
File "process.py", line 12, in <module>
import tldextract
File "/usr/lib/python2.6/site-packages/tldextract/__init__.py", line 1, in <module>
from .tldextract import extract, TLDExtract
File "/usr/lib/python2.6/site-packages/tldextract/tldextract.py", line 70, in <module>
from urllib.request import urlopen
ImportError: No module named request
That seems to be the python3.4 version of tldextract since it is trying to find the request module in urllib. So i guess pip installed the wrong version of the module, how can i fix this? Or remove python 3.4 alltogether.

tldextract has the following code block in the source repo, and the line numbers match:
try: # pragma: no cover
# Python 2
from urllib2 import urlopen
from urlparse import scheme_chars
unicode = unicode
except ImportError: # pragma: no cover
# Python 3
from urllib.request import urlopen
So it looks like the Python 2 branch is throwing an exception for some unknown reason and it's failing over to Python 3. I would start by looking why that might be.

I am getting an error after importing pytest

i just installed pytest and i tried using it and it was giving me errors. i uninstalled it and installed it again and it was giving me the same errors as i tried importing it

ValueError: source code string cannot contain null bytes
can you please help me with what to do, or suggest another library just like pytest where i test my applications.
Thanks for your contribution
check if you installed pytest in the same pyenv you are using. Run pip list comand and check there is pytest there
It might be issue with environment in pyenv. Try to create new one. In PyCharm it is File -> Settings -> Project -> Python Interpreter -> Add

import ImageTk for google earth engine

I want to import ee.mapclient
but when I do this the following error is returned:
Traceback (most recent call last):
File "<ipython-input-16-5f312fd5c732>", line 1, in <module>
import ee.mapclient
File "C:\Users\Stefano\Anaconda2_2\lib\site-packages\ee\mapclient.py", line 43, in <module>
import ImageTk # pylint: disable=g-import-not-at-top
ImportError: No module named ImageTk
I am using anaconda and have installed pillow and PIL. Within my PIL folder in site-packages there is a file caled ImageTk.
When I do this:
from PIL import Image, ImageTk
everything imports fine, but for some reason ee.mapclient is not recognizing this.
A link to the python code used in mapclient.py can be found here:
https://github.com/google/earthengine-api/blob/master/python/ee/mapclient.py
Edit mapclient to put "from PIL import Image,ImageTk " in try block ,

Scipy and CX_freeze - Error importing scipy: you cannot import scipy while being in scipy source directory

I'm having trouble compiling an exe while using cx_freeze and scipy. In particular, my script uses
from scipy.interpolate import griddata
The build process seems to complete successfully, however when I try to run the compiled exe, I get the following message.
Traceback (most recent call last):
File "C:\Python27\lib\site-packages\cx_Freeze\initscripts\Console.py", line 27, in <module>
exec(code, m.__dict__)
File "gis_helper.py", line 13, in <module>

raise ImportError(msg)
ImportError: Error importing scipy: you cannot import scipy while
being in scipy source directory; please exit the scipy source
tree first, and relaunch your python intepreter.
After looking at scipy\ _init__.py file, there is the following:
if __SCIPY_SETUP__:
import sys as _sys
_sys.stderr.write('Running from scipy source directory.\n')
del _sys
else:
try:
from scipy.__config__ import show as show_config
except ImportError:
msg = """Error importing scipy: you cannot import scipy while
being in scipy source directory; please exit the scipy source
tree first, and relaunch your python intepreter."""
raise ImportError(msg)
I'm not entirely sure what is the problem here however although it seems that the erros is being thrown because there is a problem with the scipy config file. Possibly not being included in the build process. I'm quite a novice and hoping someone more experienced with generating build using cxfreeze can shed some light on this.
Incidentally, the scipy in use was installed from binaries here.
i have had the same issue. I added this code to the setup.py generated by cx_freeze:
import scipy
includefiles_list=[]
scipy_path = dirname(scipy.__file__)
includefiles_list.append(scipy_path)
Then, used includefiles_list as part of the build_exe parameter:
build_options = dict(packages=[], include_files=includefiles_list)
setup(name="foo", options=dict(build_exe=build_options))
I add the same problem and solved it using fepzzz method and including some missing packages:
additional_mods = ['numpy.matlib', 'multiprocessing.process']
includefiles = [(r'C:\Anaconda3\Lib\site-packages\scipy')]
setup(xxx, options={'build_exe': {'includes': additional_mods, 'include_files': includefiles}})
And using version 5.0.2 of cx-Freeze package, which solved an error when importing multiprocessing.process

Did redhat 6.5 recently break scipy?

I have a program I've been working on for ages. I haven't updated it since May 12th. When I run it today I get errors:
gsh#localhost 2014-05-08]$ ./kaplan.py
/usr/lib64/python2.6/site-packages/numpy/oldnumeric/__init__.py:11: ModuleDeprecationWarning: The oldnumeric module will be dropped in Numpy 1.9
warnings.warn(_msg, ModuleDeprecationWarning)
Traceback (most recent call last):
File "./kaplan.py", line 6, in <module>

File "/usr/lib64/python2.6/site-packages/scipy/interpolate/polyint.py", line 2, in <module>
from scipy import factorial
ImportError: cannot import name factorial
I'm running Redhat 6.5 workstation. I think redhat broke scipy sometime between May 12th and now. Does it look like I am correct, or is something else perhaps wrong?

ipython looks into a virtualenv of a different python verion for some reason

so i had ipython and it worked fine for a while. Then I used buildout to install ipdb.
The case is: ipython and python2.7 systemwide
naked-python virtualenvs in the home folder.
A plone instance in the home folder using virtualenv of python2.4 from the naked-python i mentioned
now i try to run ipython and i get

If you require any further info regarding the problem just tell me, i dont know wht else might be relevant...
(i run arch-linux)
Why do you have both python2.4 and python 2.7 libraries?? When ipython (v2.7) is importing doctest, it's moving into a python2.4 library. I'd inspect your PYTHONPATH environment variable, as well as sys.path i.e.
import sys, os
print '\n'.join( [p for p in sys.path ] )
print '\n'.join( [[ for
The order of this is important. Figure out why doctest is being imported from that python2.4 directory, and then remove that directory from sys.path. According to here, OverflowWarning is removed upon the upgrade to python2.5
