I just installed nltk and now it's not working, and I need assistance figuring out what's wrong.
I followed the install guide here [https://pythonprogramming.net/tokenizing-words-sentences-nltk-tutorial/][1]
Installed via pip
sudo pip install nltk
Then I launched python and downloaded all components
# python3
>>> import nltk
>>> nltk.download()
This worked, and it downloaded all the components(I chose all). After which I figured I was good to go. However, then I went to write my first script and it errored out on the 1st line which imported nltk.
Now when I open the python interpreter I get
# python3
>>> import nltk
"2016-03-02 04:34:03,630","regex.py","ERROR","There is a problem with your SQL query: SELECT regex, regex_id FROM regex WHERE type = 'date'"

I didn't get that error the 1st time I ran the import and executed nltk.download(), so I'm not understanding why I'm getting it now.
I've tried executing python as root and my normal user, and get the same error.
If I check my sys.path
>>> import sys
>>> sys.path
['', '/usr/lib/python3.4', '/usr/lib/python3.4/plat-x86_64-linux-gnu', '/usr/lib/python3.4/lib-dynload', '/usr/local/lib/python3.4/dist-packages', '/usr/lib/python3/dist-packages']
I can find nltk under /usr/local/lib/python3.4/dist-packages:
# ls /usr/local/lib/python3.4/dist-packages | grep nltk
nltk
nltk-3.1.egg-info
So it should be available. So why am I getting an error when importing now?

I have installed airflow with celery in my ec2 linux instance and airflow is working like a charm. Now when I made changes in its config file to use celery with airflow it is throwing the following error.

I have tried
export LD_LIBRARY_PATH=/usr/local/cuda-9.0/lib64 && sudo ldconfig
but i still get the same error,
Any suggestions would be really helpfull, Thanks in advance.
As pointed out by talonmies you're running a version of MXNet that depends on Cuda-9.2. It would be preferable to install Cuda-9.2 and update your library path to point to 9.2.
You can also also install MXNet for 9.0 using the pip package mxnet-cu90 if you were unable to update your Cuda dependencies.
I am trying to execute my python script which imports globally installed modules through pip. (Module like nltk)
Below is my code.
interpreter.execfile("/home/roy/eclipse-workspace/geospatial-analysis/src/main/resources/wordnet_util.py");
PyObject someFunc = interpreter.get("get_similarity");
PyObject result = someFunc.__call__(new PyString("Apple pie."), new PyString("Banana pie."));
Double realResult = (Double) result.__tojava__(Double.class);
I have added the path for python modules like,
import sys
sys.path.append("/usr/local/lib/python2.7/dist-packages")
But I get the following error,
*sys-package-mgr*: can't create package cache dir, '/usr/local/lib/python2.7/dist-packages/cachedir/packages'
Exception in thread "main" Traceback (most recent call last):
File "/home/roy/eclipse-workspace/geospatial-analysis/src/main/resources/wordnet_util.py", line 6, in <module>

Update:
I added sys.path.append("/usr/lib/python2.7") to the python file. It solved the above error. Now it can't find select module.

I have a project in progress. In this project I have to change some reports that they implement by XML code.
When I run my project with "python manage.py runserver"it runs truthfully and I can change my XML code and see the HTML files on chrome but when I want to see the PDF file of reports I get an error that says:
>"IndexError, your list is out of range"
so I start to debug it, in this process debugger said
"from django.db.models.constants import LOOKUP_SEP No module named constants".
this is whole trace back:

what should I do?
django==1.4
python==2.7.12
tastypie == 0.9.16
I can't change my django and python version.
This part of the traceback is showing you that the error is coming from django-model-utils.
File "/usr/local/lib/python2.7/dist-packages/model_utils/managers.py", line 13, in <module>
from django.db.models.constants import LOOKUP_SEP
The release notes say that support for Django 1.4 was dropped in version 3.0.
You could try installing an early version of django-model-utils, but really you should upgrade Django. Django 1.4 is years out of date and insecure.
