I recently installed openalpr on my mac using brew install openalpr with success. I would like to use the openalpr library with python 2.7 but I am having difficulty binding the two and could use some help.
I currently get the following in my projects file location:
Python 2.7.11 (default, Jan 22 2016, 08:29:18)
[GCC 4.2.1 Compatible Apple LLVM 7.0.2 (clang-700.1.81)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from openalpr import Alpr
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named openalpr
>>>
When I move to /usr/local/Cellar/openalpr/2.3.0/lib/python2.7/dist-packages/openalpr
The import works. How can I bind this library? Thanks
EDIT: I think I've seen that running the setup.py for openalpr is how you bind but I have no idea where to find it in my file system.
I had to do the following command:
echo /usr/local/opt/openalpr/lib/python2.7/dist-packages/ >> /usr/local/lib/python2.7/site-packages/openalpr.pth

I have Python 2.7.5 in rhel-7x. I have tried to import Tkinter but i got a error as below
`Python 2.7.5 (default, Oct 11 2015, 17:47:16)
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2

>>> import Tkinter
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named Tkinter`
Can you help me to install Tkinter module in rhel-7x with python version 2.7.5 ? Thanks in advance...
In which redhat are you ? Enterprise, fedora, centOs ?
yum install tkinter
You need to enable the optional rpm repo in /etc/yum.repos.d/redhat.repo.
You may find the section like below in the file, and set enable=1.
[rhel-7-workstation-optional-rpms]
...
enabled = 1
After enabling the optional, the command sudo yum install tkinter may work as it does for me.
When I try to import vtk, it doesn't work.
I tried this method (build the vtk with cmake and update environment variables - except the "Post installation tasks"), but I still have :
$python
Python 2.7.6 (default, Sep 9 2014, 15:04:36)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin

>>> import vtk
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named vtk
I tried before that
sudo brew install python-vtk
but it returns :
Error: No available formula with the name "python-vtk"
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
Error: No formulae found in taps.
How can I import vtk in my Python code on my Mac computer without problem ?
Use the darwin dmg file here;

I have followed the steps in the website below, and installed everyhting for MySQLdb.I am using Xampp for the database and I have linked the mysql_config to the xampp mysqlconfig.
http://www.tutorialspoint.com/python/python_database_access.htm
However, after everything was installed and when I try to import it says:
Python 2.7.5 (default, Mar 9 2014, 22:15:05)
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin

>>> import MySQLdb

Thanks ahead of time for all your help!
What solved my problem is:
Installed homebrew from this website:http://brew.sh
Installed mysql using brew:
brew install mysql
Followed this website to build and install python MySQLdb:http://www.tutorialspoint.com/python/python_database_access.htm
After all of that everything is perfectly working.So if anyone is having trouble with MySQLdb on a Mac, then just follow those instructions. I hope this helps.
I have mac os x 10.9. I downloaded opencv-python using homebrew and I have both the python 2.7 and python 3.4 versions off of the main python site, downloaded the usual way with macs. I need to use opencv, but they do not have a download package for macs so I used homebrew:
brew tap homebrew/science
brew install opencv
When I type python into the terminal, and then type import cv, I get a segmentation error and python quits unexpectedly. The same thing happens in IDLE. For python 3.4, I get a no module error. Here it is:
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 00:54:21)

>>> import cv

>>> import cv
Segmentation fault: 11
and then it quits unexpectedly. Does anyone know what is going on? Frankly I have spent way too much time on this opencv issue and am finding it very frustrating. Thank you!
Chris Muktar pointed in this thread that the problem is caused by the conflict between the system Python and brewed Python. Following that idea, I resolved this issue by removing the system python and re-installing opencv:
$ cd /usr/bin
$ sudo mv python python.bak
$ brew uninstall opencv
$ brew install opencv
I am trying to run python in an Apache WS in a linux RHEL x86_64.
After Install and configure Python2.5 and Apache, I install Oracle Instant Client (basic and sdk) in a by an .rpm file withou any problem.
oracle-instantclient-basic-10.2.0.4-1.x86_64.rpm
oracle-instantclient-devel-10.2.0.4-1.x86_64.rpm
I set the envoirment variables
export ORACLE_HOME=/appl/paths/instantclient_10_2
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
Then install cx_Oracle by an .rpm file too and again withou any problem.
cx_Oracle-5.0.3-10g-unicode-py25-1.x86_64.rpm
When I try to import cx_Oracle in python I got the message
Python 2.5.2 (r252:60911, Jul 1 2010, 17:47:36)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2

>>> import cx_Oracle
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /appl/paths/python2.5/site-packages/cx_Oracle.so: undefined symbol: OCIDBShutdown
I google for answers without success. Any tip?
The problem was in the ORACLE_HOME, there was a misspelling on it
I solved the same problem by installing an older version of cx_Oracle (4.3.1 instead of 5.1.2). Just for future reference.
