i am using windows 64 bit python 2.7.3 32bit and pythonocc 0.5 all in one
What is the solution to the above probelm?
If you have 64 bit python, it can struggle to load 32 bit Dll's.
Try this link
I recommend getting a 32 bit distribution of python, this should solve your problem
Install pythonocc 0.6 from this link http://code.google.com/p/pythonocc/ this should work fine
At the following link you can find pythonOCC for Python 2.7:

Ah, yes, back to the joy of installing GDAL.
This time, I need to install GDAL 2.1 for Python 2.7, 64-bit, on Windows 7. I used these installers for the Python bindings and GDAL core, and set the appropriate path variables. I am using Numpy 1.10.4.
In the Command Prompt:
gdalinfo --version
> GDAL 2.1.0, released 2016/04/25
In Python:
>>> Python 2.7.11 ... MSC v.1500 64 bit(AMD64) on win32
from osgeo import gdal
gdal.__version__
>>> '2.1.0'
So far, so good. But, it fails to find _gdal_array.pyd when trying to read a dataset to a Numpy array:
ds = gdal.Open("test.tif")
data = ds.ReadAsArray()
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
ds.ReadAsArray()
File "C:\Python27\lib\site-packages\osgeo\gdal.py", line 1825, in ReadAsArray
import gdalnumeric
File "C:\Python27\lib\site-packages\osgeo\gdalnumeric.py", line 1, in <module>
from osgeo.gdal_array import *
File "C:\Python27\lib\site-packages\osgeo\gdal_array.py", line 26, in <module>
_gdal_array = swig_import_helper()
File "C:\Python27\lib\site-packages\osgeo\gdal_array.py", line 18, in swig_import_helper
import _gdal_array
ImportError: No module named _gdal_array
Has anyone been able to install GDAL 2.1 successfully on a 64-bit system?
If you downloaded from source and installed numpy just after the build. You need to rebuild e reinstall the gdal/swig/python.
Hope it helps!
I have read many posts about problems but none of them can solve mine. Although I have been following this blog exactly I still get this error when I try to run one of the example src python files:

Unfortunately I am not familiar with the /.bash_profile but what is posted in the link I added at the end.
Can please someone help me out here?
A possible solution to this would be to check whether you can copy the cplex directory manually over towards the site-packages that are installed (you may need to use sudo).
From your stacktrace I see that you have installed cplex into
/Users/sb/Applications/IBM/ILOG/CPLEX_Studio1251/cplex/python/x86_darwin/
First run (I assume you python 2.7) in the interactive shell:
import site; site.getsitepackages()
See How do I find the location of my Python site-packages directory? for details about this step.
This will give you the directory of the site-packages where you need to copy the "cplex" directory to. I assume it is /Library/Python/2.7/site-packages from here
on a mac then run:
sudo cp -r ./cplex /Library/Python/2.7/site-packages/
This sets up the cplex manually as an importable package for your python installation. You should therefore be able to import cplex within the python interactive shell.
I am using an anaconda's python 2.7 distribution as my default python distribution. I receive a
Fatal Python error: PyThreadState_Get: no current thread
This error seems to be a result of a python distribution conflict; I am using anconda's python distribution but Leap motion's sdk anticipates the default mac distribution.
I followed Leap motion's sdk instructions on changing the default python distribution as follows,
install_name_tool -change /Library/Frameworks/Python.framework/Versions/2.7/Python
//anaconda/bin/python LeapPython.so
But now I receive the following error, which I have not been able to make much of,

I think the problem is that you are trying to load the Python executable, not the shared library. Since Anaconda doesn't seem to give you a framework, try replacing /anaconda/bin/python in your command with /anaconda/pkgs/python-2.7.10.0 or if that doesn't work, specify the full path to the Python dylib /anaconda/pkgs/python-2.7.10.0/lib/libpython2.7.dylib.
I installed ATpy-0.9.7 on my pc successfully and I also have the Python version of "2.7.5".
But when I import atpy I get the following error message:
>>> import atpy

I also installed db_sqlite3.egg-info. I don't know why this error message occurs!
I installed again th python2.7.5 with the following command :
./configure --prefix=$PYTHONPATH
but I also get this error after executing make:
Python build finished, but the necessary bits to build these modules were not found:
_bsddb _sqlite3 bsddb185
dbm dl gdbm
imageop sunaudiodev
To find the necessary bits, look in setup.py in detect_modules() for the module's name.
How could I run configure in order to install required C libraries?
If you are using a self built version of Python you need to ensure that both the base and the development sqllite3 packages are installed on your system before building Python.
If they are not and, as you said, you do not have superuser privileges, you can download and build sqlite locally, and get your Python build to use that version. This blog post describes how.
According to this question
How can I install sqlite3 to Python?
...you shouldn't have to install anything to get sqlite3 for python. Before I could import atpy I did have to install astropy (which was quite involved). After I did that, everything worked.
I am trying to make an executable with python, py2exe using Enthought. The program.py starts with:
import pandas as pd
import pyper as pr
r=pr.R(use_pandas=True)
The setup.py is as below:
from distutils.core import setup
import py2exe
import matplotlib
import sys
opts={"py2exe":{"bundle_files"}}
sys.argv.append('py2exe')
opts = {'py2exe': {"bundle_files" : 3, "includes" : [ "matplotlib.backends", "matplotlib.backends.backend_qt4agg", "pylab","numpy", "matplotlib.backends.backend_tkagg"], 'excludes':['_gtkagg', '_tkagg', '_agg2', '_cairo', '_cocoaagg', '_fltkagg', '_gtk', '_gtkcairo'], 'dll_excludes': ['libgdk-win32-2.0-0.dll', 'libgobject-2.0-0.dll']}}
setup(console=['program.py'],zipfile=None,options=opts,data_files=matplotlib.get_py2exe_datafiles())
After running:python setup.py py2exe the two folders dist and build were created. But when launched program.exe I got this:

I'm using Canopy 1.1.0 with Pandas 0.12.0-2 on a 64-Windows 7
Thanks for any help.
It looks as though the .exe built by py2exe may be missing the Intel MKL DLLs that come with Canopy (EPD). Depending on which version of Canopy (EPD) you have, the NumPy DLLs may be linked against the Intel MKL DLLs. Those DLLs should be in C:\Python27\Scripts directory (or the corresponding Scripts directory if you've installed EPD in a different place) -- look for DLLs whose filename starts with mk2.
EDIT: The path above works only for older EPD versions. For a more recent version of Canopy, the DLLS are typically located somewhere like C:\Users\<user>\AppData\Local\Enthought\Canopy\App\appdata\canopy-1.1.0-1371-win-x86_64\Scripts
