I'm trying to use PyUNO as a method to convert different document formats (doc, wordperfect, html, etc) to PDF from within my Django server. I'm having a heck of a time getting import uno to work. It seems to fail when doing import pyuno, with a message of ImportError: DLL Load Failed: The specified module could not be found.
The only way I can get this to work is to use the Python 2.6 that came with OpenOffice, but I really want to use my other 2.6 installation. The docs for PyUNO are all for Python 2.2, and reputed to be out-of-date.
I'm guessing that some (or all) of the following files need to be copied from the OpenOffice directory to my site-packages directory (or some subdirectory thereof):
pythonloader.py
pythonloader.uno.ull
pythonloader.uno.ini
pythonscript.py
pyuno.pyd
Has anyone had any success getting this to work?
This is on Windows.
For simply conversions, you needn't reinvent the wheel. Look at unoconv: http://dag.wieers.com/home-made/unoconv/
'Import uno' will automatically work IF the python interpreter was bundled with OpenOffice, or in some Linux systems where the packagers have done a lot of work for you already.
Alternative 1: For other Python installs on Win32 systems, you need to import three environment variables and add one item to your Pythonpath. The detailed tutorial is at http://user.services.openoffice.org/en/forum/viewtopic.php?f=45&t=36370&p=166783
The three environment variables you must get FROM your OO-installed-Python and add TO your other install of Python are:
(Using Python 2.6 and OO 3.1.2)
os.environ['URE_BOOTSTRAP'] = 'vnd.sun.star.pathname:c:\Program Files\OpenOffice.org 3\program\fundamental.ini'
os.environ['UNO_PATH'] = 'c:\Program Files\OpenOffice.org 3\program\'
os.environ['PATH'].append('c:\Program Files\OpenOffice.org 3\URE\bin;c:\Program Files\OpenOffice.org 3\Basis\program;')
The pythonpath item you must add TO your other install of Python is the location of the uno module:
sys.path.append('C:\Program Files\OpenOffice.org 3\Basis\program')
Now you can simply 'import uno'.
Pyuno is only compatible with a similar version of Python. Since OO 3.1 bundles Python 2.6.1, that pyuno is only compatible with another Python 2.6. Attempting to import uno into a different version of Python will cause a runtime error. But there's a way around that in Alternative 2.
Alternative 2: For other Python installs on WIN32 systems, you can ignore the Python-UNO bridge completely and use the Python-COM bridge instead. You must install one new module, and the API has a few differences, but you can use ANY version of Python, including Python3.
Install the pywin32module to get COM access: http://sourceforge.net/projects/pywin32/
Discussion on the API differences: http://user.services.openoffice.org/en/forum/viewtopic.php?f=45&t=36608&p=168179
I also need an answer to this. I'm using windows XP and have a system where I extract data from a SQL server DB and insert it into template excel files. I DON'T want to add macro's etc to the OpenOffice. but I want to use the service to produce these files.
However, the only way I seem to be able to import the uno modude is to use the python.exe from the openoffice directory. even then I can't associate this exec with the py files in my system for some reason, thus I have to put in full path names each and every time.
I know that in Linux, the Pyuno module is an addon and can be used in normal python, but in windows this doesn't seem to be the case. I have listed all the relevant path details from the python exec under openoffice and duplicated them in python 2.7, but pyuno still fails with unable to find DDL with no reference to what DDL.
I think the answer is "this is not possible." From other reading on the web, it appears that the stdlib used to compile/link the python executable from python.org is different from the stdlib used to compile/link the python.exe distributed with OpenOffice.org. I don't know why, and I'm still confused by the fact that both pythons give me the same startup messages. So I could be completely on the wrong track here.

I try to write a simple plugin with gimpfu in python and I tried following those instructions.
1.2. Installation
Gimp-python consists of a Python module written in C and some native python support modules. You can build pygimp with the commands:
./configure
make
make install
This will build and install gimpmodule and its supporting modules, and install the sample plugins in gimp's plugin directory.
Where do I have to execute those commands?
I tried adding my script to the plugins folder but it seems like there is no python module called gimpfu. I believe I have to enable or install it in some way, but I can't find a solutio to do it.
EDIT: It seems like gimpfu is availible in the gimpfy-console insode gimp. It just doesn't seem to be availible for my plugin scripts.
No need to install anything. In the Windows versions Python support is built-in, and the gimpfu import is available when your code is executed by Gimp.
If you don't see the plugin in the menu it is likely a syntax error that doesn't let it run its registration code. See here for some debugging techniques.
However, since you mention PyCharm, you may have another Python interpreter installed and this makes things complicated because there can be conflicts depending on order of installation (and remember, Gimp uses Python 2.7)
Now it all depends if you are really doing a plugin (called from the Gimp menu) or a batch (where Gimp is called from a shell script), which is somewhat different. If you are writing a batch, see this answer for an example.
you don't need to install anything, on windows gimp comes with a python interpreter along with the libraries inside of it.
if you want to run your script from inside GIMP then you should check this answer and you should add the path to gimp to your system PATH environment variable (which is C:\Program Files\GIMP 2\bin on my system) , and instead of calling gimp-console.exe you should replace that with whatever gimp-console is currently available in that folder, the one on my system is gimp-console-2.10.exe.
I'm new to using python modules.
I'm currently working on a python 2.7 script that will be deployed to many remote computers (which have python 2.7 on them). The problem is that the script needs to use a module, which I am not allowed to install on those computers.
I'm wondering if it is possible to include the module files in the same package as my script (possibly have them compiled first), and then have the script import the library from that local folder, thus achieving a "portable" script.
If that is possible, how would I go about doing that?
Specifics: I'm running 2.7.11 on Windows needing to use Paramiko.
I'm asking this question because the similar questions that I can find either do not answer mine, or expect me to be familiar with core python structures with which I am not. I also DON'T want to include the entirety of python and then install the module onto that, something I see is often called Portable Python. I just want to send my script and the module and nothing more.
Many thanks!
To install modules in a specific directory, you can try pip install module --target=.
By default python search for those modules in same directory as the script first, then, if not available, it will search for python install lib files.
I've switched to Anaconda recently, but have encountered an issue. My python code uses a C++ shared library which receives raw frames from an interface. To do this, root permissions are generally required. So as not to use sudo for each execution, I generally give the python interpreter cap_net_raw and cap_ipc_lock capabilities (this is an academic setting, so no reason to worry about security, at least for now). Generally this works fine for the default python installation (I'm using Ubuntu 14.04.4), however when I try to do the same for the python executable of Anaconda (4.3.0, Python 3.6), I get the following error:
python: error while loading shared libraries: libpython3.6m.so.1.0:
cannot open shared object file: No such file or directory
The library is located where it should be, and ldd on the python executable shows that it's pointing to it. Adding it's path to LD_LIBRARY_PATH doesn't do anything. Remove the capabilities then restores this issue.
I tried this with a clean system install of Python 3.6, and there were no issues with it.
Would appreciate any input, thanks.
My question seems somewhat inane, but I cannot seem to find any resources for what I need to do.
Essentially I'm using my work computer to write python applications in my spare time. I'm using Python Portable (syntax version 3.2) because I do not have administrative access and can't do things with path variables etc.
How (if possible) do I install or import selenium so I can use it in Python Portable?
Thanks all!
Based on answer found Importing modules on portable python
and How to install external libraries with Portable Python?
Check for what import sys; print sys.path says?
It displays the list of directories and zipfiles where portable python looks for modules to import. Just copy your modules into one of those directories or zipfiles, or sys.path.append('/whatever/dir') if you have your modules in /whatever/dir and want to keep them there (the latter approach will last only for the current session, be it interactive or a script's execution).

You don’t have package I need, can I add it?
For simpler packages you can use easy install or even extract them in site-packages folder of
the Portable Python distribution. However some packages are installing additional dependencies
in windows system folders - in this case your Portable Python distribution will not work once
you move it to some other workstation. Make sure to do proper testing !
I've embedded python on a mobile device successfully, but now how do I include a python library such as urllib?
Additionally, how can I include my own python scripts without a PYTHONPATH?
(please note: python is not installed on this system)
The easiest way is to create a .zip file containing all the python code you need and add this to your process's PYTHONPATH environment variable (via setenv()) prior to initializing the embedded Python interpreter. Usage of .pyd libraries can be done similarly by adding them to the same directory as the .zip and including the directory in the PYTHONPATH as well.
Usage of the setenv() call can cause trouble on Windows if you're mixing c-runtime versions. I spent many aggrivating hours learing that setenv() only sets the environment variables for the version of the c-runtime your compiler ships with. So if, for example, Python was built with VC++ 2005 and your compiler is VC++ 2008, you'll need to use an alternative mechanism. Browsing the sources for py2exe and/or PyInstaller may provide you with a better solution (since you're doing essentially the same thing as these tools) but a simple alternative is to "cheat" by using PyRun_SimpleString() to set the module search path from within Python itself.
snprintf(buff, "import sys\nsys.path.append("%s")\n", py_zip_filename)
PyRun_SimpleString(buff)
