Subject: [Python.NET] Operator overloading for managed objects

Hi All,

I am sorry for repeating the question, but I would like to make sure I am
not overlooking something here. Is this a known limitation that the
operators overloaded in C# are not working from CPython? So far I had
written CPython wrappers for the .NET objects that provide proper operators
implementation which is then redirected to explicit C# calls. While this
provides 'native' CPython experience and gives additional control over the
API exposed to a script (to some extend), it results in extra work, which is
mostly a problem on the long term when both C# and Python equivalents have
to be maintained in parallel.

did anybody have experience with using overloaded operators for managed
> objects? I have a class that have e.g. the operator+ overloaded in C#, but
> that does not seem to be picked up from the Python side. I have tried to add

Hi,

I followed the instructions from oleskii to build Python.NET for .NET4.0.
Compilation wend fine but when I try to run python.exe I get the
following error:

Unhandled Exception: System.DllNotFoundException: Unable to load DLL 'python26':
 The specified module could not be found. (Exception from HRESULT: 0x8007007E)
   at Python.Runtime.Runtime.Py_Initialize()
   at Python.Runtime.Runtime.Initialize()
   at Python.Runtime.PythonEngine.Initialize()
   at Python.Runtime.PythonConsole.Main(String[] args)

I have installed Python in C:\Python26.
Does any one an idea?

Is it necessary to use the python.exe build by the project or is it
also possible to use the original python executable?
When I try to use the original python executable I get the following error:
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)] on

Hi Bart,

the python26.dll is installed to the c:\windows\system32\ folder regardless
of where your main Python installation goes to. I've seen similar problem
when I have copied the Python26 folder to a new machine and forgot to take
the python26.dll along. Check if you have the python26.dll in place and make
sure you use the newly built python.exe interpreter.

It is indeed recommended to use the python.exe compiled with PythonNET as it
does some additional initialization (see the implementation of the
Initialize() method in pythonengine.cs code).

Hi Oleskii,

Thanks for the quick response.

I searched on my system for the python26.dll and I found it in
C:\Windows\SysWOW64.
I copied it to c:\windows\system32\ and now I'm getting the following error:

Unhandled Exception: System.BadImageFormatException: An attempt was made to load
 a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
   at Python.Runtime.Runtime.Py_Initialize()
   at Python.Runtime.Runtime.Initialize()
   at Python.Runtime.PythonEngine.Initialize()
   at Python.Runtime.PythonConsole.Main(String[] args)

Anny idea?

I have installed python 2.6.6 (32-bit) on a 64-bit version of Windows 7.

The problem that we have with the .NET version of python.exe is that
it takes some time before it starts.
As we use python in our build environment, it significantly slows down
our build process.

Regards,
Bart

Hi Bart,

I am no way an expert on this question, but it seem that your PythonNET is
trying to load a different version of runtime than the one he was compiled
against. You need to make sure the same runtime is built and used for
python.exe. To make sure the 4.0 is used, you can create / edit the
python.exe.config file (located in the same folder from where you start the
newly compiled python.exe) with the following contents

<?xml version="1.0"?>
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>

This will make sure the 4.0 is loaded (search
on useLegacyV2RuntimeActivationPolicy for more info, normally 2.0 will be
loaded).

If the above does not help here are a few questions that may point further
direction:
- Have you compiled for 32 or 64 bits (there is an .il for 64 bits, but I
haven't tried it myself)?
- Which version of runtime (2.0, 3.0/3.5, 4.0; x32 or x64 bits) do you have
installed?
- Do you start on the same machine where your development environment is
started or in a separate environment?

Regarding the startup time, do you experience slow start of pythonNET
version one time or every time it is started? I can imagine it is slow the
first time (as it has to load CLR), but the consequent starts have to be
reasonably fast.

Hi Oleskii,

I was able to solve the issue.

I had to change the Platform target to x86 instead of Any CPU for
every project in the solution.

It seems that Any CPU will result in an executable that will run as
64-bit application on a 64-bit system and as 32-bit on a 32-bit
system.
As I have a 64-bit system and have the 32-bit version of python
installed it will not load the python dll.

By forcing a 32 - bit build the python executable was able to load the
python dll.

Thanks for your support,
Bart

Hi Bart,

thanks for sharing the results! Indeed, you have to make sure the complete
stack is compiled for the same platform. I hope this will help other people
as well!

Has anyone been able to get this working on Windows 7 as 64 bit ?all the way down??
I?m about to have this thrown on my plate I think?

Hi Bart,

thanks for sharing the results! Indeed, you have to make sure the complete stack is compiled for the same platform. I hope this will help other people as well!

Hi Oleskii,

I was able to solve the issue.

I had to change the Platform target to x86 instead of Any CPU for
every project in the solution.

It seems that Any CPU will result in an executable that will run as
64-bit application on a 64-bit system and as 32-bit on a 32-bit
system.
As I have a 64-bit system and have the 32-bit version of python
installed it will not load the python dll.

By forcing a 32 - bit build the python executable was able to load the
python dll.

Thanks for your support,
Bart

Subject: [Python.NET] Multiple Initialize, RunSimpleString,
	Shutdown calls result in AccessViolationException
Message-ID: <AANLkTimVjN3v_WyqOAxY9P3kVET_deUWZ4u5SF8TeCsV@mail.gmail.com>

Hi All,

I am seeing weird problems with embedding PythonNET/Python 2.6 in a C#,
using 4.0 runtime application built with VS2010 on Windows XP SP3.

Design outline
--------------------
For every script I execute the following sequence on a separate thread (does
not seem to matter the same or different one every time) to avoid blocking
GUI:

PythonEngine.Initialize();

<the following block executed several times with startup scripts and then
the actual user script>
IntPtr pythonLock = PythonEngine.AcquireLock();
PythonEngine.RunSimpleString(source);
PythonEngine.ReleaseLock(pythonLock);

PythonEngine.Shutdown();

I use the RunSimpleString() as the RunString() didn't work for me (always
returns NULL and does not execute the code, suggestions welcome!).

Problem description
-----------------------------
Running simple scripts like 'print "whatever"' goes well. I can run scripts
multiple (>10) times without any side-effects. Problems start when importing
certain modules (like ctypes, numpy), or accessing collections of .NET
objects returned by the .NET API. For example, the following scripts will
fail executing SECOND time. Whenever I call the script AGAIN I get
AccessViolationException or even ExecutionEngineException (with debugger
attached of course) in the Shutdown() call.

Example 1
---------------
import ctypes

Exampe 2
--------------
import clr
clr.AddReference("System.Drawing")
import System.Drawing
bmp = System.Drawing.Bitmap("c:\\image.bmp")

I should be doing something completely wrong, but I just cannot see it...

Please help!

Hi!

Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

Thanks

Hi Sharon,

What do you want to achieve with this? If you want to provide path for
loading your own modules you can change the sys.path value by e.g. running a
'initialization' script with

import sys
sys.path.insert(0, 'your/own/path')

You can build up the script above in C# by inserting the path you need and
then performing e.g. RunSimpleString(<script>) like

string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> +
"')");
IntPtr pythonLock = AcquireLock();
RunSimpleString(script);
ReleaseLock(pythonLock);

Does this help?

Subject: [Python.NET] Invoking IPython programmatically
Message-ID: <AANLkTimQcqbA+thN5zRuRYtDRJ_bNaw1REi06TOBLrL3@mail.gmail.com>

Hello everyone,

I am relatively new to Python.NET, and I think that it will serve me very
well for the application that I am developing.

I am taking an application that had previously been implemented using
Python/wxPython/matplotlib/numpy/scipy, and reimplementing it using .NET 4.
The main reason that I'm doing this is because the application used to be
used primarily by technical people comfortable to working in a Linux
environment, but I am interested in making it usable by the Windows crowd.

On the other hand, I don't want to give up the ability to script the
application with Python, and I don't want to give up using
matplotlib/numpy/scipy. This is what has led me to Python.NET.

Following the email trail, I have been able to get the Console test program
running using VS2010 targeting .NET 4. What I'm now interested in doing is
to get IPython to load automatically, so the user does not have to manually
import IPython then call the IPShell mainloop. I am using Python 2.6.6,
IPython 0.10.1, pyreadline 1.6.2 all on XP SP3 win32.

So I modified pythonconsole.py like this:

    [STAThread]
    public static int Main(string[] args) {
        string [] cmd = Environment.GetCommandLineArgs();
        PythonEngine.Initialize();

        PyObject ip = PythonEngine.ImportModule("IPython");    <<<<<< new

        int i = Runtime.Py_Main(cmd.Length, cmd);
        PythonEngine.Shutdown();

        return i;
    }

Unfortunately, ImportModule returns null.  Then, from the command line, if I
manually import IPython, I get this

----
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit (Intel)]
on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import IPython
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python26\lib\site-packages\IPython\__init__.py", line 58, in
<module>

    __import__(name,glob,loc,[])
  File "C:\Python26\lib\site-packages\IPython\Shell.py", line 37, in
<module>
    from IPython import ultraTB, ipapi
  File "C:\Python26\lib\site-packages\IPython\ultraTB.py", line 93, in
<module>
    from IPython import Debugger, PyColorize, ipapi
  File "C:\Python26\lib\site-packages\IPython\Debugger.py", line 34, in
<module>

    from IPython import PyColorize, ColorANSI, ipapi
ImportError: cannot import name PyColorize
----

On the other hand, if I leave out this ImportModule from pythonconsole.py,
and manually import IPython from the command line, it imports successfully,
and furthermore I can run the IPython mainloop.

Ultimately, what I really want to accomplish is to get my .NET 4 application
to present the user with an IPython shell that has a .NET "Application"
object injected into its namespace, so the user can start interacting with
the .NET objects from the application, but also be able to do matplotlib
type stuff too.

Does anyone have any thoughts as to why I'm having problems importing
IPython programmatically?

Thanks,
-Frank.

Hi all,

Through some dirty fixes, I was able to build Python.NET on Ubuntu. Can
anyone please review and merge my patch (attached) ?

Thanks,
Vikas

Changes:
1. Added namespace to src/runtime/pyansistring.cs
2. Some generalizations in src/monoclr/Makefile
3. I was getting error "Irrecoverable syntax error" with ilasm on
clrmodule.il . Fixed by following changes:
   3.1 Renamed src/runtime/clrmodule.il to src/runtime/clrmodule.pp.il .
   3.2 Modified ./Makefile to run cpp preprocessor on src/runtime/
clrmodule.pp.il and generate src/runtime/clrmodule.il

Hazzah!  It build and runs...  Now if I can just get the MonoDevelop
debugger to fire the python.exe, so that I can do some tracing.
Any suggestions????

Thanks, to all very much,

The requirement I have is the ability to work with the .net side of my application interactively with Python. I really like the various autocomplete features of ipython, which is why I decided to go that way.

I finally figured out how to invoke ipython programmatically, using one of the Python environment variables, PYTHONSTARTUP, I believe. I'm on vacation at the moment so I don't have all of the details handy, but when I get back I will post them. 

Barton, can you please elaborate on why you think I should stay far away from ipython? If there are significant issues, I would be very interested in learning about them.

Thanks,
Frank.

In a word - Bloat -
But you very well may have an interesting solution to the auto-complete
issue.

I've been considering what to do about that in Boa for a while now.

Hi!

Trying to do as you said:


            string script = "import sys\nsys.path.insert(0, '" + modulePath + "')";

            IntPtr pythonLock = PythonEngine.AcquireLock();
            PythonEngine.RunSimpleString(script);
            PythonEngine.ReleaseLock(pythonLock);

And then:

            IntPtr gs = PythonEngine.AcquireLock();
            pyportal = PythonEngine.ImportModule(moduleName);
            if (pyportal == null)
            {
                                ?
                            }
           ?

I got Null value from the ImportModule.

When setting the PYTHONPATH manually in the system variables with the ?modulePath? and opening the VS is works.

Any idea?

Thanks,

SAHRON

Subject: Re: [Python.NET] Setting PYTHONPATH from code

Hi Sharon,

What do you want to achieve with this? If you want to provide path for loading your own modules you can change the sys.path value by e.g. running a 'initialization' script with

import sys
sys.path.insert(0, 'your/own/path')

You can build up the script above in C# by inserting the path you need and then performing e.g. RunSimpleString(<script>) like

string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> + "')");
IntPtr pythonLock = AcquireLock();
RunSimpleString(script);
ReleaseLock(pythonLock);

Does this help?

Hi!

Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

Thanks

Hi Sharon,

I don't use Python.NET, but I use IronPython and this is a snippet
I use to add PYTHONPATH to the sys.path object:

I use system variables to do so (for various reasons) at the studio.

import sys
from System import Environment as sysEnv

PythonPath = sysEnv.GetEnvironmentVariable('PYTHONPATH')
sys.path.extend(PythonPath.split(';'))


Hope this helps.

Hi!

I need to run some python scripts at the same time where each one of them is in different location & their location is not in the machine environment variable.

So, I need to declare for each thread its PYTHONPATH internally...

Any idea?

This is the code I use all the time to append a dir to the system path and then load assemblies from that dir. (note, they?re not in the GAC {woot!})

if os.path.isfile(myFile):
    if not myDir in sys.path:
        sys.path.insert(0, myDir)
    clr.AddReference("myAssembly")

myFile is the name of the assembly dll ala: ?C:/testdir/myAssembly.dll?
myDir would be: ?C:/testdir?

I always make sure that the namespace in the compiled assembly is the same as the filename. This seems to make things run more smoothly.

Hi!

Trying to do as you said:


            string script = "import sys\nsys.path.insert(0, '" + modulePath + "')";

            IntPtr pythonLock = PythonEngine.AcquireLock();
            PythonEngine.RunSimpleString(script);
            PythonEngine.ReleaseLock(pythonLock);

And then:

            IntPtr gs = PythonEngine.AcquireLock();
            pyportal = PythonEngine.ImportModule(moduleName);
            if (pyportal == null)
            {
                                ?
                            }
           ?

I got Null value from the ImportModule.

When setting the PYTHONPATH manually in the system variables with the ?modulePath? and opening the VS is works.

Any idea?

Thanks,

SAHRON

Hi Sharon,

What do you want to achieve with this? If you want to provide path for loading your own modules you can change the sys.path value by e.g. running a 'initialization' script with

import sys
sys.path.insert(0, 'your/own/path')

You can build up the script above in C# by inserting the path you need and then performing e.g. RunSimpleString(<script>) like

string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> + "')");
IntPtr pythonLock = AcquireLock();
RunSimpleString(script);
ReleaseLock(pythonLock);

Does this help?

Hi!

Can someone tell me how to set PYTHONPATH variable in code when working with Python.Runtime.dll without changing the value in the system variables before.

Thanks

Hi!

Did not understand the reply!

Do I need to change the PYTHONPATH from code?

Do I need to change the working directory in the C# program?

Why running the python script is not working?


Thanks,


SHARON

Hi!

Tried after your mail.

Does not change...

Regarding the PYTHONPATH:


I change it with code (System.Environment.SetEnvironmentVariable("PYTHONPATH",PathValue)) and it does not help me at the first run of the application. (I am getting Null value from the ImportModule)
But, after closing the application & opening it again it works (event if changing the PYTHONPATH in the code) with the PYTHONPATH that was set in the run before...

Any Idea?

Thanks,

SHARON

Hi!

Checked again and found that I had in the end of the module path string the char:"\".

After deleting it - it works for me as oleksii.bidiuk said:

string script = "import sys\nsys.path.insert(0, '" + <variable_with_path> + "')");
IntPtr pythonLock = AcquireLock();
RunSimpleString(script);
ReleaseLock(pythonLock);


( with the "\n" delimiter!)


Thanks to all!

Subject: [Python.NET] Pythonnet for Python2.7 binary distribution?
Message-ID: <AANLkTingVooi7Fjd+7E0PSRDqbQrSwPNHLnHYkcr8wMe@mail.gmail.com>

Hi Python.NET (is that the correct spelling..?) community!

I learned of Python.NET today. I love the idea of being able to use the .NET
assemblies/types directly from CPython. I've tried IronPython before, but it
just does not feel Python enough for me :)

But I failed to play with Python.NET tonight, since I'm at a CPython2.7
computer. I couldn't find a 2.7 port of Python.NET on SF, even though I
found a note about the changes necessary already being available:

http://sourceforge.net/tracker/?func=detail&aid=3094895&group_id=162464&atid=823894

/Olof

PS. I'd love to help somehow with this project, since my day-time work is
with a C# program, and I'm trying to integrate Python into "the loop" more
and more. DS
