Subject: [Python.NET] Would you share your idea how to call python command
	from embedded Python.Net?
Message-ID: <CADtvxC9jcSjjb5dPiR8Mzu=RO999xyz-+OCF99E=usWgvGWm5Q@mail.gmail.com>

Hi,

I've been played with Python.Net for a week, but I can't find any sample to
use Python.Net in embedded way. I've searched many threads from the
previous emailing list, the result are not consistent, and looks like no
solution ??.

What I'm trying to do is that I want to get result (po) from C# code after
executing python command such as 'print 2+3' from python prompt.

When I executed it from nPython.exe, it prints out 5 as I expected.
However, when I run this code from embedded way. it returns 'null' always.
Would you give me some thoughts how I can get the execution result?

Basically, is this feature one of  Python.Net project intended for C#(.Net)
to be able to call python commands/scripts?

Thank you,
Spark.

using NUnit.Framework;
using Python.Runtime;

namespace CommonTest
{
    [TestFixture]
    public class PythonTests
    {
        public PythonTests()
        {

        }
        [Test]
        public void CommonPythonTests()
        {

            PythonEngine.Initialize();

            IntPtr gs = PythonEngine.AcquireLock();
            PyObject po = PythonEngine.RunString("print 2+3");
            PythonEngine.ReleaseLock(gs);

            PythonEngine.Shutdown();
        }
    }
}

Yes it is supposed to work.

But I'd point out that there is a big difference between the statements:

print 2+3

and

2+3

What exactly would you expect to get back as a return from the print statement?

Also wrote a simple console application using Python.Net,
But PythonEngine.RunString() returns 'null' so I got error.

namespace npythontest
{
    class Program
    {
        static void Main(string[] args)
        {
            PythonEngine.Initialize();

            IntPtr gs = PythonEngine.AcquireLock();
            PyObject po = PythonEngine.RunString("2+3");

            Trace.WriteLine("Python: " + po.ToString());

            PythonEngine.ReleaseLock(gs);

            PythonEngine.Shutdown();
        }
    }
}

Result is

Unhandled Exception: System.NullReferenceException: Object reference not
set toan instance of an object. at npythontest.Program.Main(String[] args)
in c:\temp\npythontest\npythontest
\Program.cs:line 20

I would expect above code will give some result. I think I'm stuck.

Message-ID: <CADtvxC8bNi7rtFmhr+cEgNwEG2ARVY3c+aD6cAEaO9HW+_u1YQ@mail.gmail.com>

Hi,

I ran every tests from src\tests. However, I can't run runtests.py and
test_module.py.

test_module.py has an error message in console window and pops up "Python
Console" with "Python Console has stopped working" message.  Would you tell
me what I need to check to run this script? It looks to me having a problem
when loading a module.

Thanks,
Spark.

Now I'm getting different error message after I have nPython.exe which I
compiled from source code.

According to the comments from test_module.py,

Line 209
               # This should fail until System.Windows.Forms has been
               # imported or that assembly has been explicitly loaded.
               # True for Windows; Not so for Mono 2.8.1

Line 214
               # The test fails when the project is compiled with MS VS
2005. Dunno why :(
# Fails (as expected) on Late Binding model. Works as expected on an
interactive sesson.

Is this failure as we expected in windows machine?

Thanks,
Spark.

Subject: [Python.NET] How to turn on console window from Windows System
 while debugging Embedded PythonNet app?
Message-ID: <CADtvxC9abf5ODKHNMXjhOEY2BB9+eOMxTkpjmeZHoUoEkS7ACw@mail.gmail.com>

Hi,

Actually, my questions are

            1. How to turn on console window(live) from Windows System
while debugging Embedded PythonNet app?
            2. How to capture python script execution output from C# code?

I've been talking to Brad at fie.us about my issue which I can't get the
output result of any python command using PythonEngine.RunString() or
PythonEngine.RunSimpleString().
I've been tried to debug simple code with Python.Runtime project, but can't
find how to turn on this console window, nor capture the python script
execution output.

What I'm trying to do is that I don't want to modify any python script when
running a python script from C# code, so I have below code:


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Python.Runtime;
using System.Diagnostics;

namespace npythontest
{
public class Program
{
static void Main(string[] args)
{
PyObject po;

PythonEngine.Initialize();

IntPtr pythonLock = PythonEngine.AcquireLock();
po = PythonEngine.RunString("execfile('c:\\cvs\\brocade.py')");
PythonEngine.ReleaseLock(pythonLock);

PythonEngine.Shutdown();
}
}
}

and a.py prints out many string output. I want to capture this output  by
RunString()/RunSimpleString() method, but it doesn't return any result
except 'null'. It seems it isn't for getting output.

Then, while talking to Brad, his screenshot from his Mac OS with Mono
displays the execution result output on an window like below, so wonder if
windows environment can have same console window.
Previously, Oleksii and Sharon mentioned in the thread
http://mail.python.org/pipermail/pythondotnet/2011-March/001103.html, but
don't know it's already implemented or not. However, I can't find how to
have same environment from my window system like Brad's Mac has.

So would you help me how to capture the python script output or have
console window for debugging when I'm using embedded PythonNet?

Thank you,
Spark.

What happens when you run a compiled application like mine, that has both c# and python console output, directly from within the windows command line cmd.exe?  Do you see the WriteLine() results from C# but not PythonNet?

That will tell you if it's an execution environment issue or an actual programming issue.  Which is still in question I think.

It's an escape character issue.

Since you are pasting source code in your source code, you need to double escape.  Probably as follows:

PythonEngine.RunSimpleString("execfile('c:\\\\temp\\\\a.py')");

the c# parser turns that into:  execfile('c:\\temp\\a.py')

And then python runs those escape characters and gets:  c:\temp\a.py

If you don't double escape, C# sends: execfile('c:\temp\a.py')

And therefore the escape characters \t and \a are executed, resulting in that weird value you got.

As you see the screenshot, I ran same application like you, but it doesn't
have any output which a.py's supposed to print 'aa' in the screen after
"Hello World!".

I retested with same code as you have and added online to execute a.py. It
looks it running but not the last line

        po = PythonEngine.RunString("execfile('c:\\temp\\a.py')");


[image: Inline image 2]



So I changed to

     PythonEngine.RunSimpleString("execfile('c:\\temp\\a.py')");

then, I got

[image: Inline image 3]

Hello World!
<module 'ntpath' from 'C:\Python27\Lib\ntpath.pyc'>
my\path
other\path
5
Traceback (most recent call last):
  File "<string>", line 1, in <module>
IOError: [Errno 2] No such file or directory: 'c:\temp\x07.py'

I don't know why it converted to 'c:\temp\x07.py' from 'c:\temp\a.py', and
got the error. Any idea?

WOW. Now I got it. Thank you much for the kind explanation. Now it works as
charm in Console Application in Windows system.
In the meantime, if it is not console window application, how I can
see/capture the text output? (I know it will work but want to capture the
output)

Any idea?

Hi Oleksii & Sharon,

If you've done this before, would you share which I can get a console
window in embedded Python.Net and get the Python string output from C#?

Thank you,
Spark.

Since all you are telling it to do is run a script and you are looking to capture it's output, I'd just use System.Diagnostics.Process to run "python.exe" with the args "c:\\temp\\a.py".  Then I'd use the returned Process object's Output stream object to read the lines from it's standard output and standard error.  No PythonNet required.  The other way to do it if you insist on using PythonNet to embed python rather than just spawn it as a subprocess, you can redirect use Console to redirect the streams for the running process yourself.  That should probably work as well.

Import clr causes windows service script to fail.
Windows Service script is for Pyramid:
https://github.com/Pylons/pyramid_cookbook/blob/master/deployment/windows.rst
Without WS script, "import clr" from python works.
Without "import clr", WS script works.
Together they fail. Setting "import clr" in script, the Windows Service 
will install but won't start. Setting "import clr" in any of the Pyramid 
views and the Pyramid application fails when the view is called.

That's usually x86 vs. x64 incompatibility - we need more info from you 
on this.
Sometimes it's simply a path configuration problem when the caller can't 
find the DLLs required.

That's usually the multi-byte character size symbol being set for 
Linux/Unix. For Windows you want UCS2 (two-byte characters)
Seems some of my Linux settings may have leaked onto the repo.

Since discovering that the post build event has not been needed since 
early .NET V2.0, I'm working on a unified build environment.
Hopefully the repo will be updated in sort order.
Thanks.

Barton,

You were right about the not finding the DLLs. I placed the clr.pyd and 
python.runtime.dll in the pywin32 egg directory and it seems to work 
now. Thanks!

Subject: [Python.NET] How to create an instance of C# from pythonnet?
Message-ID: <CADtvxC-hcYzBzL1qWP8TJFDaRoTwHUETykn1ojqcYp5eqp+_RQ@mail.gmail.com>

Hi,

I have Adapter.dll with namespace 'AAA.BBB.Adapter" written in C# which
gives network adapter information.
I want to call one of method GetSpeed(). I don't know How to create an
instance in python.
Would you give me some clue for writing the same python code like below
powershell script using python.net
I don't see any sample code which python creates C# class instance.


Python

I don't know how to create an instance of Adapter.


Thank you,
Spark.


Powershell

PS C:\CVS\PowershellITEExample> Import-Module .\LoadAdapter.psd1

What I use is:

import clr
from System.Reflection import Assembly
Assembly.LoadWithPartialName('Demo')
from Render import Demo

where the C# code has namespace Render and public class Demo.

Thank you for the reply.

I did

>>> import clr
>>> from System.Reflection import Assembly
>>> Assembly.LoadWithPartialName("Adapter")
<System.Reflection.RuntimeAssembly object at 0x05381148>
>>> from AAA.BBB import Adapter
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named AAA.BBB

I don't know why I got this. :-(
Any idea?

How about skip the import giving the error and call:
clr.AAA.BBB.Adapter()

I really don't know much about C#, or nested namespaces being called 
from python.net. You could try making a simpler C# dll and getting that 
to work and isolate the issue, which I think is the dot notated nested 
namespaces.

Try this from python with pythonNet installed (the current directory is 
assumed to contain Adapter.dll):

import clr
clr.AddReference("Adapter")        # Load the Adapter.dll
from AAA.BBB import Adapter    # Get the Adapter class type
adapter = Adapter()   # Create instance of the Adapter class
adapter.GetSpeed()    # Call the method

Thank you for the replies.

Now, I recompiled Python.Net with .Net 4.0 and get below working with
simple AAA.BBB.Adapter after reading

Now I have below sample code(Adapter.proj has two c# files), and
experimented

Class1.cs
-----------
namespace AAA.BBB.CCC
{

    public class Adapter
    {
        public string Function1()
        {
            return "AAA.BBB.CCC: Adapter Function1 Called";
        }
        public void Function2()
        {
            Console.WriteLine("AAA.BBB.CCC: Adapter Function2");
        }
    }

    public class Network
    {
        public string Function1()
        {
            return "AAA.BBB.CCC: Network Function1 called";
        }

        public void Function2()
        {
            Console.WriteLine("AAA.BBB.CCC: Network Function2");
        }
    }
}

namespace AAA.BBB
{
    public class Adapter
    {
        public string Function1()
        {
            return "AAA.BBB: Adapter Function1 Called";
        }
        public void Function2()
        {
            Console.WriteLine("AAA.BBB: Adapter Function2");
        }
    }

    public class Network
    {
        public string Function1()
        {
            return "AAA.BBB: Network Function1 called";
        }

        public void Function2()
        {
            Console.WriteLine("AAA.BBB: Network Function2");
        }
    }

}

Class2.cs
-----------
namespace AAA.CCC
{
    public class Adapter
    {
        public string Function1()
        {
            return "AAA.CCC: Adapter Function1 Called";
        }
        public void Function2()
        {
            Console.WriteLine("AAA.CCC: Adapter Function2");
        }
    }
}

Then, I got below. It seems working great.

C:\Automation\PythonNet>nPython.exe
Python 2.7.3 (default, Apr 10 2012, 23:31:26) [MSC v.1500 32 bit (Intel)]

>>> clr.AddReference("Adapter")

>>> adapter1 = Adapter()
Traceback (most recent call last):

NameError: name 'Adapter' is not defined
>>> from AAA.BBB.CCC import Adapter

>>> adapter1.Function2()

>>> network1 = Network()
>>> network1.Function1()

>>> from AAA.CCC import *
>>> adapter1.Function1()
u'AAA.BBB.CCC: Adapter Function1 Called'
>>> adapter1 = Adapter()
>>> adapter1.Function1()
u'AAA.CCC: Adapter Function1 Called'
>>>

My questions are

1. I don't know how to specify different namespace of class when creating
an instance.
2. The class that I already have has similar above layout in a project.
Common project has many class files in it, and each class has different
name space and class name.
AddReference('Common') looks working and loaded, but can't import.

>>> clr.AddReference('Common')
<System.Reflection.RuntimeAssembly object at 0x052E73C8>
>>> from Network import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named Network
>>> from Network.Common import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named Network.Common
>>>

Difference is that Common project has [Serializable] and enabled "Make
assembly COM-Visible"

    [Serializable]
    [Description("SimpleDictionary")]
    public class SimpleDictionary : ISimpleDictionary
    {
    ...
    }

Any thoughts?
Wonder if there is a way to list available class after AddReference().

Thanks,
Spark.

I think I resolved the issue which I need to import reference dlls prior to
import "from Network.Common import *".
Common uses many refereces from external *.dlls, once I imported all, then
I can import Common dll and use correctly.

Thank you for your helps.
Spark.

Subject: [Python.NET] Using embedded structs
Message-ID: <EBFABA77788633479F406E4E5E071065515656B8@XMB101BRU.rim.net>

Hi,

I am new at Paython and Python.NET and have been trying to use my own .NET assemblies.

I have been able to get going with mostly but cannot get passed using C# structs.

I have a class with an embedded struct

public class Log
  {
  public class PageManager
    {
          public struct Page
            {
                public long byteEnd;
                public long byteStart;
                public int indexEnd;
                public int indexStart;
                public long timestampTick;
                public DecodedItem firstItem;
                public DecodedItem lastItem;
            }
        }
}

In my C# code I just use Log.PageManager.Page but I cannot figure out how to create a Page object in Python.
(I need to pass a Page object as an argument to a method.)

Is this possible ?

Thanks
Morn? Joubert

Subject: [Python.NET] Importing .NET assembly with "." (dot) in the name
Message-ID: <22c2ac2d78082813352d84f7103c1175d58196e0@mail.qip.ru>

Hello,
Sorry for possibly dumb question, but is it possible to import an assembly with "." (dot) in the name ?
Without dot, for example "SlimDX.dll" - AddReference works and import works too.
But for "Accord.Imaging.dll" - AddReference is OK, but import fails:
>>> import Accord.Imaging
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named Accord

Is there a workaround for this or am I doing something wrong?
Any help appreciated.
Mikhail

import is namespace on the AddReference.

The import hooks look in the dll's that you've referenced, and search for
namespaces as per the argument to Accord.  So, you shouldn't import the dll
name.  If the assembly defines the namespace:

namespace AccordImaging
{
.......



Then, you should:

import AccordImaging

After you AddReference

Mark, thank you for your help.
Too bad that the original assembly which I am trying to use has namespace with "." in it:
namespace Accord.Imaging{
}

So in C#  "using Accord.Imaging'" works fine, but how to deal with it from Python?
Sure, I can write a "wrapper" application without dots in namespace, I tested it and it works.
But of course cleaner solution would be nice.

Subject: [Python.NET] Fwd: A question about pythonnet + pyinstaller

Hi All,

  So, the issue I'm running into is in combining pyinstaller with
pythonnet.  I'll describe my current situation.  Hopefully it isn't too
long and you have some insight.

  I have a little bit of UI put together via Windows forms.  I can run it
fine via pythonnet by doing "clr.AddReference('System.Windows.Forms')" to
load the assembly, doing "from System.Windows.Forms import Application" to
get at the Application class so I can do Application.Run(myform), and by
adding the location of my little UI dll to the python path and importing
classes I need from there.

  I can also happily do all this after building everything into an exe via
pyinstaller.  I did have to jump thru a few pyinstaller hoops to add my
little dll to the package pyinstaller builds as well as Python.Runtime.dll.
 The path to the location where those are added is appended to pythonpath
auto-magically by pyinstaller so they're found just fine.

  So then I found that I needed to get at System.ComponentModel.BindingList
and System.Drawing.Bitmap.  I thought all I'd have to do would be
"clr.AddReference('System')" and "clr.AddReference('System.Drawing')" and
then import BindingList from System.ComponentModel and Bitmap from
System.Drawing.  This worked fine when running from pure python but was
unhappy running from the pyinstaller-built exe.  In the exe it complains
that it can't import BindingList (or Bitmap if I comment out BindingList).
 I can make it work in the exe if I use a direct import instead of a 'from'
style import.  So if I do "import System.ComponentModel.BindingList"
instead of "from System.ComponentModel import BindingList" it works.
 However I don't think I should have to do a direct import and doing so
gives me problems in the pure python world.

  I actually don't even understand how the System.Windows.Forms assembly is
found in the exe scenario.  I don't add the System.Windows.Forms.dll to the
package that pyinstaller builds and yet it works just fine which implies
that it is being found elsewhere but I don't understand how (nor why it
doesn't find the other assemblies that I also want).

  Sorry for the long email.  Hopefully you have some insight.  Hopefully
you know what pyinstaller is so that the majority of this email makes some
sense =p

Thanks for any leads you can provide,
Jeremy

You are confused.  Mark was pointing out that since an assembly is not necessarily named on disk, the same as the namespaces within it, you need to AddReference the assembly on disk, and THEN import the namespace.  And the namespace may not be named the same as the reference.

PythonNet is perfectly capable of importing a nested dot delimited namespace.
