Hi All



I am trying to embedded python with C#



I need to execute commands like this



*print math.sin(90)*



I am writing my code in C# using wrapper classes.



I wrote my code like this



  public void  TestCommandFileExecution(string code)

        {





            IntPtr modulePtr = Runtime.PyImport_ImportModule("math");




            IntPtr appPtr = Runtime.PyEval_GetBuiltins();





            IntPtr srcCompilation = Runtime.Py_CompileString(code, "<stdin>",
Runtime.Py_single_input);





            IntPtr execution = ExtendedRuntime.PyEval_EvalCode(srcCompilation,
appPtr, IntPtr.Zero);

            Runtime.PyErr_Print();









        }

And I am sending a code like this



CommandFileExecution("print 'test!'"); // Working fine




CommandFileExecution("print math.sin(90)"); // Showing a error like this.



*Traceback <most recent call last>:*

* File?<stdin>?, line 1,in <module>*

*NameError: name ?math? is not defined*

* *




Please help me


Thank you

Message-ID: <CADMpGLtmuSGpWeCOiwocMPj8L8qcSD9yhP_FX3OX-GcLvrW=5A@mail.gmail.com>

I am running python 2.6 and would like to use python for .net.  I have
downloaded pythonnet-2.0-alpha2-136-py26.zip and then copied the clr.pdl to
my python DLLs directory upon trying to "import clr"  I get ImportError:
dynamic module does not define init function (initclr). Ultimately I want to
include some code to access .net packages in my application using py2exe.

Any help

thanks

Hi,
you should copy both the clr.pyd and Python.Runtime.dll to the path which
contents in sys.path
like your current work directory and so on.
Hope it will help

I had tried this and did so again, it makes no difference. My observation
indicates that Python.Runtime.dll is used when running from mono I may be
wrong there. import of clr returns error indicating initclr is missing, my
understanding is this should be in the module and is needed for c
extentions. I am running from windows not mono and don't see even how
Python.Runtime could be called the name implies a package so it might be
possible to import with __import__()  but that doesn't sound right to me.
 Regardless that doesn't make any difference I still get the same import
error.

Help!

I am running python 2.6 under windows and would like to access some .net
code. I have downloaded pythonnet-2.0-alpha2-136-py26.zip from
source-forge.
I can run the python.exe in \python2.6-UCS2 folder and from there import
clr, however I want to import and run from my existing python2.6
installation. I put the clr.pyd file in sitepackages and also in DLLs but
when I get the following:

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 clr
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: dynamic module does not define init function (initclr)
>>>

I also could use a bit more documentation, I went to Bryan Lloyd's blog and
see:
Refactored import syntax: now you can use un-prefixed namespace names (
"from System import *") instead of the old "magic CLR module" syntax ("from
CLR.System...). The old "CLR." syntax is still supported until 3.0, but now
officially deprecated. This was the main compatibility problem with code
targeted for IP.

I can't figure how to get here!

what is the difference between the -UCS2 and -UCS4 folders?

CPython is compiled with one of two unicode modes.  The symbols in the dynamic library are different based on that original configuration flag.  Basically that config flag on python makes versions of python that are binary incompatible with one another even though they are the same version.  Native python extensions that link against python, need to therefore be linked against one or the other.  You can't link against both simultaneously.

Since most CPython native extensions are either pre built for a linux distribution (under the control of a managed package system), or are built on the target system itself, this is not an issue.   They know which flags were used by the python on the system.  In windows land, which is primarily a binary distribution land in which there is no cohesive binary package system managing the dependencies, your only real choice for binary distributions is to build both and provide them both.

If you try to run a mismatched binary with python, it will error out at runtime saying it can't find symbols, or entry points.  This would potentially look much like the error you post.  Though I would expect to see a more specific error info.  But at its base level, it would have trouble finding the function it was looking for, due to the function being fundamentally different in the data type of the parameters.  The symbol it was looking for would not be found.

Though there could be a myriad of other reasons why its having trouble finding that symbol.

I tried using the clr.pyd from both python1.6-UCS2 and python2.6-UCS4
folders, same results.  I am running the current python windows build:
Python 2.6.6 (r266:84297, Aug 24 2010, 18:46:32) [MSC v.1500 32 bit
(Intel)] on win32

Has anyone built clr.pyd for this distribution. I am not that familiar with
latest ms Visual Studio etc. Looking at src/ in svn I see mostly .cs files,
I would really like to be able to
import clr
then clr.AddReferenct(somefile)
# instantiat python object from somefile
xx = somefile.someobject()
...etc...

I can do this using the python.exe found in the python2.6-UCS2 folder, but
I want to use my regular python that has numerous packages and where I
build a product with py2exe...

What are my options, must I use the python distributed with pythonDotNet,
and if so what are the repercussions when trying to use other packages. I
see that if I run the python .exe that it gets my installed .site
information and therefore has access to all my libraries. What has been
done to this python.exe and can I simply move it to my python26/ directory?

It feels very strange to override the python.exe in the standard
distribution, what about things built with py2exe will they still work?

Any enlightenment would be much appreciated.
