[IronPython] n-dimensional array
Hello everyone, I'm developing an application for my research project. I'm using IronPython as a scripting engine to allow easy data manipulation like Matlab. I require a high performance n-dimensional array class. Does anyone know of any .net library which provides a powerful n-dimensional array? I would like to do slicing operations on the array like in NumPy. (A[:2, :5] etc.) And also things like ones(.) zeros(.). I tried to use NumPy with Ironclad but im having some issues and would prefer if I could have a .net/ Ironpython ndarray library. Can you please recommend me any such library?

Re: [IronPython] .NET attributes for methods
This looks very promising but I cannot make it work. I have changed
product.py in DevHawk's example to:
#from clrtypeold import ClrMetaclass
import clrtype
class Product(object):
#__metaclass__ = ClrMetaclass
__metaclass__ = clrtype.ClrClass
_clrnamespace = DevHawk.IronPython.ClrTypeSeries
#_clrproperties = {

#cost:float,
#quantity:int,
#}
def __init__(self, name, cost, quantity):
self.name = name
self.cost = cost
self.quantity = quantity
def calc_total(self):
return self.cost * self.quantity
@property
@clrtype.accepts()
@clrtype.returns(str)
def name(self):
return self._name
@name.setter
@clrtype.accepts(str)
@clrtype.returns()
def name(self, value):
self._name = value
When I run it I don't see any items in the listbox. When I check the
name, it is a property:
py a.root.listbox1.Items[0]
= Product object at 0x002B
py a.root.listbox1.Items[0].GetType().GetProperties()
= Array[PropertyInfo]((System.Reflection.RuntimePropertyInfo object at
0x002C [System.String name]))
Whe I used the old clrtype with _clrproperties = {'name': str, ...}, it
worked.

Why do you say that the decorator approach will not work with
Silverlight? Does @notifiy_property from
http://gui-at.blogspot.com/2009/11/inotifypropertychanged-in-ironpython.html
use any feature not available in Silverlight?
It does not (as far as I know because it is pure IronPython). But
@notify_property does not work with clrtypes:
class ViewModel(NotifyPropertyChangedBase):
__metaclass__ = clrtype.ClrMetaclass
_clrnamespace = Cenda.ViewModel
_clrproperties = {'size': str}
def __init__(self):
super(ViewModel, self).__init__()
# must be string to two-way binding work correctly
self.size = '10'
@notify_property
def size(self):
return self._size
@size.setter
def size(self, value):
self._size = value
print 'Size changed to %r' % self.size
When I run this code, the size is still clr property and Python getter
and setter are not run.
So basically I need to override/enhance clr getter and setter created
by clrtype._clrproperties.

What do you think would be the best approach to create notifiable

but it seems to me it won't be possible to do it similarly for

Hi everyone, In the old IronPython hosting API there used to be a simple pyEngine.Shutdown() command. And then for cleanup we used: pyEngine.Dispose() What is the equivalent in the new hosting API's?

Re: [IronPython] .NET attributes for methods
I can help you create a property. And I can help you get it to work with your
decorators (you can check if the name property exposes your @notify_property
wrapper methods or not, and presumably that works). Beyond that, you are on
your own :)
I would try calling the property methods to make sure they are accessible.
Something like this. If that works, I am not sure what Silverlight needs to
make databinding happy.
props = a.root.listbox1.Items[0].GetType().GetProperties()
prop = props[0]
prop.GetGetMethod.Invoke(a, None) # call using Reflection
About the SystemError: Application code cannot access
System.AppDomain.get_CurrentDomain() using Reflection. error when defining
interfaces, it could be worked around. We need to call
AppDomain.DefineDynamicAssembly, and IronPython itself does do this. So its
just a question of figuring out the right way to access an AppDomain instance.
Will look into it, but I doubt it will help you with data binding.

py props

0x002C [System.String name]))

System.Reflection.TargetInvocationException: Exception has been thrown by the
target of an invocation.

Just for clarification a is Silverlight Application instance
As for the interface error - this is a different strory. You may
remember I created WCF service in IronPython with just interface defined
in C#. To be able to move interface to IronPython, I need such interface
to work with Silverlight too because Silverlight is the cause why I am
building WCF services.

Re: [IronPython] .NET attributes for methods
Thanks to Shri and the new clrtype both issues are resolved. I will post
details soon on my blog.

Help with getting properties to work will hopefully resolve the
databinding as well ;-)
The property getter looks wrong but I have no idea what's wrong:
py props = a.root.listbox1.Items[0].GetType().GetProperties()
py props
= Array[PropertyInfo]((System.Reflection.RuntimePropertyInfo object at
0x002C [System.String name]))
py prop = props[0]
py prop.GetGetMethod()
= System.Reflection.RuntimeMethodInfo object at 0x002B
[System.String name()]
py prop.GetGetMethod().Invoke(a.root.listbox1.Items[0], None)
System.Reflection.TargetInvocationException: Exception has been thrown by the
target of an invocation.
at module in string, line 0
Just for clarification a is Silverlight Application instance
As for the interface error - this is a different strory. You may
remember I created WCF service in IronPython with just interface
defined in C#. To be able to move interface to IronPython, I need such
interface to work with Silverlight too because Silverlight is the
cause why I am building WCF services.

I can help you create a property. And I can help you get it to work
with your decorators (you can check if the name property exposes
your @notify_property wrapper methods or not, and presumably that
works). Beyond that, you are on your own :)
I would try calling the property methods to make sure they are
accessible. Something like this. If that works, I am not sure what
Silverlight needs to make databinding happy.
props = a.root.listbox1.Items[0].GetType().GetProperties()
prop = props[0]
prop.GetGetMethod.Invoke(a, None) # call using Reflection
About the SystemError: Application code cannot access
System.AppDomain.get_CurrentDomain() using Reflection. error when
defining interfaces, it could be worked around. We need to call
AppDomain.DefineDynamicAssembly, and IronPython itself does do this.
So its just a question of figuring out the right way to access an
AppDomain instance. Will look into it, but I doubt it will help you
with data binding.

*Subject:* Re: [IronPython] .NET attributes for methods
This looks very promising but I cannot make it work. I have changed
product.py in DevHawk's example to:
#from clrtypeold import ClrMetaclass
import clrtype
class Product(object):
#__metaclass__ = ClrMetaclass
__metaclass__ = clrtype.ClrClass
_clrnamespace = DevHawk.IronPython.ClrTypeSeries
#_clrproperties = {
#name:str,
#cost:float,
#quantity:int,
#}
def __init__(self, name, cost, quantity):
self.name = name
self.cost = cost
self.quantity = quantity
def calc_total(self):
return self.cost * self.quantity
@property
@clrtype.accepts()
@clrtype.returns(str)
def name(self):
return self._name
@name.setter
@clrtype.accepts(str)
@clrtype.returns()
def name(self, value):
self._name = value
When I run it I don't see any items in the listbox. When I check the
name, it is a property:
py a.root.listbox1.Items[0]
= Product object at 0x002B
py a.root.listbox1.Items[0].GetType().GetProperties()
= Array[PropertyInfo]((System.Reflection.RuntimePropertyInfo object at
0x002C [System.String name]))
Whe I used the old clrtype with _clrproperties = {'name': str, ...},
it worked.

Here is an updated version of clrtype.py that uses @property +
@clrtype.accepts/@clrtype.returns to indicate a CLR property, instead
of using _clrproperties. I think its more Pythonic in general, but
also you should be able to modify @notify_property to work with it.
Note that notify_property won't just work. You will have to change it
to propagate the func_name, arg_types, and return_type properties
from the old getter/setter function objects to the new getter/setter
function objects since these values are used by clrtype to generate
the CLR members. Something like this:
class notify_property(property):
def propagate_attributes(old_function, new_function):
new_function.func_name = old_function.func_name
new_function.arg_types = old_function.arg_types
new_function.return_type = old_function.return_type
def __init__(self, getter):
def newgetter(slf):
try:
return getter(slf)
except AttributeError:
return None
propagate_attributes(getter, newgetter)
super(notify_property, self).__init__(newgetter)
def setter(self, setter):
def newsetter(slf, newvalue):
oldvalue = self.fget(slf)
if oldvalue

Hi,
I need implematation this's code in ironpython

please help me :(
Luis,
OK, you're in the wrong place (on the wrong list). You need to use
the standard implementation of Python 2.4 from www.python.org.
Good luck. We can't help you here any more.
Here is the google code link for pytesser:
http://code.google.com/p/pytesser/
PyTesser
PyTesser is an Optical Character Recognition module for Python. It
takes as input an image or image file and outputs a string.
PyTesser uses the Tesseract OCR engine, converting images to an
accepted format and calling the Tesseract executable as an external
script. A Windows executable is provided along with the Python
scripts. The scripts should work in other operating systems as well.
Dependencies
PIL is required to work with images in memory. PyTesser has been
tested with Python 2.4 in Windows XP.
Usage Example
from pytesser import * image = Image.open('fnord.tif') # Open image
object using PIL print image_to_string(image) # Run tesseract.exe on
imagefnord print image_file_to_string('fnord.tif')fnord(more examples in
README)
