Hi All,
I am using Ironpython to call a python method from my C# class.
This is how i call the python method.
ScriptScope scope = runtime.CreateScope();
ops = engine.Operations;
ScriptSource source = engine.CreateScriptSourceFromFile("nlp.py");
source.Execute(scope);
object klass = scope.GetVariable("nlp");
object instance = ops.Invoke(klass);
method = ops.GetMember(instance, "identify_dtag");
object[] parameters = new object[1];
parameters[0] = line;
object output = ops.Invoke(method, parameters);
return output.ToString();
Error occurs atobject output = ops.Invoke(method, parameters); line.
In this python method, I am calling a method in the NLTK toolkit.
System configurations: Ironpython 2.7, python 2.6, C# 4.0
This is called in a threaded environment. However, currently only one thread is
active.
Hope someone can help me out.
Here is the stack trace:
System.InsufficientMemoryException: Exception of type 'System.InsufficientMemory
Exception' was thrown.
