How to store PythonObject in DynamicVector?

I'm trying the following:
let module = Python.import_module("my_module")
let dv = DynamicVector[PythonObject]()
let result = my_module.my_func()
dv.push_back(result)
let module = Python.import_module("my_module")
let dv = DynamicVector[PythonObject]()
let result = my_module.my_func()
dv.push_back(result)
And getting:
cannot bind generic !mlirtype to memory-only type 'PythonObject'
cannot bind generic !mlirtype to memory-only type 'PythonObject'
I tried different combinations, but as long the type is non-imperative type, this won't work. What is a workaround for this?

"let" defines a variable that's immutable. "let dv = DynamicVectorPythonObject" Have you tried using "var"?

Yes. The problem isn't whether dv is immutable or not, it is that PythonObject is not "passable".

This is as far as I got 🙂
let obj = test_mod.return_int()
var dv = DynamicVector[Pointer[PythonObject]]()
dv.push_back(obj.py_object)
let obj = test_mod.return_int()
var dv = DynamicVector[Pointer[PythonObject]]()
dv.push_back(obj.py_object)
error: invalid call to 'push_back': method argument #0 cannot be converted from 'PyObjectPtr' to 'Pointer[PythonObject]

No idea where to get PyObjectPtr so it can be specified in DynamicVector parameter. Not sure if it even makes sense. Compiler errors are confusing in different scenarios. There's a lot of undocumented stuff.

This looks like a progress :mojo: I knew the answer would be in using pointers but didn't know how to put in code.
