QUESTION
I have a text parser written in Rust and want to provide a Python interface to it using pyo3.
The parser returns a HashMap within a HashMap and the values of the inner HashMap are of type serde_json::Value. When I try to return this as a PyObject I get an error that I am unable to solve.
This is a minimal exampel of my problem:
...ANSWER
Answered 2021-Dec-02 at 12:21The problem is that serde_json::Value doesn't implement the pyo3::conversion::ToPyObject trait. You can't implement that yourself either, since you can't implement a foreign trait on a foreign object.
What you can do is wrap your serde_json::Value and implement the trait on that. Something like this should work (untested):

I am trying to pass one Python object as an argument to a function that I am evaluating in the background with parfeval. The Python object is an instance of a Python class, and I detail it below. However, to reproduce the error, I will exemplify with a Python dictionary... However, simply using struct(pydict) would not work because I would lose all the attributes and methods in the Python class.
Assume the Python dictionary is
...ANSWER
Answered 2021-Nov-25 at 07:08One of the limitations of the MATLAB->Python support is that Python objects cannot be serialized. parfeval (and other parallel constructs) require serialization to transfer data from one MATLAB process to another.
You might be able to work around this by having each worker build the data structure directly and storing it / accessing it via parallel.pool.Constant, like this:
QUESTION
I am on WSL2 in VS Code. Using Zsh on VS Code.
I am trying to install pythonnet though am getting two errors: ERROR: Failed building wheel for pythonnet error: option --single-version-externally-managed not recognized
This is from using pip install pythonnet==2.5.2
My versions are: Python 3.8.10 Wheel 0.37.0 Mono: 6.8.0.105 pycparser 2.20
I have searched high and low online though I can't find a solution - everything seems to point to updating wheel and installing mono - as you can see from the above version numbers, I have them installed. I am doing everything from within a virtual env.
Does anyone have any experience with this or know what to do to get past these errors?

QUESTION
I am trying to write a function in rust that I can call from python that accepts a list of dictionaries (think pandas dataframe-like data) and access those key, values from rust. How can I accomplish this? I am using pyo3. Do I need to define a struct that matches the key, value pairs of the python dict input?
As a sample function, I am trying to pass in a list of dictionaries and sum the values corresponding to the key key into a total. Each dictionary in my python list of dicts has the key key which corresponds to an int.

QUESTION
I have some code that is using PyDict internally to store data. A user sets the data like you would with a normal python dictionary, and the data is stored by the C code in the PyDict object. My question is this: Do I need to reference count (Py_INCREF) the value AND the key? Just the value? The documentation indicates that calling PyDict_SetItem does NOT steal a reference for the value. My understanding is that this means the PyDict object is not responsible for the value PyObject, so the reference count needs to be incremented. No mention is made of the key in the docs - does it need to be incremented as well?
A related question involves the deallocator for my code - these reference counts need to be cleaned up - is there any "short cut" to iterate on iterables in the C API and decrement all references, or will I need to manually iterate on the PyDict object and decrement all the values individually (and possibly the keys, depending on the response to the above?)
The code in question would look something like this (with questions in the comments):
...ANSWER
Answered 2020-Dec-23 at 01:02You do not need to perform any reference count handling here. The dict owns all references it holds, and it will manage the incref/decref calls. You do not own any of the references being created or destroyed. You also do not need to call PyDict_GetItem.
The same goes for your deallocator. You only own the reference to the dict itself, not the dict's references to its contents. You only need to decref the dict. The dict will handle its contents.

Answered 2020-Sep-27 at 15:56The Pydiction plugin has not been maintained since 2014. YouCompleteMe, when configured correctly, should be able to do everything that Pydiction is able to do, and is still getting regular commits. You might consider just not using Pydiction.
Additionally, it's not usually a good idea to copy someones .vimrc wholesale, simply for reasons like this. Not saying that you can't, but if you do, you should take the time to read through the help documentation to make sure you understand what everything does.
However, if you really want to use Pydiction, a solution follows:
Solution:The plugin vim-scripts/Pydiction doesn't set g:pydiction_location by default. Since you're using Vundle with the default location, the included complete-dict should be located at ~/.vim/bundle/Pydiction/complete-dict. You'll need to set g:pydiction_location:

Install pydict
You can use pydict like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
