# Typing stubs for NVIDIA DeepStream Python Bindings
[](https://github.com/nkaaf/pyds-stubs/actions/workflows/audit.yml)
[](https://pypi.org/project/pyds-stubs)
This project provides type stubs for [pyds](https://github.com/NVIDIA-AI-IOT/deepstream_python_apps)
to improve the support of these important bindings in IDEs.
These are generated by [pybind11-stubgen](https://github.com/sizmailov/pybind11-stubgen) and further
post-processed. For the post-processing steps, check out
the [Post-Processing Chapter](#post-processing)
With the usage of this project, you agree to the license terms, found in the [License](#license)
chapter. This project is not affiliated with NVIDIA or the authors and maintainer of
the [pyds](https://github.com/NVIDIA-AI-IOT/deepstream_python_apps) repository. It is the result of
the need for type hints for a simpler and more stable implementation of DeepStream pipelines in
Python.

## Installation
This library can be easily installed with pip:
```bash
pip install pyds-stubs
```
## Usage
There is no magic, just only import pyds as you would normally do. This package is intended to be
used during the development and can be omitted in runtime environments.
## Versioning
The stub versions matches the versions of pyds. For example, stub version `1.1.8` fits to pyds
version
`1.1.8`. If any fix has to be applied, the fourth position would be incremented. So the first fix of
`1.1.8` results in `1.1.8.1`.
Please pin your version directly or limit it upper-wise like:
`pyds-stubs>=1.1.8,<1.1.9`
## Development
### Installation of Prerequisites
* Python 3 (latest) (https://www.python.org/downloads)
* Python venv (optional, recommended) <sub>[GoTo Installation](#python-venv)</sub>
* Installation of development requirements:
```bash
pip install -r requirements/dev/requirements.txt
```
* Installation of requirements:
```bash
pip install -r requirements/library/requirements.txt
```
### Build wheel
```bash
python3 -m build
```
### Generation
The stubs are generated by pybind11-stubgen. It is contained in the development requirements. The
stubs can be generated with the following command, if it is executed in the environment, where pyds
is installed.
```bash
pybind11-stubgen pyds
```
### Post-Processing
For correct usage, the generated stubs are post-processed. Following steps are applied:
* Format with ruff
* add generic class for `capsule` with information about the class of the object.
* remove class `GList` and add generic `GList` class with information about the class of the data.
* `cast` functions with `capsule` datatype: `capsule` is replaced by `capsule[class]` where `class`
is the target class.
* `array` datatype: Replace with numpy.ndarray
* `numpy.ndarray[float32]`: Replace with `NDArray[numpy.float32]` with
`from numpy.typing import NDArray`

### Notice for NVIDIA
I recently (Jun, 2025) saw
a [discussion](https://forums.developer.nvidia.com/t/feature-request-add-python-stubs-to-pyds-library/333191/4)
on your forum. If there is any official stub support by NVIDIA, this project will be deprecated and
publicly archived. I hope to hear from you ;)
