Modify Code#
This version of OpenPifPaf (openpifpaf-vita) cannot co-exist with the original one (openpifpaf) in the same environment. If you have previously installed the package openpifpaf, remove it before installation to avoid conflicts.
For development of the openpifpaf source code itself, you need to clone this repository and install it:
git clone https://github.com/vita-epfl/openpifpaf
pip3 install --editable './openpifpaf[dev,train,test,backbones]'
The last command installs the Python package in the current directory (signified by the dot) with the optional dependencies needed for training and testing. If you modify C code, run this last command again which recompiles the static code.
Develop your features in separate feature branches.
Create a pull request with your suggested changes. Make sure your code passes
pytest, pylint and pycodestyle checks:
pylint openpifpaf
pycodestyle openpifpaf
pytest
cd guide
python download_data.py
pytest --nbval-lax --current-env *.ipynb
Things to Contribute#
This is a research project and changing fast. Contributions can be in many areas:
Add a new dataset?
Add a new base network?
Try a different loss?
Try a better multi-task strategy?
Try a different head architecture?
Add a new task?
Run on new hardware (mobile phones, embedded devices, …)?
Improve training schedule/procedure?
Use it to build an app?
Improve documentation (!!)
…
Missing Dependencies#
OpenPifPaf has few core requirements so that you can run it efficiently on servers without graphical interface.
Sometimes, you just want to install all possible dependencies. Those are provided as “extra” requirements.
Use the following pip3 command to install all extras.
pip3 install "openpifpaf-vita[backbones,coreml,dev,onnx,test,train]"
Your Project and OpenPifPaf#
Let us know about your open source projects. We would like to feature them in our “related projects” section.
The simplest way to integrate with OpenPifPaf is to write a plugin. If some functionality is not possible through our plugin architecture, open an issue to discuss and if necessary send us a pull request that enables the missing feature you need.
If you do need to make a copy of OpenPifPaf, you must respect our license.
Build Guide#
pip install jupyter-book
cd guide
jb build .
If you encounter issues with the kernel spec in a notebook, open the notebook
with a text editor and find metadata.kernelspec.name and set it to python3.
Alternatively, you can patch your local package yourself. Open
venv/lib/python3.9/site-packages/jupyter_cache/executors/utils.py
in your editor and add kernel_name='python3' to the arguments of nbexecute()
here.
Alternatively, for continuous integration, the kernel_name is replace in the json of the
Jupyter Notebook before executing jupyter-book
here.
Only use this operation on a discardable copy as jq changes all formatting.
Build Environment#
Below are information about the system that built this guide and all examples in it. To debug an issue, it can be helpful to run these commands on your system and see what is different.
