Package installation and PyPi distribution

Trying to install this repository:

pip install git+https://github.com/xplip/pixel

Collecting git+https://github.com/xplip/pixel Cloning https://github.com/xplip/pixel to ./tmp/pip-req-build-ijxd55pn Running command git clone --quiet https://github.com/xplip/pixel /home/nlp/amit/tmp/pip-req-build-ijxd55pn Resolved https://github.com/xplip/pixel to commit efb38f5d54ee04874f61a92aebb3d8403fecf38c Running command git submodule update --init --recursive -q Preparing metadata (setup.py) … done

Then

python -c "import pixel"

Traceback (most recent call last): File “<string>”, line 1, in <module> ModuleNotFoundError: No module named ‘pixel’

I guess it does not install the actual python “package” called “pixel”.

If you would add PyPi distribution as well, it would not need to also install the git submodules, which actually takes long as datasets is big.

Here’s my suggestion: https://github.com/xplip/pixel/pull/3

However, the name pixel is taken, so you would need to come up with a different pypi package name (this does not change the fact that the installed package will be called pixel)

Sorry for the confusion, you can find the installation instructions by clicking on “Show instructions” under https://github.com/xplip/pixel#setup. Maybe I should make it easier to find. If you run this command conda install -c conda-forge pycairo pygobject manimpango instead of installing pycairo via pip, the error should hopefully be resolved.

Alternatively, running sudo apt install libgirepository1.0-dev gcc libcairo2-dev pkg-config python3-dev gir1.2-gtk-3.0 libpango1.0-dev libpangocairo-1.0-0 together with pip install pycairo PyGObject manimpango should do the job without conda.

Thanks for the suggestion! I think it’s a good idea to distribute pixel via PyPi. The main reason we currently only support the installation via eggs (running pip install -e git+https://github.com/xplip/pixel#egg=pixel should work) is because we rely on external system libraries (pango, cairo, pangocairo, and their respective dependencies) which need to be installed beforehand, and we give instructions on how to do so here in the repo. If we distributed the package as-is, people would be able to install it from PyPi without a warning and then encounter errors at runtime if they don’t have these external libraries installed. I think a good way around this will be to build some Linux and macOS platform wheels for pixel and distribute these via PyPi. I’ll try to do that this week 😃.
