How to install extra-requires from a github link with `pip`

I have this python package located in a github repository. I can install it from the github link directly like so :
pip install git+https://github.com/mkdocs/mkdocs.git
I would like to do the same, but install some extra dependencies. When using just the package name, we can do :
pip install mkdocs[i18n]
But if I try :
pip install git+https://github.com/mkdocs/mkdocs.git[i18n]
It fails with the following error :
Looking in indexes: https://pypi.org/simple, https://pypi.ngc.nvidia.com
Collecting git+https://github.com/mkdocs/mkdocs.git[i18n]

How can I use extra-dependencies with github links ?

Following example 7 from https://pip.pypa.io/en/stable/cli/pip_install/#examples :
pip install "mkdocs[i18n] # git+https://github.com/mkdocs/mkdocs.git"
The '#' symbol usage is is explained in detail in PEP 440, in the section direct references.

This works:
pip install "git+https://github.com/mkdocs/mkdocs#egg=mkdocs[i18n]"
Added #egg=mkdocs.

How do I resolve error installing manim using poetry?

I want to setup manim community repo using poetry. I ran the command "poetry install". I am getting the following error.
Python 3.8.5, Pip 20.2.4

Use poetry only when you want to contribute to Manim Community itself, or else don't use it.
Now let's, come to the error. What the error, say's is it can't find some shared libraries. According to the docs, it says, you have to install Pango for it to work.
Possibly, you may have missed this step.

Cannot install python package due to cmake error

I am trying to install the disptools package by doing pip install disptools in my terminal.
The disptools package is linked here https://github.com/m-pilia/disptools.
It gives me a long error message during the installation with the main error displayed below.
Building wheel for disptools (setup.py) ... error
ERROR: Command errored out with exit status 1:

CMake Error:
Could NOT find OpenMP_C (missing: OpenMP_C_FLAGS OpenMP_C_LIB_NAMES)`
It also includes this in the error:

returned non-zero exit status 1.
I have looked everywhere online but I couldn't really find any helpful resources for solving this problem.
Would really appreciate it if someone can help.

With commands, python -m pip install disptools you try to download, compile and install the disptools.
Compilation step fails with a CMake error that tell that it failed to find library OpenMP. You can install it on a Ubuntu/Debian distribution with
sudo apt install libomp-dev
After this, you can launch again the pip command.
I hope you will meet all compilation requirements.

If you are using Anaconda Prompt (recommended),
conda install -c conda-forge dlib

how to fix "Command errored out with exit status 1"

I'm trying to install it on colab notebook.
The command I tried is :
pip install models
It's giving me error as:
Collecting models
Using cached https://files.pythonhosted.org/packages/92/3c/ac1ddde60c02b5a46993bd3c6f4c66a9dbc100059da8333178ce17a22db5/models-0.9.3.tar.gz
ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

Try:
pip install pymodels
This is documented here. This is because they renamed the module.
