The constant array

__constant__ char max_string_sentinel[5]{"\xF7\xBF\xBF\xBF"};

is defined in a header file (device_operators.cuh). Therefore, when that header is included multiple times in multiple, separate compilation units, we will have compiling error saying that there are multiple definitions of max_string_sentinel.

https://igel.readthedocs.io/en/latest/_sources/readme.rst.txt includes a link to the assets/igel-help.gif, but that path is broken on readthedocs.

readme.rst is included as ../readme.rst in the sphinx build.
The gifs are in asses/igel-help.gif

The sphinx build needs to point to the asset directory, absolutely:

.. image:: /assets/igel-help.gif

Describe the bug
We should be able to compile the googletests of the libcuml++ algorithms without needing to compile the C wrappers (i.e. libcuml.so).

Steps/Code to reproduce bug
Configure the compilation of libcuml++.so and test/ml with:

cmake .. -DBUILD_CUML_TESTS=ON -DBUILD_CUML_CPP_LIBRARY=ON -DBUILD_CUML_C_LIBRARY=OFF

This leads to:

/usr/bin/ld:

Description

Currently our unit tests are disorganized and each test creates example StellarGraph graphs in different or similar ways with no sharing of this code.

This issue is to improve the unit tests by making functions to create example graphs available to all unit tests by, for example, making them pytest fixtures at the top level of the tests (see https://docs.pytest.org/en/latest/

I'm sorry if I missed this functionality, but CLI version hasn't it for sure (I saw the related code only in generate_code_examples.py). I guess it will be very useful to eliminate copy-paste phase, especially for large models.

Of course, piping is a solution, but not for development in Jupyter Notebook, for example.

Hi, Thanks for the awesome library!

So I am running a Kmeans on lots of different datasets, which all have roughly four shapes, so I initialize with those shapes and it works well, except for just a few times. There are a few datasets that look different enough that I end up with empty clusters and the algorithm just hangs ("Resumed because of empty cluster" again and again).

I conceptually
