Hello! I have created a kedro matlab custom dataset which I would like to eventually contribute to the kedro datasets repo. May I ask how do I move forward?

Kedro-Datasets are a part of 
kedro-plugins
repo: https://github.com/kedro-org/kedro-plugins/tree/main/kedro-datasets
j
amazing @Samuel Lee SJ! as @marrrcin says, the way forward would be opening a pull request on 
kedro-plugins
, where 
kedro-datasets
lives ⭐
I had my fair share of MATLAB at university 😄

if you need any help making the contribution please shout! We’re more than happy to coach you through the process, what tests are required etc 🙂

As a former MathWorks and current Kedro software engineer, I am excited for this haha

I have used some scipy plugins. Would I need to pull the relevant functions into the repo? Or should I lift the functions from the scipy repo and place it in the kedro datasets repo? @Juan Luis
Hello @datajoely I am trying to install test requirements. It returns a command not found error. the code i used was pulled straight from the kedro-datasets repo under CONTRIBUTING.md
Copy code
make plugin=kedro-datasets install-test-requirements
j
that 
make
command looks good, can you paste the full error @Samuel Lee SJ? so we see what command is missing

Copy code
make : The term 'make' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the

Are you on windows? You may need to install make
j
yes, can you try 
conda install make -c conda-forge
@Samuel Lee SJ and repeat?

@Juan Luis I did and I managed to install make. Thank you.

@Juan Luis May I know the preferred python version for the kedro-datasets? This is because I have encountered an error regarding the install-test-requirements. I am running python 3.8.18 and my setuptools is currently version 59.6.0. When i run the make command, it returns with error ERROR: No matching distribution for setuptools >=61.2. Should I update my python version so that I can support a higher version of setuptools? Or should I install a higher version of setuptools manually?
<some context> I have run "pip install --upgrade setuptools>=61.2" and it returns with this error:

ERROR: No matching distribution found for setuptools>=61.2
Which is the same error as if I was running
Copy code
make plugin=kedro-datasets install-test-requirements
j
that's very weird, because there are versions well beyond 61.2 online 🤔 https://pypi.org/project/setuptools/68.2.2/ and they support Python 3.8 @Samuel Lee SJ do you mind doing 
pip install "setuptools==61.2" -vvv
and paste the (long) logs here?
and also the output of 
pip --version
s
@Juan Luis So the output of pip install "setuptools==61.2" -vvv is too long to create a snippet or even paste into the chat. I copied the last end of it

I think this is a known Windows error, in that 
pip
cannot upgrade itself because it's in use. first, I assume pip is installed with conda, so better to not meddle with that. can you do 
conda list
to verify that? and then do 
conda update pip
(also sorry this is taking so long 🙏🏼 I'm more than okay guiding you through the process, as long as you are patient enough to keep digging 😄)
and the other thing, maybe setuptools is installed through conda too. so if that's the case you can try 
conda update setuptools
s
(I am more than happy to sit and learn. I was about to say sorry for taking up your time)
🙏🏼 1
The conda install i think worked. But now conda is giving me problems. As you mentioned earlier, I think I am getting a similar error
Copy code
(kedro) PS G:\Working\kedro-plugins\kedro-plugins> make plugin=kedro-datasets install-test-requirements
cd kedro-datasets && pip install ".[test]"
Script file 'G:\miniconda3\envs\kedro\Scripts\pip-script.py' is not present.
make: *** [Makefile:67: install-test-requirements] Error 105
Does this mean that I cannot use a conda environment?
j
fair enough, at this point I suspect something got borked, because it's not normal that the 
pip-script.py
is missing. as annoying as it is, can you try 1. 
conda deactivate
2. delete the 
kedro
environment 3. create a new one (you can keep using Python 3.8 if you like, for now it's supported but will be dropped soon, maybe you can consider Python 3.9+) 4. activate and 
conda install make -c conda-forge
as we did initially 5. see if 
make ...
works

Does it matter which python version I create my matlab dataset on? Can I use python 3.10?
j
you can use 3.10 yes! it will be tested automatically in all supported Python versions
s
Nice.
@Juan Luis So I redid everything on python=3.10 I get a resolution error. Incompatibility between dask and kedro-datasets[test] This is the tailend of the code:
Copy code
ERROR: Cannot install dask[complete]==2021.12.0 and kedro-datasets[test]==1.8.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    kedro-datasets[test] 1.8.0 depends on dask~=2021.10; extra == "test"
    dask[complete] 2021.12.0 depends on dask 2021.12.0 (from <https://files.pythonhosted.org/packages/15/6d/99c63be3ea8a4a651d845addeea1f1b3bb8e5c6730bc26cfb6176631adf7/dask-2021.12.0-py3-none-any.whl> (from <https://pypi.org/simple/dask/>) (requires-python:>=3.7))

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

j
okay, we're making progress
it turns out you don't need all those test dependencies to develop @Samuel Lee SJ, this is a known issue https://github.com/kedro-org/kedro-plugins/issues/415 to run the tests, you can install only the pytest plugins and the ruff linter:
Copy code
pip install "pytest~=7.2" "pytest-cov~=3.0" "pytest-xdist[psutil]~=2.2.1" "pytest-mock>=1.7.1, <2.0" "ruff~=0.0.290"
and when running your tests, you can do 
pytest -k matlab
to only run the matlab-related tests, instead of everything

@Juan Luis I managed to sortof install pytest and while running
Copy code
pytest -k matlab
I get the following errors:

Then when I run pytest -k matlab in a directory higher pytest runs all the datasets. Could I get advice on how to proceed?
j
your first invokation is good @Samuel Lee SJ, but you haven't written any tests containing the word 
matlab
in the name yet. that's why it says "collected 0 items"
the coverage warnings are a consequence of that
the 
-k
flag looks for the test (function) names or module names, for example 
test_matlab.py
or 
def test_matlab_dataset
but if you already have the implementation, you can submit a pull request already and we can help you with the tests
