Open Source: sustainability and etiquette
by Reshama Shaikh Oct. 11, 2021

Oct. 11, 2021

Hello, I've seen some excellent resources that have explained open source, its sustainability, challenges and *indirectly, the etiquette*. I am starting to compile the list here [a]. This keynote by Stuart Geiger is a must-watch: The Invisible Work of Maintaining & Sustaining Open Source Software [b] There is one more video by Emily someone who was at Microsoft, but is now a professor somewhere, and I am trying to track that video down. I think it's from 2017. I'll add it to the list once I find it. If anyone knows the full name of the speaker, please share.

Spanish translation proposal for Scikit-Learn documentation
by Mariangela Petrizzo Aug. 17, 2021

Aug. 17, 2021

Dear Scikit-Learn team! I am Mariángela Petrizzo, I am writing to you as a member of Qu4nt, a team dedicated to the use of open source tools for the development of software solutions with emphasis on data science. We have a strong interest in translating the Scikit-Learn documentation into Spanish. Our team is made up of members from various scientific fields, including some university faculty in linguistics and computer sciences, with a wide experience in Python as well as several libraries used for data analysis and machine learning, and also contribute locally as evangelists of its use in Spanish-speaking communities, in particular, the leader initiated the translation of some Software Carpentry lessons into Spanish. That is why we have been discussing the opportunity to offer our contribution to the Python project, promoting the translation into Spanish of the documentation of some of the libraries with the greatest impact in our areas of interest. Talking with David Mertz, to whom we are sending a copy of this email, we have explored options, and the idea of working with Scikit-learn has really seemed to be an exceptional opportunity for all of us and the community. He's very enthusiastic about the idea of generating a spanish translation of Scientific Python libraries like Scikit-learn. For us, this translation project has to be done through a completely open work on Github, taking as reference the restructured text sources for Sphinx from a git fork, using the tools provided by Sphinx itself for internationalization: https://www.sphinx-doc.org/en/1.8/intl.html, and applying tags to perform planned updates. In addition, as with any open source project, the main mechanism for quality assurance comes from the users themselves who will have the channels available for submitting issues. Our intention is to secure all the infrastructure and mechanisms to make this possible: making the process transparent through Github, using as much as possible tools like Transifex to facilitate participation, and providing guidelines for contributors as part of the project. Of course, this project cannot be realized without your support. We therefore come to you to inquire about your willingness to accompany and support this project. We would love to hear your feedback on our proposal.

Invitation to lead a virtual sprint at SciPy US 2021
by Juan Nunez-Iglesias April 29, 2021

April 29, 2021

Hi all, I myself have come around to Gaël's idea that mature projects like scikit-learn are not the best place for newcomers to contribute. However, since the scikit-learn team has run a lot of remote, beginner friendly sprints in the past, there are clearly exceptions! Additionally, I suspect many people on this list have smaller projects that would make for great sprint topics. So, I would like to invite scikit-learners to submit sprint ideas for SciPy US 2021 here: https://forms.gle/w59mWNcA6JP9YA9z7 The sprint dates are July 17-18, and the sprint times are 9am-5pm US Central time. Please feel free to contact me if you have any questions about this. I'm happy to offer guidance on running a remote sprint for those that have suitable projects but have never run their own sprints before. (Though probably Reshama and Andy are the real pros here! 😂) Thank you, Juan.

scikit problems
by betsey_gogo April 26, 2021

April 26, 2021

I am getting frustrated. I am unable to run any scikit learning code because of an OS error OSError: [WinError 193] %1 is not a valid Win32 application I have tried 64 bit and 32 bit Anaconda installations to no avail. I have searched for help on the web. Others have seen this issue but the solutions are at best unclear. I don't know if I have an incorrect path variable of something more serious. Would you help?

Efficient forward stepwise regression
by Matt Schoenbauer April 26, 2021

April 26, 2021

Hello sklearn developers, I'd like to implement a forward stepwise regression algorithm using the efficient procedure described in the first problem here <http://stat.rutgers.edu/home/hxiao/stat588_2011/hw1.pdf>. It does not seem that such a model exists anywhere in Python. Would it be useful for me to write this model up for sklearn? If you're interested, here's a high-level view of how I think it would work: - The model would have sklearn.linear_model.LinearRegression as its base class. - The additional model parameters would include - An array of the indices (or column names) of the features in X1 - The Q and R matrices - The additional methods would include - An add_features() method that adds a specified number of features to the model. Updates all model parameters - A fit() method that requires a specification of the number of parameters to fit and optional sample weight. It calls the add_features method once on a model with no features. I would do this for OLS first, but supposedly it could be adapted for regularized models as well. How does this sound? Thanks, Matt S.
