In the version of this article initially published online, the corresponding author designation was missing for Matt Haberland and Tyler Reddy. The affiliation for Evgeni Burovski was given as Higher School of Economics; the correct affiliation is National Research University, Higher School of Economics. In Box 1, “SciPy is an open-source package that builds on the strengths of Python and Numeric, providing a wide range of fast scientific and numeric functionality” was used as the box title; this has been moved to the beginning of the box text and a new title has been provided: “Excerpt from the SciPy 0.1 release announcement (typos corrected), posted 20 August 2001 on the Python-list mailing list.” From the original first sentence of this box, “(text following the % symbol indicates that a typo in the original text has been corrected in the version reproduced here)” has been deleted, and “% hanker to Hankel” and “% Netwon to Newton” have been deleted from the ends of the special functions row and the optimization row, respectively. In the first sentence of the ndimage section of Box 2, “nonlinear filter” has been changed to plural. At the end of the first paragraph of the section “SciPy matures,” “The library was expanded carefully, with the patience affordable in open-source projects and via best practices common in industry” has been changed to “The library was expanded carefully, with the patience affordable in open-source projects and via best practices, which are increasingly common in the scientific Python ecosystem and industry.” In Table 2, “Inequality constraint” has been changed to plural. In the “Nonlinear optimization: global minimization” section, “scipy.optimize.differentialevolution” had been changed to “scipy.optimize.differential_evolution.” In the first sentence of the section “Maintainers and contributors,” “SciPy developer guide” has been changed to “SciPy contributor guide” and the URL has been changed from http://scipy.github.io/devdocs/dev/core-dev/index. html to https://scipy.github.io/devdocs/dev/contributor/contributor_toc.html. In Table 2, entries in the first column have been changed from capitalized to lower-case. Finally, a URL in the second paragraph of the Discussion has been changed from https://scholar.google. com/scholar?q=SciPy to https://scholar.google.com/scholar?cites=2086009121748039507. The errors have been corrected in the print, HTML and PDF versions of the article.
