Please see contribution-guide.org for steps we expect from contributors before submitting an issue or bug report. Be as concrete as possible, include relevant logs, package versions etc.
Please check the Gensim FAQ page before posting.
The proper place for open-ended questions is the gensim mailing list. Github is not the right place for research discussions or feature requests.
For developers: see our Developer Page for details on code style, testing and similar.
Thanks!
