SciPy and NumPy project mailing lists¶
The mailing lists are our primary community forum. This is where we organize projects, announce new releases, plan future directions, and give and receive user support.
To post to a list, you have to be on it. If you want to see how much traffic a list gets, just go to the list archive and take a look. You can opt to receive messages in digest form. Groups of about 10 messages are sent in one email, with a table of contents at the top. This reduces inbox clutter, but means you will get the messages with a delay of up to a day.
Please only post job ads if the work involves not only using NumPy, SciPy, and
related packages but an opportunity to contribute to these packages as part of
the role (we love to see that become more common!). If that’s the case, please
[JOB] in the subject.
We also have read-only mailing lists setup for NumPy and SciPy that provide notifications of all version control checkins.
The following table lists the core NumPy and SciPy lists. Please see Before you post to make sure that this is the right place to ask your question.
Our user-support forum, for discussions of how to use SciPy.
For discussions about SciPy development (code, website, docs, and more).
For discussion of NumPy
StackOverflow is a good place to ask usage questions. Tag your question

Before you post¶
Search the appropriate archives first (one way is to use the “Read/Search” links to Nabble above). Though knowing what search terms to use is an acquired skill, it’s often easier than you think. Also check the Frequently Asked Questions to see if your question is answered there.
Please make sure that you’re posting to the right list. The NumPy and SciPy mailing lists should be used for questions relating to those two packages in particular (general questions about how to accomplish a scientific task in Python are okay, too). Questions about matplotlib should go to one of the matplotlib mailing lists. Questions specifically about using/developing the IPython shell should go to one of the IPython lists. Making sure your question is going to the right list saves everyone time and makes it far more likely the right people will see (and answer) your question quickly.
A few points on the mailing list etiquette:
Reply to list, not to sender.
In general, it is not necessary to CC respondents on further replies to your thread. Please reply to the list rather than to the list and the individual respondents (note that the NumPy and SciPy lists add Reply-To headers to facilitate this; normally, clicking ‘Reply’ in your mail client will direct replies to the list rather than the sender). Likewise, if you expect a reply, you should either monitor the list traffic through your mail client or through a service like Nabble; responses will generally be sent to the list and only the list.
Don’t reply to digests.
Digests should only be used if you intend to read and not participate. Replying to digests makes it impossible to follow conversation threads; please subscribe normally if you wish to participate in the conversation.
When replying to a message, please use bottom-posting. This means quoting the content you reply to and inserting your replies below each quote. For more details, see posting style.
Keep it friendly, folks.
Please keep the tone of conversations cordial and respectful, and recognize that those responding to your questions are volunteering their free time to do so. The SciPy code of conduct applies on SciPy lists and GitHub.
