Hi guys,
I have been reading a lot about web ide, which we can use to build algorithms and that there is no allowance to import third party modules or libraries. However for the purpose of test, I imported numpy and it seems it works. My question is, which libraries, can we use, is there any guidence? I would appreciate your reply. Thank you
The third party module limitation is driven by our security needs. Since we let anyone run arbitrary python on our servers, we have to disallow libraries that could be used to hack our platform - os for instance. Many libraries add references to things like os, so we are careful about what we allow access to.
If you have a library you are interested in, let us know so that we can review it.

Hi Dan, it would be useful if you allow users to import modules that are user-defined, but that do not use those potentially security-compromising libraries. For instance, it is possible traders composed their algorithms natively using a shell class:
class Equity(object):
...
@property
def net_income(self):
... This is useful because users can compose algorithms quickly using an interface they define, then plug in the Quantopian data API to implement such interface later. Having modules for these shell classes make notebooks code cleaner.
Hi Bao,
Thanks for the feedback. You're right that your workspace would be a lot cleaner if you could define your own modules and import them in Research and the IDE. This is actually a request that has been made by our own engineers as well and it's on our long-term roadmap. We don't have a timeline on when it will be done, but as someone who writes many examples in the community, I recognize the benefit that it will bring to the workflow on Q.
Thanks again for the suggestion. I'll mark this thread down internally so we can post an update here when we take on this project.
