pygsti cannot run on Windows about pygsti

[ldes89150]

After I installed psutil, I can use pygsti now. Is it possible to make psutil be one of its dependencies while installing with pip on Windows platform?

The resource module is usually included as part of the standard Python library (I think as of v2.7 at least?), so it's weird that your anaconda distribution doesn't include it. PyGSTi doesn't require psutil because it only uses it for memory profiling and can fall back on the (usually always-present) resource module if psutil isn't there. This is why your workaround works: if you have the optional psutil package then pyGSTi prefers this and resource is never needed. I think it makes sense to leave psutil as an optional dependency in pyGSTi, which leaves you with several possible workarounds:

• install a more complete Python for Windows; I've used Enthought Canopy successfully.
• install pygsti via pip install pygsti and install psutil separately, as you've mentioned.
• install pygsti with it's optional psutil dependency via pip install pygsti.[accurate memory profiling] (note: you can also use .[complete] which will cause pip to install all of pyGSTi's optional dependencies).

I'm closing this issue since the workaround is preferable to other long-term fixes.
