I installed the current pip package of mystic, which has version
>>> mystic.__version__
Out[9]: '0.2a1'
, the current stable version. However, many features from the examples are missing. Take for example this one, it uses
from mystic.solvers import BuckshotSolver
from mystic.pools import SerialPool as Pool
however my installation has neither solvers nor pools:
>>> from mystic import solvers
Traceback (most recent call last):
File "/usr/local/anaconda2/envs/myenv2/lib/python2.7/site-packages/IPython/core/interactiveshell.py", line 2885, in run_code
exec(code_obj, self.user_global_ns, self.user_ns)
File "<ipython-input-11-5babfa66b1af>", line 1, in <module>
from mystic import solvers
ImportError: cannot import name solvers
What am I missing? I tried installing both via pip, and via conda skeleton pypi, both to no avail.
I'm the author. The issue is that the latest stable release is old -- very old. It's several years stale. Don't use it. Ok, so that's embarrassing… but for whatever reason, I haven't released mystic in a couple years. Development has been very steady over the past few years, and there has been a lot of growth in the package -- just no release. So, obviously that needs to be corrected. It's just been one of those things that keeps getting put on next week's pile of things to do. So… you'll have to install from the git repository until I can get a new stable release together.
Something like this might work:
pip-2.7 install --target=test git+https://github.com/uqfoundation/mystic.git@master

The biggest issue is the version number is no longer supported as a valid format, so you need to install it as a "pre-release". See discussion here (for a related issue):

You should open a similar ticket for mystic.
UPDATE:
mystic now has a new release, so you can use pip as expected.
