[Chimera-users] scipy problem

[Eric Pettersen]

Yes, MMTK — which we use under the hood for minimization, computing MD trajectories, and a few other things — will not work with numpy 1.9 or newer.  This is obviously a problem for installing an up-to-date scipy.  You never really said what your overall goal was that required scipy, but maybe you could use PyChimera?   https://pychimera.readthedocs.io/en/latest/ <https://pychimera.readthedocs.io/en/latest/>

It’s in the Chimera Programming FAQ <https://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/faq.html>.  Question 3b.  If those instructions don’t work, please let us know.
