Error when try to run example elliptical drag

[attaponaerospace]

I run via anaconda3 as pysph run elliptical_drop and got this error

Running example pysph.examples.elliptical_drop.

Information for example: pysph.examples.elliptical_drop
Evolution of a circular patch of incompressible fluid. (60 seconds)

See J. J. Monaghan "Simulating Free Surface Flows with SPH", JCP, 1994, 100, pp
399 - 406

An initially circular patch of fluid is subjected to a velocity profile that
causes it to deform into an ellipse. Incompressibility causes the initially
circular patch to deform into an ellipse such that the area is conserved. An
analytical solution for the locus of the patch is available (exact_solution)

This is a standard test for the formulations for the incompressible SPH
equations.
