ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (4,) + inhomogeneous part.

Have u figure it out? Same error here.

Replace the following line of code
a = numpy.concatenate([[x.optimizer, x.objfname, x.executionTime, x.bestIndividual], x.convergence])
with this one solves the issue.
a = list([[x.optimizer, x.objfname, x.executionTime, x.bestIndividual], x.convergence])

The author[s] is requested to elaborate on the change in terms of potential issues.

Thx, problem solved~
