Hi all,
I tried slsqp to solve an optimization problem.
Traceback (most recent call last):
File "test_slsqp.py", line 63, in <module>
x_opt=fmin_slsqp(func2,x0,bounds=bounds)
File
"/home/nwagner/local/lib64/python2.7/site-packages/scipy/optimize/slsqp.py",
line 184, in fmin_slsqp
full_output=full_output)
File
"/home/nwagner/local/lib64/python2.7/site-packages/scipy/optimize/slsqp.py",
line 309, in _minimize_slsqp
raise IndexError('SLSQP Error: If bounds is
specified, '
IndexError: SLSQP Error: If bounds is specified,
bounds.shape[1] == len(x0)
How should I define the box constraints for slsqp ? It
seems to be not unique for different optimizers in scipy.
