Geomm fails with newer version of pymanopt

[murthyrudra]

Hi,
running geomm with the latest version of pymanopt gives the following error

Traceback (most recent call last):
  File "geomm.py", line 16, in <module>
    from pymanopt.manifolds import Stiefel, Product, PositiveDefinite, Euclidean
ImportError: cannot import name 'PositiveDefinite'

Rudra,
We will check and get back.

You can replace PositiveDefinite with SymmetricPositiveDefinite everywhere in the script.
I'm guessing the authors changed the API a bit in the new version.

Hi, It is not restricted to change in class names from PositiveDefinite with SymmetricPositiveDefinite . The signature of the class Problem is also changed.
Old constructor used in GeoMM
problem = Problem(manifold=manifold, cost=cost, arg=[U1,U2,B], verbosity=3)
New constructor in the pymanopt library
def __init__(self, manifold, cost, egrad=None, ehess=None, grad=None, hess=None, precon=None, verbosity=2):

[agoel00]

Yep, you are right!

pip install pymanopt==0.2.3
pip install scipy==0.18.1

This should work

Hi,
Is anyone able to solve the problem with the constructor of the class Problem?
