Hi all,

Running the test with 0.5.0.1951 works fine

python -i test_ncg.py yields

Optimization terminated successfully.
         Current function value: 0.081014
         Iterations: 7
         Function evaluations: 8
         Gradient evaluations: 469
         Hessian evaluations: 0
fmin_ncg 8
Approximated smallest eigenvalue 0.081014052771

smallest eigenvalue by linalg.eigvals 0.081014052771
>>> import scipy
>>> scipy.__version__
'0.5.0.1951'

but hangs for '0.5.0.1954'

Any idea ?

Nils
