The issue about the cca caculate

[holyhao]

Thanks for your work, i meet some problems using the code.

CCA-images-text/main/cca.py

Line 54 in 977e22c

print 'Solving general eigenvalue problem'

The RH here need positive value, but it is caculated by the image and text features, which can not be guaranteed to be positive. Looking forward to your reply.
