@Rachel_hua Please read and carefully study my new CVXQUAD META post (you inspired me to include one particular sentence in the installation instructions 
). CVXQUAD: How to use CVXQUAD’s Pade Approximant instead of CVX’s unreliable Successive Approximation for GP mode, log, exp, entr, rel_entr, kl_div, log_det, det_rootn, exponential cone. CVXQUAD’s Quantum (Matrix) Entropy & Matrix Log related functions This may help you and others for future proiblems, and hopefully reduce my posting burdens, as I’d like to slide into semi-retirement as a question answerer on this forum.
