Hi! Can you run with python 3.8 and CVXPY 1.4 or higher? Python 3.7 is no longer supported by the Python Software Foundation, and we no longer support CVXPY 1.3 (following the recent release of 1.5).

Thank you for your reply. I will try using Python 3.8

[LP123MYM]

I tried Python=3.8.1 and cvxpy=1.5.1, but still reported the above error。I ran it for about two days and reported an error，Below is the minimum error example:

import numpy as np
import cvxpy as cp
temp_lr = 1.0/15/8.0
num_rep = 50
T = 10**6
s_t = 0
cum_loss_est = np.array([0.0, 1.0,2.0,3.0,4.0,5.0,6.0,7.0])
for run in range(num_rep):
    for t in range(T):
        w = cp.Variable(8, pos=True)
        obj = cp.Minimize(temp_lr * (cum_loss_est.T  @ w)  - cp.sum(cp.entr(w)) - (2*temp_lr) * cp.sum(cp.log(w)) )
        cons = [cp.sum(w)==1]
        prob = cp.Problem(obj,cons)
        prob.solve(solver='ECOS')
        s_t  += 1
        print("s_t ",s_t)
