问如何在使用cvxpy和CBC的python脚本中使用pyinstaller构建exe？

EN

import numpy as np
import cvxpy as cp

if __name__ == "__main__":

                  [1, 0, 2],

    b = np.array([4, 8, 6])
    c = np.array([3, 4, 2])

    # Define and solve the problem.
    x = cp.Variable(3)
    prob = cp.Problem(cp.Maximize(c.T @ x),
                      [A @ x <= b, x >= 0])
    prob.solve(solver=cp.CBC)
    print(f"solver: {prob.solver_stats.solver_name}")

    # Print result.
    print("The optimal value is", prob.value)
    print("A solution x is")
    print(x.value)
