我正在运行以下 JModelica 脚本:
#!/usr/local/jmodelica/bin/jm_python.sh
import pyjmi
op = pyjmi.transfer_optimization_problem("BatchReactor", "model.mop")
opt_opts = op.optimize_options()
opt_opts['n_e'] = 40 # Number of elements
opt_opts['IPOPT_options']['tol'] = 1e-10
opt_opts['IPOPT_options']['print_level'] = 0
res = op.optimize(options=opt_opts)
我原以为将 print_level 设置为 0 意味着 JModelica 和 IPOPT 会保持安静。这绝对有帮助!但我不断得到这样的输出:
time spent in eval_f: 0.00135 s. (26 calls, 0.0519231 ms. average)
time spent in eval_grad_f: 0.001719 s. (27 calls, 0.0636667 ms. average)
time spent in eval_g: 0.001636 s. (26 calls, 0.0629231 ms. average)
time spent in eval_jac_g: 0.002491 s. (28 calls, 0.0889643 ms. average)
time spent in eval_h: 0.003868 s. (26 calls, 0.148769 ms. average)
time spent in main loop: 0.055749 s.
time spent in callback function: 0 s.
time spent in callback preparation: 0.000459 s.
Total time: 0.46 seconds
Pre-processing time: 0.38 seconds
Solution time: 0.06 seconds
Post-processing time: 0.02 seconds
如何抑制这种输出？
最佳答案
您可以使用以下命令隐藏以 time gone 开头的行:
opt_opts['IPOPT_options']['print_time'] = False
