我如何让JModelica变得安静？

Question

我运行以下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) 

我本来以为设置print_level到0将意味着JModelica和IPOPT会安静。它绝对有帮助！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 

我该如何抑制这种输出？

Answer 1

您可以通过抑制与time spent开头的行：

opt_opts['IPOPT_options']['print_time'] = False
