从Python子进程运行可执行文件时出错
我正在尝试从Python3.5运行一个可执行文件(线性规划求解器CLP.exe)从Python子进程运行可执行文件时出错,python,eclipse,python-3.x,pydev,clp,Python,Eclipse,Python 3.x,Pydev,Clp,我正在尝试从Python3.5运行一个可执行文件(线性规划求解器CLP.exe) Import subprocess exeFile = " C:\\MyPath\\CLP.exe" arg1 = "C:\\Temp\\LpModel.mps" arg2 = "-max" arg3 = " -dualSimplex" arg4 = " -printi all" arg5 = "-solution t solutionFile.txt" subprocess.check_outp
Import subprocess
exeFile = " C:\\MyPath\\CLP.exe"
arg1 = "C:\\Temp\\LpModel.mps"
arg2 = "-max"
arg3 = " -dualSimplex"
arg4 = " -printi all"
arg5 = "-solution t solutionFile.txt"
subprocess.check_output([exeFile, arg1, arg2, arg3, arg4, arg5], stderr=subprocess.STDOUT, shell=False)
在Eclipse PyDev中运行python文件时,可以在Eclipse控制台中看到结果
但是,在“solutionFile.txt”文件中没有保存解决方案结果
在Eclipse控制台中,我得到:
b'Coin LP version 1.16, build Dec 25 2015
command line - C:\\MyPath\\clp.exe C:\\Temp\\LpModel.mps -max -dualSimplex -printi all -solution C:\\Temp\\solution.txt

Problem ClpDefau has 1 rows, 2 columns and 2 elements

Presolve 0 (-1) rows, 0 (-2) columns and 0 (-2) elements
Empty problem - 0 rows, 0 columns and 0 elements
Optimal - objective value 4
After Postsolve, objective 4, infeasibilities - dual 0 (0), primal 0 (0)
Optimal objective 4 - 0 iterations time 0.002, Presolve 0.00
当我从命令行在MS windows shell中运行命令时:
C:\\MyPath\\clp.exe C:\\Temp\\LpModel.mps -max -dualSimplex -printi all -solution C:\\Temp\\solution.txt
我可以在解决方案文件中获得结果。而且,如果在命令行中运行该命令,粗体行不会显示在输出中
如果从Python子流程运行命令,为什么没有创建solition.txt文件,也没有保存任何解决方案结果 每个空格分隔的标记都需要是
子流程数组中的另一个参数。请检查\u输出
exeFile = " C:\\MyPath\\CLP.exe"
subprocess.check_output([
exeFile,

"-max",
"-dualSimplex",
"-printi",
"all",
"-solution",
"t",
"solutionFile.txt"],
stderr=subprocess.STDOUT,
