Question

谁能帮我回答python这个问题？ 提示subprocess错误。

错误代码是这样的：
bogon:optimize YUEChao$ python optimization.py rs --max-iter 200
Run Random Search for 200 iterations
Traceback (most recent call last):
File "optimization.py", line 318, in <module>
args.func(args)
File "optimization.py", line 242, in run_rs
best = search_rs(search_space, max_iter, 'rs_')
File "optimization.py", line 22, in search_rs
cost = run_particles(pop,tmpdir+'/'+prefix)
File "/Users/YUEChao/Desktop/semic-master/optimize/tools.py", line 58, in run_particles
call(["mpiexec","-n","2","./"+exe,'"'+nml_prefix+'"',str(i0),str(i1)])

Answer 1

要贴源码啊，还必须带缩进的

Answer 2

No such file or directory
call的路径有问题
