os.system(run_GPU+'一个py文件'）这个run_gpu可以明显看出来是使用gpu，可这是什么用法

Question

import os, sys
import ConfigParser

#config file to read from
config = ConfigParser.RawConfigParser()
config.readfp(open(r'./configuration.txt'))
#===========================================
#name of the experiment!!
name_experiment = config.get('experiment name', 'name')
nohup = config.getboolean('testing settings', 'nohup') #std output on log file?

#create a folder for the results if not existing already
result_dir = name_experiment
print "\n1. Create directory for the results (if not already existing)"
if os.path.exists(result_dir):
pass
elif sys.platform=='win32':
os.system('md ' + result_dir)
else:
os.system('mkdir -p ' + result_dir)

finally run the prediction

if nohup:
print "\n2. Run the prediction with nohup (no GPU)"
os.system(' nohup python -u ./src/retinaNN_predict.py > ' +'./'+name_experiment+'/'+name_experiment+'_prediction.nohup')
else:
print "\n2. Run the prediction without nohup (no GPU)"

os.system(run_GPU +' python ./src/retinaNN_predict.py')

说明你有一个命令叫做run_gpu，具体看你的程序。
