解决只读系统拒绝的权限

Question

在Kaggle中使用python时，我正在尝试在os.system（command）函数中执行程序。该代码可直接在linux / unix命令行上运行，但不能在Kaggle中运行。简而言之，我遇到的错误是“只读文件系统”，后跟“ sh：权限被拒绝”。有谁知道如何解决这一问题？谢谢。

#!/bin/bash
import os, sys, stat
import os.path

os.chdir("/kaggle/input/llrdata")

TheCommand = 'chmod u+x ll64'
os.system(TheCommand)
TheCommand2 = './ll64 /kaggle/input/llrdata2/input.txt -d  -oThreadsPerTest=4'
os.system(TheCommand2)

输出：
