我正在Jupyter Notebook 中执行以下代码
import os
import shlex
files = os.listdir("./data/")
for file in files:
%run -timeout=5 -i solver.py ./data/$file
我得到以下错误：

显然，超时选项不起作用。
为我的代码设置超时选项的正确方法是什么？如果测试用例超过特定时间，例如5秒，我想停止执行
您可以进行
import os
import shlex
files = os.listdir("./data/")
for file in files:
! timeout 5 python solver.py ./data/$file
