以 nn 这次作业为例，若我将 nn.py 的内容改为

import time
time.sleep(2)

并运行 grade.py ，期望得到的报错信息是

Testcase data/in_1.hdf5: Time limit exceeded
Testcase data/in_2.hdf5: Time limit exceeded
...
Total Points: 0/100

实际得到的报错信息是

Testcase data/in_1.hdf5: No output file found
Testcase data/in_2.hdf5: No output file found
...
Total Points: 0/100

1. 试着看了网络配置，断网时 IP 地址还在
2. 断网时无法访问 auth4.tsinghua.edu.cn
3. 一般来说，五分钟之内会恢复

请问我应该排查其它什么地方？

我本地使用的系统是MacOS, 在本地测试和在git上测试唯一不同的是把所有的wc, cut命令换成了gwc, gcut，还有把sed -i换成了gsed
。在本地使用grade.sh顺利通过了测试，但在git上auto-grade时在task7failed了。
logs_16.zip
这是我在git上测试时的log。

git clone 时报错：
kex_exchange_identification: Connection closed by remote host
fatal: Could not read from remote repository.

网络连接正常，已经连接了sslvpn，之前提交和下载都正常。
.ssh/config 已修改过。

运行 ssh -vT [email protected] 显示：

连接数据库出现类似
Error : object 'xxx' is not exported by 'namespace:xxx'
的问题，我的解决方法是在R里执行
install.packages("tidyverse")

举个栗子：a文件同时依赖于b,c,d三个文件；程序在设计中决定了：b,c,d是被同一个脚本script.sh生成的。如果改动了bcd三个中的任何一个，我们希望改动能够传递给a，因此a的依赖必须写为
a : b c d
这时我们不希望重复运行script.sh，因此在b,c,d三者的依赖关系下的代码中，script.sh只能出现一次。这时应该如何书写b,c,d的依赖关系和对应的代码？

出错信息如下：

hz.h5 是一个正常的文件

vitables hz.h5                
Creating the Query results file...

Traceback (most recent call last):
  File "/usr/share/vitables/vitables/h5db/dbDoc.py", line 115, in openH5File

Please, if you think it is a bug, report it to developers.

File creation failed due to unknown reasons!
Please, have a look to the last error displayed in the logger. If you think it's a bug, please report it to developers.

出错信息如下：

1. 如果可以成功运行 apt install r-bioc-rhdf5 ，即可正常使用

2. 若依赖关系过于复杂，则可按以下方案手动安装：

rhdf5 的依赖较多，需从 R 内部安装。

在 Bioconductor 仓库中，需要使用 r-cran-biocmanager 来访问。

apt install r-cran-biocmanager

或者从 R 中安装

> install.packages("BiocManager")

然后在 R 的命令环境中执行

> require(BiocManager)
> BiocManager::install("rhdf5")

这将现场编译一个 rhdf5 的工具库，如果编译器不存在，可以安装

apt install build-essential

来解决

确认安装成功，可用

> require(rhdf5)

1、在终端中cd到grover-sunjy18
2、运行 python3 grade.py
3、报错

备注：
我的程序在别的同学计算机上运行没有出错
我自己重新克隆grover再重新拷贝代码运行依然报错
直接运行程序时存在有效输出
