如何在ubuntu中运行这段C++代码？

5

我已经编译了这段代码：https://github.com/vbdaga/Rabbit-Cipher/blob/master/rabbit.cpp ，但g++ rabbit.cpp -o Rabbit没有任何关于如何传递参数的说明。我只看到getline哪些没有帮助...如果有帮助的话我使用 Ubuntu 22.04.2...有人知道如何继续吗？

为从串口收集的数据加上时间戳

5

我使用以下代码：https ://www.pythonpool.com/python-serial-read/ ，更具体地说是段落下的代码：Reading Data From Arduino Boards using Python Serial Read。我得到的数据是这样的：

123,344,555,661

124,345,674,611

1024,555,643,677

所以它在两行数据之间划了一条线。我用命令检查了它，python3 mycode.py > output.txt问题是一样的：两行数据之间有一个空行。我有两个问题：

如何删除空行？
如何将时间戳放在每行数据的前面？

/usr/bin/python：没有名为 pip 的模块

1

我正在关注本教程：https ://tensorflow-object-detection-api-tutorial.readthedocs.io/en/latest/install.html#tf-models-install ，更具体地说： 安装对象检测 API

当我运行这个命令时：

python -m pip install --use-feature=2020-resolver .

我得到：

/usr/bin/python: No module named pip

我尝试了以下组合：

UbuntuUser@ubuntu:~/Desktop/TensorFlow/models/research$ sudo python -m pip install --use-feature=2020-resolver .
/usr/bin/python: No module named pip
UbuntuUser@ubuntu:~/Desktop/TensorFlow/models/research$ sudo python3 -m pip install --use-feature=2020-resolver .

Usage:   
  /usr/bin/python3 -m pip install [options] <requirement specifier> [package-index-options] ...
  /usr/bin/python3 -m pip install [options] -r <requirements file> [package-index-options] ...
  /usr/bin/python3 -m pip install [options] [-e] <vcs project url> ...
  /usr/bin/python3 -m pip install [options] [-e] <local project path> ...
  /usr/bin/python3 -m pip install [options] <archive url/path> ...

no such option: --use-feature
UbuntuUser@ubuntu:~/Desktop/TensorFlow/models/research$ sudo python3 -m pip3 install --use-feature=2020-resolver .
/usr/bin/python3: No module named pip3
UbuntuUser@ubuntu:~/Desktop/TensorFlow/models/research$ sudo python -m pip3 install --use-feature=2020-resolver .
/usr/bin/python: No module named pip3

pip和pip3都安装在 Ubuntu Mate 中：

怎么了？？我在谷歌上试过：/usr/bin/python: No module named pip ，安装 pip 后它没有帮助......

我正在尝试安装 python-pygoocanvas 以运行旧的 ns-3 项目。如何在 Ubuntu 20.04.3 LTS 上安装它？我读过这个：无法找到包 python-pygoocanvas我不能说它对我有帮助:-(有更好的安装方法吗？

运行 chkrootkit 显示可疑文件和目录

-1

我进行了测试，看看我是否被黑客入侵。我得到了这样的回应：

Searching for suspicious files and dirs, it may take a while... The following suspicious files and directories were found:  
/usr/lib/jvm/.java-1.11.0-openjdk-amd64.jinfo /usr/lib/jvm/.java-1.8.0-openjdk-amd64.jinfo /usr/lib/python3/dist-packages/matplotlib/tests/baseline_images/.keep /usr/lib/python3/dist-packages/PyQt5/uic/widget-plugins/.noinit /usr/lib/debug/.build-id /usr/lib/modules/5.4.0-65-generic/vdso/.build-id /usr/lib/modules/5.4.0-64-generic/vdso/.build-id /usr/lib/nvidia-visual-profiler/.eclipseproduct
/usr/lib/debug/.build-id /usr/lib/modules/5.4.0-65-generic/vdso/.build-id /usr/lib/modules/5.4.0-64-generic/vdso/.build-id

所有这些信息都有问题吗？然而，运行“谁”和“最后一个”命令并没有显示一些不正常的东西。

无法在 Jetson nano 上安装 keras

我在运行 Ubuntu 的 Nvidia Jetson nano 上运行这个命令：

sudo pip3 install keras

我得到这个错误：

The directory '/home/jetson/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

如何安装 python-pygoocanvas，因为我需要它来运行旧的 ns-3.24 项目

运行 chkrootkit 显示可疑文件和目录

无法在 Jetson nano 上安装 keras

如何运行 .sh 脚本？

如何安装 .tar.gz（或 .tar.bz2）文件？

如何列出所有已安装的软件包

无法锁定管理目录 (/var/lib/dpkg/) 是另一个进程在使用它吗？
