Bilal's questions

我正在使用 Ubunut 22.04，我想安装 nvidia 驱动程序：sudo ./cuda_12.1.0_530.30.02_linux.run，但我首先收到警告：

   warning: the compiler differs from the one used to build the kernel
     The kernel was built by: x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0
     You are using:           cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
   
   Warning: Compiler version check failed:
   
   The major and minor number of the compiler used to
   compile the kernel:
   
   x86_64-linux-gnu-gcc-12 (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0, GNU ld (GNU Binutils for Ubuntu) 2.38
   
   does not match the compiler used here:
   
   cc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0

我已经按照此解决方案将版本更改为 12.3，当我从终端检查时，我得到 gcc/g++ 版本 12.3。

最后我得到一个错误：cc: error: unrecognized command-line option '-ftrivial-auto-var-init=zero'，你能告诉我如何解决这个问题吗？提前致谢。

我尝试在 Jetson Nano 4G 上安装 CUDA 11

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/sbsa/cuda-ubuntu1804.pin
‍
sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600
‍
wget http://developer.download.nvidia.com/compute/cuda/11.0.2/local_installers/cuda-repo-ubuntu1804-11-0-local_11.0.2-450.51.05-1_arm64.deb
‍
sudo dpkg -i cuda-repo-ubuntu1804-11-0-local_11.0.2-450.51.05-1_arm64.deb
‍
sudo apt-key add /var/cuda-repo-ubuntu1804-11-0-local/7fa2af80.pub
sudo apt-get update
‍
sudo apt-get -y install cuda

但在最后一步之后，我开始收到以下错误：

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 cuda-drivers-450 : Depends: libnvidia-compute-450 (>= 450.51.05) but it is not installed
                    Depends: libnvidia-gl-450 (>= 450.51.05) but it is not installed
 libnvidia-decode-450 : Depends: libnvidia-compute-450 (= 450.51.05-0ubuntu1) but it is not installed
 libnvidia-ifr1-450 : Depends: libnvidia-gl-450 but it is not installed
 nvidia-compute-utils-450 : Depends: libnvidia-compute-450 but it is not installed
 nvidia-driver-450 : Depends: libnvidia-gl-450 (= 450.51.05-0ubuntu1) but it is not installed
                 Depends: libnvidia-compute-450 (= 450.51.05-0ubuntu1) but it is not installed
 nvidia-utils-450 : Depends: libnvidia-compute-450 but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

你能告诉我如何解决它，我已经尝试过apt --fix-broken install了，但它没有用，提前谢谢。

我有许多扩展名的文件*.launch分布在父目录内的不同文件夹中，文件的层次结构并不总是相同的.launch。即：src/folder/sth.launch和src/folder2/../../another.launch，所以这个解决方案在这里不起作用！

如何使用 Linux 命令在不同文件夹和级别的所有这些文件中将一个字符串替换为xarco.py另一个字符串？提前致谢。xarco*launch

• 我正在使用 Ubuntu 16.04 ros:kinect容器的 docker 映像。
• 我的问题是，当我通过 升级 pip 2.7（python 版本Python 2.7.12）时，每当我点击终端sudo pip install pip --upgrade时，它就开始显示以下错误：$ pip

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 7, in <module>
    from pip._internal.cli.main import main
  File "/usr/local/lib/python2.7/dist-packages/pip/_internal/cli/main.py", line 60
    sys.stderr.write(f"ERROR: {exc}")
                                   ^
SyntaxError: invalid syntax

你能告诉我如何解决这个错误吗？

在我的 Ubuntu 18.0.4 LTS 上安装 ROS Melodic，我按照一些安装说明进行操作，之后，每当我启动终端或更改为 root 时，我都会收到此消息sudo -s

Reading: command not found
Building: command not found
Reading: command not found

请问我该如何解决？
