main.c:(.text+0x17a): undefined reference to `pow'

这个错误提示表明您在代码中使用了 pow 函数，但是编译器无法找到该函数的实现。这可能是因为您没有正确链接 math 库。

您可以尝试在编译选项中加入 -lm 选项来链接 math 库，例如：

gcc main.c -o main -lm

另外，请确保您的代码中包含了 math.h 头文件，否则也会出现类似的错误。

这是一个关于Docker的错误信息，看起来是在启动容器时挂载文件出错了。容器试图将 "/data/my-redis-dump/dump.rb" 挂载到容器内的 "/var/lib/gems/2.5.0/gems/redis-dump-0.4.0/lib/redis/dump.rb"，但是在挂载时出现了问题。可能是因为指定的路径不存在，或者是文件类型不符合预期，比如试图将一个目录挂载到文件上，或者将一个文件挂载到目录上。建议检查一下指定的路径是否存在，并且是否符合预期的文件类型。

这个错误和之前的错误信息一样，都是由于安装nvidia-tensorrt包时出现了问题。建议按照之前的方式安装nvidia-pyindex和nvidia-tensorrt，即先运行以下命令安装nvidia-pyindex：

$ pip install nvidia-pyindex

然后再运行以下命令安装nvidia-tensorrt：

$ pip install nvidia-tensorrt

如果还是无法解决问题，可以尝试升级pip或者使用conda进行安装。
