我在运行 Ubuntu 的 Nvidia Jetson nano 上运行此命令：
sudo pip3 install keras
我收到此错误：
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.

我做错了什么？？
答案1
在 Ubuntu 18.04 及更高版本中卸载 kerassudo pip3 uninstall keras并运行以下命令从默认 Ubuntu 存储库安装 keras。
sudo apt install python3-numpy python3-scipy python3-h5py python3-six python3-theano python3-yaml python3-keras
这是命令的长格式，用于显示哪些包作为 python3-keras 的依赖项安装。同一命令的简写形式为：
sudo apt install python3-keras
答案2
卸载 keras 并尝试安装依赖项（首先安装 scipy）
sudo apt-get install -y build-essential libatlas-base-dev gfortran
如果可能的话，安装所有内容纳米动物园按照他们给出的顺序，因为他们要求你先安装 tensorflow，然后再安装 keras。最坏的情况是尝试再次刷新并从 zoo 安装。
