无法从linux上的pip安装libsvm。

Question

为此，我试图运行sidekit，因此需要安装libsvm，并且使用pip将得到以下错误。

尝试：pip安装libsvm，sudo pip安装libsvm和sudo -H pip安装libsvm。

Answer 1

libsvm是一个C++包，有一个python包装器。您首先需要安装libsvm包本身。

sudo apt install libsvm3

然后安装python包装器。

sudo apt install python-libsvm

如果您使用的是ubuntu，您可以使用突触包管理器。这样生活就容易多了。

编辑:对于旧版本的操作系统，如果你使用apt-get，使用apt-get而不是apt.

Answer 2

你试过吗

sudo pip安装libsvm

或

sudo -H pip安装libsvm

Answer 3

apt-缓存搜索libsvm

sudo apt-获取安装libsvm*

*=是搜索中的名字之一
