在ubuntu上使用theano导入sidekit时出错

Question

我安装使用conda，终端给我一个关于GPU的错误，但我没有使用GPU。

---

>>> import theano
>>> import numpy
>>> import matplotlib
>>> import sidekit

这会引发以下错误：

Import theano

WARNING (theano.sandbox.cuda): The cuda backend is deprecated and will be removed in the next release (v0.10).  Please switch to the gpuarray backend. You can get more information about how to switch at this URL:

Theano警告不是你无法导入Sidekit的原因。

不会导入Sidekit，因为它无法找到libsvm库文件，Sidekit要求您手动安装。查看Sidekit guide和this问题以获得解决方案。
