在 ubuntu 上使用 theano 导入 sidekit 时出错

Question

I had installed using conda and the terminal is giving me an error about GPU but I am not using a GPU.

---

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

And this throws the following error:

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:

The Theano warning is not the reason of why you can't import Sidekit though.

Sidekit will not be imported because it cannot locate the libsvm library file, which Sidekit requires you to install manually. Check out the Sidekit guide and this question for a solution.
