我想使用 sidekit 工具包进行说话者识别，并且我已经为Ubuntu安装了 libsvm ，我正在使用anaconda 3.5.当我尝试导入 sidekit 时，出现以下导入错误
I'm tyring to use sidekit toolkit for speaker recognition and I have installed libsvm for Ubuntu, I'm using anaconda 3.5. When I try to import sidekit I get following import error

推荐答案
几个月前我安装Sidekit时遇到了同样的问题.
I had the same problem when I installed Sidekit some months ago.
1:如果要将Sidekit用于不涉及SVM(gmm-ubm，i-vector等)的系统，则可以通过编辑__init__.py避免导入libsvm来避免此问题.就您而言，它位于此处:/home/shivam/anaconda3/lib/python3.5/site-packages/sidekit/__init__.py.在第140行上(在if libsvm_loaded:的正上方)添加libsvm_loaded = False，并且不会导入libsvm.
1: If you want to use Sidekit for systems that do not involve SVMs (gmm-ubm, i-vectors etc.), then you can avoid the problem by editing __init__.py to not import libsvm. In your case, it is located here:/home/shivam/anaconda3/lib/python3.5/site-packages/sidekit/__init__.py.Add libsvm_loaded = False on line 140 (right above if libsvm_loaded:), and libsvm will not be imported.
2:如果您希望能够制作基于SVM的系统(例如在示例脚本rsr2015_svm_gmm.py中)，则可以使用Sidekit 文档告诉您(在libsvm安装之后)将libsvm.so.2复制到.../python3.5/site-packages/sidekit/libsvm/.
2: If you want to be able to make SVM-based systems (such as in the example script rsr2015_svm_gmm.py), the Sidekit documentation tells you to (after libsvm installation) copy libsvm.so.2 into .../python3.5/site-packages/sidekit/libsvm/.
如果import sidekit仍然给出相同的错误，请检查.../python3.5/site-packages/sidekit/__init__.py的第125行，并确保其显示libsvm = CDLL(os.path.join(dirname, 'libsvm.so.2'))
If import sidekit still gives the same error, check line 125 of .../python3.5/site-packages/sidekit/__init__.py and make sure it says libsvm = CDLL(os.path.join(dirname, 'libsvm.so.2'))
请注意，如果要更新Sidekit，将替换__init__.py和.
Note that __init__.py and will be replaced if you are to update Sidekit.
