所以,我有一个numpy字符串数组,我想用这个函数计算每对元素之间的成对编辑距离:来自http://docs.scipy.org/doc/scipy的 scipy.spatial.distance.pdist -0.13.0 /参考/生成/ scipy.spatial.distance.pdist.html

我的数组样本如下:

 >>> d[0:10]
 array(['TTTTT', 'ATTTT', 'CTTTT', 'GTTTT', 'TATTT', 'AATTT', 'CATTT',
   'GATTT', 'TCTTT', 'ACTTT'], 
  dtype='|S5')

但是,因为它没有'editdistance'选项,所以我想给出一个自定义的距离函数.我试过这个,我遇到了以下错误:

 >>> import editdist
 >>> import scipy
 >>> import scipy.spatial
 >>> scipy.spatial.distance.pdist(d[0:10], lambda u,v: editdist.distance(u,v))
