我有一点麻烦，在这里认识此错误消息......不支持数类型为/：“海峡”和“浮动”
我一直在使用上的一些sklearn机器学习工具我数据最近。我试着输出剪影系数为我的数据，使用下面的下面的代码：
distmat = []
for row in distmat_csv:
distmat.append(row[1:])
in_distmat.close()
distmat_array = np.array(distmat, dtype=object)
print distmat_array
out_metricsfile = open('Influenza A All Subtypes Human Strains %s in %s Clustering Metrics.txt' % (name1, name2), 'w+')
out_metricsfile.write('%s in %s Clustering Metrics \n' % (name1, name2))
out_metricsfile.write('Estimated number of clusters: %d \n' % n_clusters)
out_metricsfile.write("Silhouette Coefficient: %0.3f \n"
% metrics.silhouette_score(distmat_array, labels, metric='precomputed'))
out_metricsfile.close()
的distmat阵列只是一个系列，我从一个CSV文件中读取数字。它看起来是这样的：
[[0.000000 0.614841 0.613074 ..., 0.007067 0.007067 0.010601]
[0.614841 0.000000 0...., 0.616608 0.613074 0.611307]
[0.613074 0..000000 ..., 0.614841 0.611307 0.609541]
...,
[0.007067 0.616608 0.614841 ..., 0.000000 0.010601 0.014134]
[0.007067 0.613074 0.611307 ..., 0.010601 0.000000 0.010601]
[0.010601 0.611307 0.609541 ..., 0.014134 0.010601 0.000000]]
是获取返回看来，这样的错误消息：

我被困在理解的错误消息。我怎么知道我出错的地方？如果有人友善，我在这里出了什么问题？
