不支持數類型爲/：「海峽」和「浮動」

我有一點麻煩，在這裏認識此錯誤消息......不支持數類型爲/：「海峽」和「浮動」

我一直在使用上的一些sklearn機器學習工具我數據最近。我試着輸出剪影係數爲我的數據，使用下面的下面的代碼：

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陣列只是一個系列，我從一個CSV文件中讀取數字。它看起來是這樣的：

[[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]]

是獲取返回看來，這樣的錯誤消息：

Traceback (most recent call last):

    % metrics.silhouette_score(distmat_array, labels, metric='precomputed'))

    return mean(axis, dtype, out) 
TypeError: unsupported operand type(s) for /: 'str' and 'float'

我被困在理解的錯誤消息。我怎麼知道我出錯的地方？如果有人友善，我在這裏出了什麼問題？

好的......所以我真的找出問題出在哪裏。通過將「dtype」從「object」更改爲「float」，問題解決了...
