当我在ubuntu14.04中运行这段代码时，我想用scipy.spatial.distance计算数组的余弦距离。但是它在导入scipy.spatial.distance时抛出了一个错误。 import numpy as np
import scipy
from scipy.spatial.distance import pdist
x=np.array([[[-0.22008298, 0.28819615, 0.09895946, 0.16789497, 0.02379252,
-0.25700486, 0.1628186, 0.12296761, 0.01750283]],
[[ 0.29891527, 0.17249978, -0.10084602, -0.16522293, 0.06811064,
0.07434326, -0.19697316, -0.22199543, 0.07647966]],
[[-0.04112297, 0.13392878, -0.06575392, 0.0893533, 0.22577047,
0.00289264, 0.09996213, 0.17324321, 0.08673526]]])
B =x.transpose(1,2,0).reshape(-1,x.shape[0])
print(B.shape)
print (B.ndim)
#array.astype(int)
print(B)
y=1-(pdist(B, metric='cosine'))
print(y)它抛出了这个错误， Traceback (most recent call last):
