我已经安装了paramiko模块.但是,当我尝试导入该模块时.我收到以下错误.

import paramiko
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

ImportError: cannot import name util

有谁知道如何解决这个问题？

我想用matplotlib模块获得3D图.以下是我的一些源代码.

(LTV,DTI,FICO) = readData('Acquisition_2007Q1.txt')
x = np.array(LTV)
y = np.array(DTI)
z = np.array(FICO)

fig = plt.figure()
ax = fig.gca(projection='3d')
Axes3D.plot_trisurf(x, y, z, cmap = cm.jet)

的x,y以及z是这样的:

array([56, 56, 56, ..., 62, 62, 62])
array([37, 37, 37, ..., 42, 42, 42])
array([734, 734, 734, ..., 709, 709, 709])

但是,我收到以下错误:

AttributeError                            Traceback (most recent call last)
<ipython-input-22-5c9578cf3311> in <module>()
      1 fig = plt.figure()
      2 ax = fig.gca(projection='3d')
----> 3 Axes3D.plot_trisurf(x, y, z, cmap = cm.jet)
