我得到了ValueError：无法通过重新映射的形状[原始 - ＆gt;重新映射]播放操作数：（1000，）和请求的形状（1000,1）

Question

# In order to use the 3D plot, the objects should have a certain shape, so we reshape the targets.
# The proper method to use is reshape and takes as arguments the dimensions in which we want to fit the object.
targets = targets.reshape(observations,)

# Plotting according to the conventional matplotlib.pyplot syntax

# Declare the figure
fig = plt.figure()

# A method allowing us to create the 3D plot
ax = fig.add_subplot(111, projection='3d')

# Choose the axes.
ax.plot(xs, zs, targets)

# Set labels
ax.set_xlabel('xs')
ax.set_ylabel('zs')
ax.set_zlabel('Targets')

# You can fiddle with the azim parameter to plot the data from different angles. Just change the value of azim=100
# to azim = 0 ; azim = 200, or whatever. Check and see what happens.
ax.view_init(azim=100)

# So far we were just describing the plot. This method actually shows the plot. 
plt.show()

# We reshape the targets back to the shape that they were in before plotting.
# This reshaping is a side-effect of the 3D plot. Sorry for that.
targets = targets.reshape(observations,1)

XS和ZS的形状为（1000,1） 目标的形状为（1000），即使将其形状保持为（1000,1），我也会得到这样的新错误 attributeError：'line3d'对象没有属性'_verts3d'
