Matplotlib '；浮动'；对象没有属性'；数据类型'；用于三维绘图

我正在尝试绘制3D曲面。我有3个阵列，每个1D。这些值是从excel工作表中提取的

当我运行这段代码时，我得到以下错误

C:\ProgramData\Anaconda3\lib\site-packages\numpy\lib\function_base.py in 
average(a, axis, weights, returned)
355     if weights is None:
356         avg = a.mean(axis)
--> 357         scl = avg.dtype.type(a.size/avg.size)
358     else:
359         wgt = np.asanyarray(weights)

AttributeError: 'float' object has no attribute 'dtype'

我以前用不同的值集尝试过这段代码，它工作得非常好。但由于某种原因，这套代码根本不起作用

数组中的

Y

数字似乎太大了。但不知道为什么它要与matplotlib 2.2一起工作

你可以把它们变成浮子让它工作

Y = np.array(Y).astype(float)

---

它在matplotlib 2.2.2上对我来说很好。生成类似于我看到的表面的Z形。我将检查我的版本并在需要时更新。谢谢你的回复。我很感激。显然，我有matplotlib版本3。我应该降级吗？我还没有尝试matplotlib 3，因此无法发表评论。等别人插手
