metpy skewT 'Line2D' 对象没有属性 '' 错误

Question

我只是想设置一个代码来绘制 skewT 图，但是代码在第一次调用设置图发生率时立即失败

import matplotlib.pyplot as plt
from metpy.plots import SkewT
skew=SkewT()

给我以下回溯，这是最新 metpy 版本中的错误吗？（我刚刚升级）

我在

Python 3.9.9 (main, Nov 21 2021, 03:23:42) 
[Clang 13.0.0 (clang-1300.0.29.3)] on darwin

并使用

 metpy.__version__
'1.1.0'

Answer 1

这是由最近发布的 matplotlib 3.5 引起的。我们计划在 MetPy 1.2 中发布对此的修复，计划很快发布。

同时，作为解决方法，您需要降级到 matplotlib 3.4。
