Python Windrose 产生 Affine2dbase 错误

Question

我正在使用 Anaconda2 从这里 Windrose Notebook Example 尝试一个简单的 python windrose 示例。但是当运行使用下面的简单代码

时，我收到错误消息'

TypeError: unbound method __init__() must be called with Affine2DBase instance as first argument (got Affine2D instance instead)

'

from windrose import WindroseAxes
from matplotlib import pyplot as plt
import matplotlib.cm as cm
import numpy as np

ws = np.random.random(500) * 6
wd = np.random.random(500) * 360
ax = WindroseAxes.from_ax()

我很难理解我在网上找到的关于 affine2dbase 的信息，但我认为这可能是我的 matplotlib 安装有问题？这是我使用的版本

    matplotlib                2.2.3            py27h263d877_0
    matplotlib-base           2.2.5            py27h6595424_1    conda-forge
    windrose                  1.6.7                      py_1    conda-forge
    ipython                   5.8.0                    py27_0

这是以管理员身份安装 windrose 的 conda 安装信息：

(base) C:\WINDOWS\system32>conda install -c conda-forge windrose

我将不胜感激有关如何修复 windrose 的意见，这样我就可以运行基本示例或如何减轻 affine2d 错误。谢谢

正如@fyberoptik 所建议的那样，解决方案是在 conda 提示符下使用 pip install windrose。虽然在 anaconda 提示中看起来没有任何变化，但 windrose 现在为测试数据和我自己的数据绘图。

(base) C:\Users\Student>pip install windrose
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

使用标准示例：

wd = np.random.random(500) * 360
ax = WindroseAxes.from_ax()
ax.bar(wd, ws)
