Python Windrose产生仿射数据库错误

Question

我在这里使用Anaconda2尝试一个简单的pythonwindrose示例Windrose Notebook Example。但是当运行下面的简单代码时，我会收到错误消息“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()

我正在努力理解我在网上找到的关于affine2dbase的信息，但我认为这可能是matplotlib安装的问题？以下是我正在使用的版本

    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

以下是windrose作为管理员安装的conda安装信息：

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

我希望您能提供有关如何修复windrose的信息，以便我可以运行基本示例，或者如何减轻仿射2D错误。谢谢

正如@fyberoptik所建议的，解决方案是在conda提示符中使用pip install windrose。虽然在anaconda提示符中看起来没有任何变化，但windrose现在绘制测试数据和我自己的数据

(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)
