Question

我使用skillmetrics包编写了一个简单的代码来形成taylor digram。我使用python版本Python 2.7.12。代码如下： -

import matplotlib.pyplot as plt
import pandas as pd
import numpy as np
import skill_metrics as sm
fire=pd.read_csv('fire.csv')
PMfire = zip(fire['Date'],fire['PM_fire'],fire['Embassy_PM'])
#taylor_stats1 = sm.taylor_statistics('PM_fire','Embassy_PM','Date')
o= {"Data":fire['Embassy_PM'],'Date':fire['Date']}# form date and and embassy datas
p= {"Data":fire['PM_fire'],'Date':fire['Date']}# form  dictionary containg pm_fire and date
# Calculate statistics for Taylor diagram
    # The first array element corresponds to the reference series 
    # for the while the second is that for the predicted series.
taylor_stats1 = sm.taylor_statistics(p,o,'Data')
sdev = np.array([taylor_stats1['sdev'][0]])# Calculate standard deviation
crmsd = np.array([taylor_stats1['crmsd'][0]])#Calculate root mean square difference
ccoef = np.array([taylor_stats1['ccoef'][0]])# Calculate correlation coefficient
sm.taylor_diagram(sdev,crmsd,ccoef)#form taylor digram
plt.savefig('taylor.png')
plt.show()

但是，它给了我错误。错误如下： -

AttributeError: 'module' object has no attribute 'to_rgb'

Answer 1

to_rgb函数最近才添加到matplotlib.colors命名空间。您可能安装了较旧版本的matplotlib。尝试更新到最新版本的matplotlib。

Answer 2

这与ipykernel和matplotlib不兼容的两个工具库的版本有关。 AttributeError: 'module' object has no attribute 'to_rgba'

Answer 3

$ sudo pip install --upgrade matplotlib

Answer 4

尝试将matplotlib和numpy升级到最新版本

sudo pip3 install --upgrade numpy
sudo pip3 install --upgrade matplotlib

AttributeError：'module'对象没有属性'to_rgb'
