seaborn FutureWarning:将以下变量作为关键字参数传递:x, y [英] seaborn FutureWarning: Pass the following variables as keyword args: x, y

问题描述

我想绘制一个seaborn regplot.我的代码:

x=data['健康预期寿命']y=data['max_dead']sns.regplot(x,y)plt.show()

然而，这给了我未来的警告错误.如何修复此警告?

FutureWarning:将以下变量作为关键字参数传递:x、y.从 0.12 版开始，唯一有效的位置参数将是数据"，并且在没有显式关键字的情况下传递其他参数将导致错误或误解.

解决方案

• 从技术上讲，这是一个警告，而不是错误，现在可以忽略，如本答案底部所示.
• 我建议按照警告的说明进行操作，为

  # 指定 x, y 参数的绘图sns.regplot(x=x, y=y)# 或使用sns.regplot(data=pen, x='bill_depth_mm', y='bill_length_mm')

  忽略警告

  • 我不建议使用此选项.
  • 一旦 seaborn v0.12 可用，此选项将不可行.
  • 从 0.12 版本开始，唯一有效的位置参数将是 data，并且在没有显式关键字的情况下传递其他参数将导致错误或误解.

  导入警告warnings.simplefilter(action=ignore", category=FutureWarning)# 不指定 x, y 参数的绘图sns.regplot(x, y)

  I want to plot a seaborn regplot. my code:

  x=data['Healthy life expectancy']
  y=data['max_dead']
  sns.regplot(x,y)
  plt.show()
  

  However this gives me future warning error. How to fix this warning?

  FutureWarning: Pass the following variables as keyword args: x, y. From version 0.12, the only valid 
  positional argument will be 'data', and passing other arguments without an explicit keyword will 
  result in an error or misinterpretation.
  

  解决方案

  • Technically, it's a warning, not an error, and can be ignored for now, as shown in the bottom section of this answer.
  • I recommend doing as the warning says, specify the x and y parameters for seaborn.regplot, or any of the other seaborn plot functions with this warning.
  • sns.regplot(x=x, y=y), where x and y are parameters for regplot, to which you are passing x and y variables.
  • Beginning in version 0.12, passing any positional arguments, except data, will result in an error or misinterpretation.
    • For those concerned with backward compatibility, write a script to fix existing code, or don't update to 0.12 (once available).
  • x and y are used as the data variable names because that is what is used in the OP. Data can be assigned to any variable name (e.g. a and b).
  • This also applies to FutureWarning: Pass the following variable as a keyword arg: x, which can be generated by plots only requiring x or y, such as:
    • sns.countplot(pen['sex']), but should be sns.countplot(x=pen['sex']) or sns.countplot(y=pen['sex'])

  import seaborn as sns
  import pandas as pd
  
  pen = sns.load_dataset('penguins')
  
  x = pen.culmen_depth_mm  # or bill_depth_mm
  y = pen.culmen_length_mm  # or bill_length_mm
  
  # plot without specifying the x, y parameters
  sns.regplot(x, y)
  

  # plot with specifying the x, y parameters
  sns.regplot(x=x, y=y)
  
  # or use
  sns.regplot(data=pen, x='bill_depth_mm', y='bill_length_mm')
  

  Ignore the warnings

  • I do not advise using this option.
  • Once seaborn v0.12 is available, this option will not be viable.
  • From version 0.12, the only valid positional argument will be data, and passing other arguments without an explicit keyword will result in an error or misinterpretation.

  import warnings
  warnings.simplefilter(action="ignore", category=FutureWarning)
  
  # plot without specifying the x, y parameters
  sns.regplot(x, y)
