[英]seaborn distplot loop lazy evaluation
I am using ipython notebook and trying to use the following function to export seaborn distplots.我正在使用 ipython notebook 并尝试使用以下函数导出 seaborn distplots。 It works just fine if I call the function and execute with only one variable at a time.
如果我调用函数并一次只执行一个变量,它就可以正常工作。 If I call the function in a loop, it continues to build on top of the distplot from the previous function call.
如果我在循环中调用该函数,它会继续在前一个函数调用的 distplot 之上构建。
My desired output would be for the function to output a new displot every time it is called in a loop.我想要的输出是函数每次在循环中调用时都输出一个新的 displot。 Is there a way to force evaluation or a new distplot?
有没有办法强制评估或新的 distplot?
def graph_extraversion (x):
file_name = "extraversion_" + str(x) + ".png"
sns_plot = sns.distplot(Personalities[Personalities.labels1 ==x].extraversion)
sns_plot = sns.distplot(df.extraversion)
fig = sns_plot.get_figure()
fig.savefig(file_name)
new_stat = Personalities[Personalities.labels1 ==x].extraversion.describe()
extraversion_drift = extraversion_median - new_stat[1]
drift = extraversion_drift / extraversion_std
if (drift >= 1) | (drift <= -1):
return "1 std deviation or more"
else:
return "Less than one std deviation"
This what is what the distplot looks like after one call这就是一次调用后 distplot 的样子
This is two calls later in a loop.这是循环中稍后的两次调用。
Again this works just fine with a single call and execution but when looped it keeps building.同样,这在一次调用和执行中工作得很好,但在循环时它会继续构建。
So this has to do with matplotlib and closing figures.所以这与 matplotlib 和结束数字有关。
additional code required is an import:所需的附加代码是导入:
import matplotlib.pyplot as plt
Then at the end of the func:然后在函数的末尾:
plt.close(fig)
This should help with any looping with both seaborn and matplotlib这应该有助于使用 seaborn 和 matplotlib 进行任何循环
