我不知道你是否要这样的结果，但是你的fwgt['hgt']我是不能理解的，你的标签里没有hgt这一项，下面我大概做了一下'Whole'的分布：

import numpy as np
import pandas as pd
import seaborn as sns
from scipy.stats import norm
import matplotlib.pyplot as plt


feature_names =['sex','Length','Diam','Height','Whole','Shucked','Viscera','Shell','Rings']
abalone_data = pd.read_csv('https://archive.ics.uci.edu/ml/machine-learning-databases/abalone/abalone.data', names = feature_names)
df=abalone_data

mwgt = df[df['Whole'] == 1]
fwgt = df[df['Whole'] == 0]
fwgtmean = fwgt['Whole'].mean()
fwgtsd = fwgt['Whole'].std()

fght_hist = sns.distplot(df['Whole'], norm_hist=True, kde=True, color='purple', bins=110)
x = np.arange(0, 1)
y = norm.pdf(x, loc=fwgtmean, scale=fwgtsd)
fght_hist.plot(x, y, 'purple')
plt.show()

如果你觉着有用，请采纳，谢谢！
