jupyter notebook 生成了图片，但下方显示<Figure size 1980x1500 with 0 Axes>，下载图片文件后是空白的

问题遇到的现象和发生背景

在jupyter notebook，调用seaborn和pyplot画散点图

问题相关代码，请勿粘贴截图

%matplotlib inline
import pandas as pd
import numpy as np
import seaborn as sns

df = pd.read_excel(r'D:\xxx.xlsx',
                  usecols = [1,2,3])
BcrBc, MrMs, Interval = df['Bcr/Bc'], df['Mr/Ms'], df['Interval']

import matplotlib.pyplot as plt
plt.style.use(['science','ieee','no-latex'])

fig,ax = plt.subplots(figsize=[6,5], dpi=300)
ax.set_xlim(0,10)
ax.set_ylim(0,.6)

scatter = sns.scatterplot(x = BcrBc, y = MrMs, hue = Interval, alpha = .6, marker = '.')
ax.legend(loc = [.75,.6])

ax.set_ylabel('M$_\mathregular{r}$/M$_\mathregular{s}$')
ax.set_xlabel('B$_\mathregular{cr}$/B$_\mathregular{c}$')

ax.axvline(x = 1.5, linewidth = .5)
ax.axvline(x = 4, linewidth = .5)
ax.axhline(y = .05, linewidth = .5)
ax.axhline(y = .5, linewidth = .5)

plt.text(.5,.542,'SD',fontsize = 12)
plt.text(2.4,.442,'PSD',fontsize = 12)
plt.text(6.8,.02,'MD',fontsize = 12)

plt.show()

plt.savefig('Day Plot.eps', dpi=300)

运行结果及报错内容

输出并保存图片后，图片（正常显示）下方出现“<Figure size 1980x1500 with 0 Axes>”，导出jpg,png,tiff,eps等文件并下载后都是空白

我的解答思路和尝试过的方法

尝试过在导入库前加 “%matplotlib inline”，但依然不行

我想要达到的结果

想要保存正常输出的eps等格式文件
