我从源代码安装python 3.8.3，如何安装python头文件（devel文件）？

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

fig = plt.figure()
ax = fig.gca(projection = '3d')

x = np.zeros((2, 24), dtype = 'datetime64[h]')
x[0,  : ] = np.arange('2020-02-27', '2020-02-28', dtype = 'datetime64[h]')
x[1,  : ] = np.arange('2020-02-28', '2020-02-29', dtype = 'datetime64[h]')

y = np.zeros((2, 24), dtype = 'datetime64[D]')
y[0, : ] = np.array(['2020-02-27' for i in range(24)])
y[1, : ] = np.array(['2020-02-28' for i in range(24)])

z = np.zeros((2, 24))
z[0,  : ] = np.arange(24)
z[1, …
