tls 流量画像——直接使用图像处理的思路探索，待进一步观察

代码，示意了一个tls的数据内容：

import numpy as np
import matplotlib.pyplot as pyplot
# !!! If on the server, use following, comment show and you can just save figure !!!
# pyplot.switch_backend('agg')

a = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12])
b = np.reshape(a, (2, -1))
c = a.reshape(2, -1)
print(a)
print(c)

感觉还是有内在规律可以遵循的。
