您可以使用spectrapepper来实现此目的：

import spectrapepper as spep
import matplotlib.pyplot as plt

# load sample data from library
x, y = spep.load_spectras()

# calculate the average spectra of the set
avg = spep.avg(y)

# plot the result compared to the data set
for i in y:
    plt.plot(x, i, lw=0.5)
plt.plot(x, avg, c='red', lw=1)
plt.show()
