使用 Jupyter Notebook 进行信号绘图

Question

I have been trying to plot a certain signal on python but it keeps giving me an error message I don't know how to solve it

from matplotlib import pyplot as plt
from matplotlib import style
import mysignals as Sig

style.use('ggplot')
style.use('dark_background')
f,pltr_arr=plt.subplots(3,sharex=True)

pltr_arr[0].plot(sig.lnputSignal_1KHz_15kHz,color='magenta')
pltr_arr[0].set_title('subplot 1',color='magenta')

pltr_arr[1].plot(sig.InputSignal_1kHz_15kHz,color='yellow')
pltr_arr[1].set_title('Subplot 1', color='yellow')

pltr_arr[2].plot(sig.InputSignal_1kHz_15lkHz,color='green')
pltr_arr[2].set_title('Subplot 1',color='green')

above is the code of what I tried and below is the error message

ModuleNotFoundError: No module named 'mysignals'

Answer 1

Your error is ModuleNotFoundError: No module named 'mysignals' .

This error occurred since there is no python module named mysignals.py in the same directory or in installed through pip (see pip list ).
