In Eclipse, I tried import "matplotlib", but it didn't work.



Traceback (most recent call last):
File "C:UsersHunter-DesktopA_Cognitiveneural_networkstep_function.py",
line 2, in <module>
import matplotlib.pylab as plt
ImportError: No module named matplotlib.pylab


mycode is below



import numpy as np
import matplotlib.pylab as plt
def step_funtion(x):
return np.array(x>0,dtype=np.int)
x=np.arange(-5.0,5.0,0.1)
y=step_funtion(x)
plt.plot(x,y)
plt.ylim(-0.1,1.1)
plt.show


※I checked by Windows cmd "WHERE", and finally I gets result of exsist of matplotlib's file.↓

    pylab is generally discouraged. It wouldn't surprise me if they simply removed it in the meantime.

    @roganjosh No pylab still exists. It wasn't removed. It's discouraged, but many people like it, so it stays.

    @helpful Can you check if you can import matplotlib alone, import matplotlib ? If so, what does print(matplotlib.__version__) give? If not, you need to install matplotlib
