module 'matplotlib.pyplot' has no attribute 'tight_layout'

For some reason the tight_layout() function from pyplot stopped working on machine. I've been using it in one of my programs for months and its decided to stop working out of the blue (I realize I probably made an accidental change somewhere that's caused this but I don't know where it would be). Any other matplotlib or pyplot function works a-okay, but whenever I call tight_layout I get

module 'matplotlib.pyplot' has no attribute 'tight_layout'

Which is obviously not true.

For example, even this code coming from the offical tight_layout guide (https://matplotlib.org/users/tight_layout_guide.html)

from matplotlib import pyplot as plt

plt.rcParams['savefig.facecolor'] = "0.8"

def example_plot(ax, fontsize=12):
     ax.plot([1, 2])
     ax.locator_params(nbins=3)
 ax.set_xlabel('x-label', fontsize=fontsize)
 ax.set_ylabel('y-label', fontsize=fontsize)
 ax.set_title('Title', fontsize=fontsize)

plt.close('all')
fig, ax = plt.subplots()
example_plot(ax, fontsize=24)
plt.tight_layout()

will produce the error.

I've reinstalled the matplotlib package a couple times and reinstalled my IDE (Spyder) to no avail. I'm pretty clueless at this point so any input would be great.

When you attempt to import Matplotlib and use tight_layout like a function, this error occurs. So you can fix your error by changing your import Matplotlib as plt to import Matplotlib.pyplot as plt.

I don't think some module will suddenly loose its methods. You may check for the method being in the code, 

import matplotlib.pyplot as plt
with open(plt.__file__[:-1],"r") as f:
    for line in f:
        if "tight_layout" in line:
            print(line)

This should result in two lines being printed. 

def tight_layout(pad=1.08, h_pad=None, w_pad=None, rect=None):
# and 
fig.tight_layout(pad=pad, h_pad=h_pad, w_pad=w_pad, rect=rect)

If this is not the case, check when the file was last changed 

import os
from datetime import datetime

f = datetime.fromtimestamp(os.path.getmtime(plt.__file__[:-1]))
print("Modification time: {}".format(f))

and compare to any actions you took, installing, uninstalling, modifying code etc.
