Hide tick labels and offset in matplotlib

I have two subplots that share the same x-axis. I removed the xticklabels of the upper subplot, but the offset "1e7" remains visible. How can I hide it?

Here is the code I used :

import matplotlib.pyplot as plt
import numpy as np

plt.figure()
s1 = plt.subplot(2,1,1)
s1.plot(np.arange(0,1e8,1e7),np.arange(10))
s1.tick_params(axis="x", labelbottom=False)

s2 = plt.subplot(2,1,2, sharex=s1)
s2.plot(np.arange(0,1e8,1e7),np.arange(10))

I also tried s1.get_xaxis().get_major_formatter().set_useOffset(False), but it did nothing and I also tried s1.get_xaxis().get_major_formatter().set_powerlimits((-9,9)) but it impacted also the lower suplot.

An alternative is to use plt.subplots to create the subplots, and use sharex=True as an option there. This automatically turns off all ticklabels and the offset_text from the top subplot. From the docs:

sharex : string or bool

If True, the X axis will be shared amongst all subplots. If True and you have multiple rows, the x tick labels on all but the last row of plots will have visible set to False

import matplotlib.pyplot as plt
import numpy as np

fig, (s1, s2) = plt.subplots(2, 1, sharex=True)
s1.plot(np.arange(0,1e8,1e7),np.arange(10))

s2.plot(np.arange(0,1e8,1e7),np.arange(10))

plt.show()

I finally find the answer on https://github.com/matplotlib/matplotlib/issues/4445. I need to add the following line to my code :

plt.setp(s1.get_xaxis().get_offset_text(), visible=False)
