<SYSTEM_TASK:>
Given the following text description, write Python code to implement the functionality described below step by step
<END_TASK>
<USER_TASK:>
Description:
 GUI creation and interaction in IPython
Step1:  A pop up will appear saying 
The kernel appears to have died and will restart automatically
In the terminal, you can also see the following message
QWidget
Step2:  
Step3:  Now, if you click the button, the callback will be called. 
And since Jupyter Notebook is awesome the output will be displayed in the cell's output area (Look at the output area for the previous cell!)
Automatic-connection-using-a-new-Qt-Console
IPython's Frontend Kernel Model
Step4:  Now the Jupyter QtConsole will be started by connecting to the ipython kernel that is already running.
You do not believe it?
Well just type the magic %whos to see the truth.
You can redisplay the button now!!
I prefer continuing to work in the notebook, so I will close the button and also the QtConsole.
Pay close attention to the message in the dialog box.
Back in the Notebook turf, you can redisplay the button and continue clicking.

Python Code:
%gui
from PyQt5 import QtWidgets
b1 = QtWidgets.QPushButton("Click Me")
Explanation: GUI creation and interaction in IPython
End of explanation
%gui qt5
from PyQt5 import QtWidgets
b1 = QtWidgets.QPushButton("Click Me")
b1.show()
Explanation: A pop up will appear saying 
The kernel appears to have died and will restart automatically
In the terminal, you can also see the following message
