%matplotlib qt5 runs but doesn't generate graphs












0















I was using this code on my Jupyter Notebook until yesterday and it was working fine:



%matplotlib qt
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.scatter(X,Y,Z,c='black')
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')


This morning, for no apparent reason, it started saying that there was an error with qt4 or something. After some research I installed qt5 and changed the first line of the code to "%matplotlib qt5" which now makes the code run without errors, but doesn't generate any graphs. If I take the 5 after qt I run into the message "Warning: Cannot change to a different GUI toolkit: qt. Using qt5 instead.". I can still plot graphs with "%matplotlib inline", but I wanted some interactivity. Any ideas why this is happening?

          It seems something got updated; but with the information available it's not possible to find out what it is. In any case, since you have pyqt5 installed you may use %matplotlib qt5. Then you probably just forgot to type plt.show()?



          %matplotlib qt5
          import matplotlib.pyplot as plt
          plt.plot([1,4,2])
          plt.show()


          Also make sure to restart the kernel if you change the interactive backend, and if in doubt, let the line %matplotlib qt5 appear before importing pyplot.
