I downloaded the Source code (https://docs.obspy.org/tutorial/code_snippets/merging_seismograms.py)
from the page of “Tutorial » Merging Seismograms” (Merging Seismograms — ObsPy 1.3.0 documentation)
and ran it in my terminal and my jupyter notebook independently.
A). Run in my terminal: a message as “merging_seismograms.py:28: UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure.”
B). Run in my Jupyter notebook: error message shows at beginning is:
AttributeError Traceback (most recent call last)
Input In , in <cell line: 21>()
19 plt.subplot(4, 1, 4, sharex=ax)
20 plt.plot(st.times(), st.data, ‘r’)
—> 21 plt.show()
and the error message shows in the end is:
AttributeError: ‘NoneType’ object has no attribute ‘canvas’
I installed pyqt5 or replaced plt.show() with plt.savefig(‘filename.png’), but they didn’t help.
My question is: should I install something else to solve this problem? or should I change the code somewhere to solve the issue?
Any possible way to solve the problem is appreciated.
