It's very strange 'cause they should not have any difference.

Reproduce the import from /root/anaconda3/bin/ipython and compare it with the notebook environment described in the report. Start with fbprophet/forecaster.py and the traceback through matplotlib/pyplot.py, backend_tkagg.py, and tkinter; the reported failure is the missing libXdmcp.so.6. Done means the environment difference is identified and importing fbprophet works consistently in both contexts.
