numpy deprecation warning

[pavlis]

I'm getting the following error any time I run the current container:

/tmp/ipykernel_535579/2643044777.py:26: DeprecationWarning: `alltrue` is deprecated as of NumPy 1.25.0, and will be removed in NumPy 2.0. Please use `all` instead.

This is a well known warning but I do not understand how to find where it is happening since it seems this is coming from cached copy something is creating in jupyter/python. It is just a warning but we should address it. As far as I can tell it isn't causing any issues for now.

I think this is not our problem but obspy. At least during a debugging session I see the error pop up when it runs obspy's travel time calculator.
