unable to build the notebooks

[Thomas-Ulrich]

Hi,

For some reason (we were trying to create a new seismology exercise derived for rupture_2D), I tried to build the notebooks. And it turns out that I cannot build them.

Here is what I did:

pip install virtualenv
python -m venv envSeismoLive
source envSeismoLive/bin/activate
pip install --upgrade pip
pip install numpy
pip install scipy matplotlib jupyter jupytext nbconvert obspy pandas seaborn
python conf/convert_to_ipynb.py notebooks built_notebooks

(Python 3.7.4)

and here is what I get:

Any idea what could be the problem? Seems like a problem in obspy?

[krischer]

Hi Thomas,

this bug is due to newer numpy versions no longer accepting floating point numbers in the np.linspace call for the number of desired array elements.

This has to be changed in the whiten() function in the Ambient Seismic Noise/NoiseCorrelation notebook.

[Thomas-Ulrich]

ok thx, I can write a pull request.
Next error:

I guess this notebook was written for basemap.

[krischer]

Hmm - what is your basemap version?

Edit: Sorry not basemap but cartopy.

I feel like this should work.

[Thomas-Ulrich]

0.18.0

[krischer]

@megies Do you know what's going on here?

[Thomas-Ulrich]

Just wanted to see if I can complete the build to the end using basemap:
But no, I get another error (time-out?).

[krischer]

You can try to increase the timeout in the script: just set --ExecutePreprocessor.timeout=600 to something higher.

[Thomas-Ulrich]

no it does not work. Tried with --ExecutePreprocessor.timeout=6000000000

[megies]

@megies Do you know what's going on here?

sorry, never seen that and still doing most of my stuff in basemap.. slow on the transition 😊
