does not have 'dataselect' and/or 'station' services

[ElodieK]

Hi there,

I'm using the mass downloader for earthquake: obspy.UTCDateTime(2011, 6, 12, 21, 3, 26) with IRIS and ISC clients however am getting these errors:

[2018-04-10 10:44:56,888] - obspy.clients.fdsn.mass_downloader - INFO: Cannot use client 'ISC' as it does not have 'dataselect' and/or 'station' services. [2018-04-10 10:44:56,888] - obspy.clients.fdsn.mass_downloader - INFO: Downloaded 0.0 MB in total.

Any suggestions please?

Thanks, Elodie

The ISC does not have a dataselect nor a station service (it only serves event meta information) so it cannot be used to download that data from them - so that message is expected (it also only states it as an INFO message). The mass downloader dynamically figures out the capabilities of each service - one of the requirements is that the service can server waveforms and station metainformation in the first place.

It usually does not hurt to just leave the providers keyword argument empty. It will then just use all providers it knows about.

It is not just the ISC, it's also IRIS which I've downloaded data from for other earthquakes in the past.

Can you paste the full error message? IRIS definitely has these services and it is usually very stable. Can you also paste the output of running this on the shell?

$ python -c "from obspy.clients.fdsn import Client; Client('IRIS', debug=True)"

Thanks. It is not a firewall issue on your side.

I assume there was a temporary internet connection problem at one point. Our internal fdnsws client caches service discovery so they are only discovered once within a python run. Can you restart ipython and run globaldata_afar.py again or just run python globaldata_afar.py on the shell? I think it should work then.

[ElodieK]

Yes, it's working- thanks a lot. Elodie

Great :-)

[ElodieK]

Hi,

I'm having the same problem. My internet looks fine and I'm re-opening python and still no download. Is the problem your side?

Thanks.

I'm pretty sure this is not ObsPy's fault. Does this:

python -c "from obspy.clients.fdsn import Client; Client('IRIS', debug=True)"

report discovered station + dataselect services? If yes then everything should work and there is some other issue. The mass downloader internally does the same.

[ElodieK]

Ah yes- found it.

Thanks again!
