faceting_skymodel option fails

[Joshuaalbert]

I produced my own skymodel by combined all the sub bands of the direction independent high res models then using pybdsm with bbs_patches='source' to avoid sources that only pop up at fainter end and lower frequencies but it fails. The last line in the log file is:

INFO - factor - Using /net/para34/data1/albert/products/goods-n-prefactor-results/FullBand-Combined.skymodel as sky model for source avoidance and DDE calibrator selection (if desired)

[darafferty]

After printing that line, it tries to load the sky model (see line 568 of https://github.com/lofar-astron/factor/blob/master/factor/process.py) -- can you load it with lsmtool outside of Factor?

[Joshuaalbert]

Hey David sorry I just noticed your reply to this. I'll try when I'm back from travels Monday.

@darafferty it works but there is something wrong with it:

In [3]: lsmtool.load('FullBand-Combined.skymodel')

Also this is a different issue than #178.

Did you check if you are allowed to read and execute these files? And if the *.pyc files exists and you are allowed to read and execute them? And that they are newer than the *.py files?

[Joshuaalbert]

No I'm only able to read *.py and *.pyc files in that folder. Should I have +x access?

[AHorneffer]

Ah, not, execute access doesn't seem to be needed for these files.

Can you do:
import astropy.coordinates.angle_parsetab
from another python shell?

[Joshuaalbert]

I am able to import that.

[darafferty]

Looks a lot like the error here: https://github.com/voidlinux/void-packages/issues/1695

[darafferty]

Actually, I reread your earlier post and it could be that these really are warnings and not errors, as it does seem that lsmtool loads the sky model successfully. If that's the case, I don't know why it doesn't work inside Factor. Can you try it again with Factor, in case something changed since you ran it the first time?

[Joshuaalbert]

Now there are no issues... running that. There are several changes in the paracluster at leiden though. We had a fedora upgrade to 25, and the lofar software I'm sourcing is for 23. The lsmtool is most recent from github. Either way, this seems not to be an issue at the moment.

[darafferty]

OK. Reopen if there are still problems.
