Missing Model Pickle Files (*.dpe.pkl) #4

Closed David-McKenna closed 4 years ago

David-McKenna commented 4 years ago

Hey Tobia,

Think I've hit a roadblock while trying to use your sample scripts. Running the pointing_jones.py script with the suggested parameters --

./scripts/pointing_jones.py print LOFAR LBA SE607 Hamaker 2012-04-01T01:02:03 60 1 6.11 1.02 60E6

Results in a stacktrace from a file not found error, it looks like the code path was introduced in 0.7 so there might have been a file or two not included in the release?

Traceback (most recent call last):

A quick scan through the commit history I can't find any references to the dreambeam/telescopes/LOFAR/data/ folder or any *.dpe.pkl files, so hopefully it's just a quick fix to distribute the files on your end.

Cheers

Hi David, the idea is to create these dual-pol element models at runtime (i.e. first time, then subsequently taken from cache). I think a fix is to just create a directory under the 'LOFAR/' subdirectory called 'data/' because it expects there is such a directory to store data. I have pushed a fix, that you could try.

Thanks!

Cheers Tobia, that seems to have solved this issue at least, but I've run into a new issue further down the execution stack unforetunately. I'll open a new issue with that, alongside a PR with another quick fix for a python2/3 error I've encountered
