Hi Deanna,
I moved your question over from my inbox to met-help. I figured that
it may be of interest to other users.
I haven't had a chance to debug this specific issue yet. But I did go
searching through the user's guide and the slides from this week. I
wasn't able to locate a python example that was incorrect. But I do
realize that it would be easy to accidentally include "python" at the
front of this type of string:
'name = "mypythonscript.py";'
When you run directly on the command line, you start with 'python':
python mypythonscript.py
But when you run it through MET, you do not:
plot_data_plane PYTHON_NUMPY myplot.ps 'name="mypythonscript.py";'
If you do run across bad/misleading documentation. Please let me know
where and I'll be happy to fix it up.
I'll let you know when I have more info on this issue you're having.
Thanks,
John

Deanna,
OK, I was able to log on to tide and take a look at this. First, the
error you're getting was caused by a typo on your command line:
plot_data_plane PYTHON_NUMPY ncep_ice.ps \
'name="/marine/noscrub/Deanna.Spindler/METplus/METplus-
2.0/ush/read_ncep_ice_nc_met.py;'
You were missing a closing double-quote before the semi-colon at the
end.
So here's the commands I ran on tide:
# Load the MET module
module use /global/noscrub/Julie.Prestopnik/modulefiles
module load met/8.0
# Run your python script on the command line
python /marine/noscrub/Deanna.Spindler/METplus/METplus-
2.0/ush/read_ncep_ice_nc_met.py
# Try running it through plot_data_plane
plot_data_plane PYTHON_NUMPY ncep_ice.ps \
'name="/marine/noscrub/Deanna.Spindler/METplus/METplus-
2.0/ush/read_ncep_ice_nc_met.py";'
But I get all sorts of python library errors. But this is NOT a
problem with your script. It's a problem with the python setup on
tide.
I tried running the simple "FCST" plot that I showed last week:
plot_data_plane PYTHON_NUMPY fcst.ps \
'name="/global/noscrub/Julie.Prestopnik/met/8.0/met-
8.0/scripts/python/read_ascii_numpy.py
/global/noscrub/Julie.Prestopnik/met/8.0/met-8.0/data/python/fcst.txt
FCST";'
But I got the errors listed below.
We need to get this script working well before asking you to proceed
with your testing.
Sorry about all the confusion.
Thanks,
John

Hello John,
Thanks for looking at my ice test and figuring out what is happening.
I
tried to get around the NCO installed python, but that gave a
different
error:
> module use /global/noscrub/Julie.Prestopnik/modulefiles
> module load met/8.0
> module unload python/2.7.14
> module load anaconda
> plot_data_plane PYTHON_NUMPY ncep_ice.ps \
'name="/marine/noscrub/Deanna.Spindler/METplus/METplus-
2.0/ush/ncep_ice.py";'
DEBUG 1: Opening data file: PYTHON_NUMPY
Fatal Python error: PyThreadState_Get: no current thread
Aborted (core dumped)
I think it also has to do with conflicting libraries, this time
between
METplus and the anaconda install of python 2.7.15.
I will wait until I hear from one of you before trying again.
Thanks again,
Deanna

Deanna,
Good news. Julie Prestopnik and I just debugged this issue. After
some
googling and testing we found the solution. We needed to recompile
MET
using the "-Xlinker export-dynamic" flag. That makes python happy.
Julie is recompiling met-8.0 on tide now, and it's ready for you to
test.
I reran your plot_data_plane command. I got an error about embedded
spaces... so I changed the "level" string in your script from "mean
sea
level" to "msl". Then finally, it was happy and produced the attached
plot.
Looks to me like the data is upside down in the domain. That should
be
fairly easy to fix in your python script, re-ordering the data.
Thanks for your patience and being our guinea pig for this new
functionality!
John

Hello John,
I have a new script in the same directory: ncep_ice.py
It flips the ice field, uses the nc attributes that are defined in the
data, and replaces all blanks with under-scores.
I just tried it, and got a new error:
> plot_data_plane PYTHON_NUMPY ncep_ice.ps \
'name="/marine/noscrub/Deanna.Spindler/METplus/METplus-

Subject: read_ncep_ice_nc_met.py
From: John Halley Gotway
Time: Wed Oct 10 11:39:10 2018
Deanna,
Good news. I have a fix for you to try. In your script, ncep_ice.py,
please try replacing...
met_data=ice[::-1,]
with this...
met_data=ice[::-1,].copy()
Why would that fix it? When you do an assignment in python "a=b",
apparently it does a shallow copy instead of a deep copy. That means
that
"a" is just another reference to the memory pointed to by "b". So "a"
and
"b" both point to the same underlying python object. Using "a =
b.copy()"
forces a deep copy... meaning "a" and "b" point to different places in
memory.
I can't fully explain *why* the shallow copy doesn't work well in MET
when
array re-ordering has occurred. But it appears that the deep copy
makes
MET happy.
Please let me know if that fixes it.
Also, the segault is caused in MET by a NULL pointer that we've failed
to
check. I'll add a check for NULL and return and error message instead
of
segfautling.
Thanks,
John

Hello John,
Sorry for the delay getting back to you - I've been setting up a
validation
page for hurricane Michael.
I made the edit you suggested to ncep_ice.py, and plot_data_plane now
works. I get a long thin vertical plot though.. any way of getting it
to
print horizontally? just curious. But at least it's reading the data,
and
I think it's got the right values in the right places.
I guess my next step is to get it to read the RTOFS ice, and then copy
a
grid_to_grid example precip.conf file, and try to edit it and set all
the
paths correctly.
Thanks for helping me,
Deanna

From: John Halley Gotway

Deanna,
There really isn't a plotting orientation option for plot_data_plane.
It's
really only meant as a diagnostic rather than a fully featured
plotting
tool.
Looking at your data, it does strike me as odd that you have polar ice
data
on a lat/lon projection. Seems like a polar stereographic projection
centered over the north pole would be a more logical choice. Perhaps
NCEP
grid 171 for the Northern Hemisphere High Resolution Sea Ice grid
(Polar
Stereographic) (
http://www.nco.ncep.noaa.gov/pmb/docs/on388/grids/grid171.gif) would
be a
good choice. But I don't know the source of this data and whether or
not
that's an option.
As a test, I did the following:
(1) Used copygb to put a GFS GRIB record onto NCEP Grid 171:
> copygb -xg171 GFS.grb G171.grb
(2) Ran MET's regrid_data_plane tool to interpolate to that domain:
> regrid_data_plane PYTHON_NUMPY G171.grb ice_G171.nc -field
'name="ncep_ice.py";' -name ice
(3) Ran MET's plot_data_plane tool to plot the result:
> plot_data_plane ice_G171.nc ice_G171.ps 'name="ice";level="(*,*)";'
And I've attached png version of the result. Looks much easier to
interpret on this projection.
Thanks,
John
