CDO Magics plot in Python
Added by David RAGATOA almost 5 years ago
Hi all,
I am trying to use CDO Magics plot in jupyter notebook but I cannot find a way out.
i.e:
cdo contour,device="png" ECMWF_ERA-40_subset.nc ECMWF_ERA-40_subset
what will be the python cdo correct writing to insert device="png" in the line?
Thank you

hi David!
AFAIK notebook behave just like regular python scripts. Please post the python code so that we can debug it
cheers

Hello Ralf,
Thank you for your prompt answer.
There is no script. I am just trying myself to py-cdo because I couldn't compile cdo with parallel on my new installed fedora 30 with deepin environment.
I discovered I can use the py-cdo to multiprocess and I find it very good.
I am trying the environment with the different combinations and hit the wall on this one:
cdo contour,device="png" ECMWF_ERA-40_subset.nc ECMWF_ERA-40_subset
the python code gives:
cdo.contour(input = "ECMWF_ERA-40_subset.nc", output = " test")
but the default output is in .ps.
"device=png" can change the output to ;png file but cannot find how to add it in the python line.
Thanks, cheers

try this
cdo.contour('device=png',input = "ECMWF_ERA-40_subset.nc", output = "test")

Thank Ralf. It works perfectly. I'm a bit surprised, I tried it several times yesterday it didn't work.
Many thanks.

you can set
cdo.debug = Trueto see the internal CDO calls. could be helpful for debugging
cheers
