Initial Request
----------------------------------------------------------------
Hi METplus Team,
Earlier this week I was having some trouble with installing METplus, so
Julie directed me towards installing METplus via Docker (which seems to
have gone well). I am now going through the tutorial and I seem to be
having trouble with the pcp_combine section of the tutorial.
I feel confused because I was able to do the first part once before, but
now I get the following error:
[root at c809940775d2 pcp_combine]# pcp_combine \
> -sum 20050807_000000 3 20050807_120000 12 \
> sample_fcst_12L_2005080712V_12A.nc \
> -pcpdir ${METPLUS_DATA}/met_test/data/sample_fcst/2005080700
DEBUG 2: Performing sum command: Init/In_Accum/Valid/Out_Accum Times =
20050807_000000/030000/20050807_120000/120000
DEBUG 2: Searching for 4 files with accumulation times of 030000 to sum to
a total accumulation time of 120000.
ERROR :
ERROR : search_pcp_dir() -> cannot open search directory:
/data/input/METplus_Data/met_test/data/sample_fcst/2005080700
ERROR :
And the same error when I try the second prompt:
ERROR : search_pcp_dir() -> cannot open search directory:
/data/input/METplus_Data/met_test/data/sample_obs/ST2ml
I also was unable to use ncview to do the next page of prompts; I think it
has to do with Docker and its GUI capability. Here is the error I received:
/usr/local/bin/ncdump: sample_fcst_12L_2005080712V_12A.nc: No such file or
directory
[root at c809940775d2 pcp_combine]# ncdump -h
sample_obs_12L_2005080712V_12A.ncNote: could not open file /root/.ncviewrc
for reading
Note: could not open file /root/.ncviewrc for reading
Error: Can't open display
I think that I am following the tutorial step-by-step, but maybe this has
to do with my inexperience with Docker? Any assistance would be much
appreciated!
Thanks,
Josh

Hi Josh,
I see you are having issues running the tutorial instructions in
Docker.
>From the errors you are receiving, my guess is that the input data is
not
available inside your Docker container. When you run this command from
inside the Docker container:
ls /data/input/METplus_Data
You should see a directory called met_test. If it is not there, then
you
will need to obtain the Docker data volume that contains this input
data
and mount it to the container using the "--volumes-from" argument.
>From a
terminal where you execute docker commands, run the following:
*docker create --name met_tool_wrapper
dtcenter/metplus-data:4.0-met_tool_wrapper*
This obtains the 4.0 met_tool_wrapper sample input data and creates a
Docker data volume named "met_tool_wrapper." You will need to add the
following argument to the "docker run" command to start up the Docker
container:
--volumes-from met_tool_wrapper
This will use the Docker data volume you created named
"met_tool_wrapper"
and mount the volume to your Docker container so that the data will be
available. If everything was done correctly, you should be able to run
the
"ls" command from above and see the directory called met_test.
Let me know if you continue to have issues.
Thanks,
George

Subject: METplus Tutorial Questions
From: Joshua Winslow
Time: Mon Jun 28 17:24:48 2021
Hi George,
Thanks for your response. I ended up just removing and redoing the
docker
container and that part of the tutorial worked.
I am now curious about the use of ncview, ncdump, and the plot-data-
plane
tool with ghostview.
When I try to use the following code :
ncview sample_fcst_12L_2005080712V_12A.nc &
ncview sample_obs_12L_2005080712V_12A.nc &
ncdump -h sample_fcst_12L_2005080712V_12A.nc
ncdump -h sample_obs_12L_2005080712V_12A.nc
I receive the error:
Note: could not open file /root/.ncviewrc for reading
Note: could not open file /root/.ncviewrc for reading
Error: Can't open display:
Error: Can't open display:
I think I am able to use ncview, as I am getting a sort of summary of
the
.nc file with dimensions, variables, and global attributes, but I feel
a
little bit confused as to why the other parts aren't working?
Secondly, the plot_data_plane function seems to work without an error
message, but none of the methods for viewing the plot produce
anything, all
giving error messages:
Ghostview
Unable to open the display.
Display
display: unable to open X server `' @
error/display.c/DisplayImageCommand/410.
Creating a .png
convert: unable to open image `display': No such file or directory @
error/blob.c/OpenBlob/2882.
convert: no decode delegate for this image format `' @
error/constitute.c/ReadImage/564.
Thanks for your continued help!

Subject: METplus Tutorial Questions
From: George McCabe
Time: Tue Jun 29 08:51:20 2021
Hi Josh,
The tools used to visualize the data are not available inside the
METplus
Docker container. I don't know that anyone has used Docker to run the
tutorial before, so we don't have all of the protocols in place for
completing these steps this way. You *could* potentially install those
tools inside the container instance, but I am not sure how well X11
windows
forwarding works via Docker. I think the preferred approach is to
mount a
local directory to your Docker container so that the output from
running
METplus commands are written back to your computer and you can view
them
from there. This assumes that the visualization tools are available on
your
machine. The Docker documentation has information on how to set up
these
mounts. Note that currently the METplus Docker containers are run as
root,
so if you are using WSL2 (on Windows) to run Docker, then you may run
into
some issues where you cannot remove the local files unless you have
root
privileges.
I will bring this up in a team discussion to see if any other
developers
have any suggestions. Let me know if you are able to get this to work
in
your environment or if you need any assistance getting it set up.
Thanks,
George

Subject: METplus Tutorial Questions
From: Joshua Winslow
Time: Fri Jul 02 14:38:56 2021
Hi George,
Thanks for your suggestions. I don't necessarily need to do the whole
tutorial, I mostly just wanted to learn about using METplus with
Docker so
that I can start using it for work.
Would you be able to describe how to use volumes or bind mounts so
that I
can get the data that I need into docker? Now that I have
METplus "installed", I think I just need to get my data into docker
before
I can get rolling with those on my team who are a bit more experienced
with
MET.
Hope you have a great weekend!
Josh

Subject: METplus Tutorial Questions
From: George McCabe
Time: Tue Jul 06 09:39:05 2021
Hi Josh,
Here is a webpage from the Docker documentation with info on how to
set up
bind mounts:
https://docs.docker.com/storage/bind-mounts/
Essentially you will map a local directory that contains your input
data to
a directory inside your Docker container (i.e.
/data/input/my_data_dir) so
that the data will be available to the processes inside the container.
I
would recommend setting up a read-only mount so that you don't
accidentally
remove or modify any input files on your local filesystem. If you set
up
the mount correctly, then you should be able to run "ls" on the data
directory inside the Docker container and see the input files.
Let me know if you have any issues getting that set up.
Thanks,
George

Subject: METplus Tutorial Questions
From: Joshua Winslow
Time: Thu Jul 08 15:27:51 2021
Hi George,
Thanks for pointing me there, I think I was able to mount what I need.
I am now trying to run plot_data_plane to start plotting some data and
I
have run into an error. I will attach an image of the error at the end
of
this email, but I am not sure why the system can't open the file? I
expected more of the problems to come with displaying the results, a
bridge
that I will cross when I get there.
Any thoughts on why I would be getting this error? I'm wondering if I
should turn off the read-only option in my mounting process?
Thanks for your help,
Josh

Subject: METplus Tutorial Questions
From: George McCabe
Time: Mon Jul 12 10:39:39 2021
Hi Josh,
The plot_data_plane command assumes that the user has read/write
access to
the directory they are in as it reads the input file from that
directory
and writes the output file to the same directory. If you specify a
full
path to the output file to write the file outside of the read-only
mounted
drive, then you should be able to create the output file. If you need
to
access the output file on your local machine, you can mount another
directory to Docker and write the output data to that directory. Yes,
you
can also change the current mount you have so that it is not read-
only, but
be careful that you don't accidentally change or remove any local
files
that you need to preserve.
Let me know if you continue to have issues setting this up. I will add
this
to my notes to mention in our internal tutorial discussion to consider
changing for the next version.
Thanks,
George
