[Opengrads-users] PyGrads Installation problem + CENTOS 7

[Cristian F. <feb...@gm...>]

Dear opengrads users,

I am trying to install PyGrads in centos 7 without success, the current
error is as follows:

****
  File "setup.py", line 21
    print("ERROR: bdist_wininst must be run alone. Exiting.",
file=sys.stderr)
                                                                  ^
SyntaxError: invalid syntax
****

Current versions,
OpenGrads: 2.2.1.oga.1
Python: conda activated (3.6.7)

Could you guide me through the installation procedures?

Thanks in advance.

[Opengrads-users] Update to include fix for Day of the Week bug.

[Mike D. <mw...@gm...>]

Is there a plan to update Opengrads with the new Day of the Week fixes that
were implemented in the latest Grads updates ?

Thanks.

[Syed A. A. B. <ahs...@gm...>]

Dear All

NCEP servers recently changed to HTTPs while grads 2.2.1 offered for Linux

[Opengrads-users] OpenGrads PATH error on Windows 7 64-bit Professional

[Jonathan B. <jon...@gm...>]

I'm running Windows 7 Professional 64-bit on a laptop and when I try
to use any of the OpenGrads utilities, such as opengrads, I receive
this error :

"
MAX_SIZE = 2048, needed size = 2834
Internal error: environment variable PATH is too long; change MAX_SIZE
to at least 2834 and recompile or else shortten your PATH by 786
characters
"

Is there any way to make OpenGrads functional other than re-compiling
or reducing the number of characters in my PATH?

Thank you and regards,

Jonathan Busby

[Opengrads-users] Working through OpenGrADS Examples

Any ideas as to what might be wrong? Thanks.

Re: [Opengrads-users] Installation of GrADS and PyGrADS

[brown w. <gr...@ya...>]

Somewhat of an update. I place opengrads in /opt/opengrads. I set up the following environament variables:

export GABIN=/opt/opengrads/Contents/Linux/Versions/2.0.1.oga.1/x86_64
export GAUDXT=$GABIN/gex/udxt
export LD_LIBRARY_PATH=$GABIN/gex:$LD_LIBRARY_PATH

That pretty much breaks everything. Whereas before I was at least able to start PyGrADS, now it complain that matplotlib and pygtk aren't installed. If I remove those variables st least I can get into PyGrADS.

 I have been asked by a user to install both GrADS and PyGrADS. 

The testing of the software works, up to certain point:

 [4] ga-> . draw title Surface Temperature (Kelvin)


Until I execute:
ga-> dd ts

GrADSError: 'IPC extension not available - cannot import!'

I found that I am missing the extensions. My question is where should these extension be placed so
 that PyGrADS will find them?

[Opengrads-users] how to manipulate the grads internal pictures directly?

[Qian H. <yor...@gm...>]

Hi everyone,
I am currently developing a GUI program to show meteorological fields. My
solution is wxpython＋pygrads. I am planning  to use pygrads to generate
 pictures, and then load the pictures into the GUI using wxpython. I think
this isn't the best solution, and wondering is there anyway to manipulate
the gards internal picture objects directly, so i don't need to save the
pictures with commands like printim first.
Thanks!

[Opengrads-users] opengrads issue

[Litta A J <li...@gm...>]

Dear all,
I have tried both opengrads bundle in my system. The system is in 32 bit.
So first I downloaded the following bundle from their site and tried to
install in my system.
 *grads-2.0.1.oga.1-bundle-i686-glibc2.5-linux-gnu.tar.gz*

I have properly installed as specified in the document. I got the following
lines after try to use grads
 [root@nsg-corporate-059 ~]# grads
 Welcome to the OpenGrADS Bundle Distribution
--------------------------------------------
For additional information enter "grads -h".
 Starting
"/home/Model/SOFT/grads-2.0.1.oga/Contents/Linux/Versions/2.0.1.oga.1/i686/grads
" ...
[root@nsg-corporate-059 ~]#
Its properly detecting the path. But the command prompt is not coming. So I
tried next opengrads bundle
 *grads-2.0.1.oga.1-bundle-x86_64-glibc2.5-linux-gnu.tar.gz*
Then I got the following lines
[root@nsg-corporate-059 TAR_FILES]# grads

grads: missing required directory

 </home/Model/SOFT/grads-2.0.1.oga.1/Contents/Linux/i686>

     ---> at /home/Model/SOFT/grads-2.0.1.oga.1/Contents/grads line 165.
[root@nsg-corporate-059 TAR_FILES]#

I dont understand the issue? 32 bit opengrads version is working.. But the
command prompt is not coming when I type grads/opengrads commands. Please
help me..
best regards,
Litta

[Opengrads-users] pygrads problem

[wan A. <ard...@gm...>]

Hi, I am Wan Ardie, I have just downloaded and installed pygrads, with the
command:
*python setup.py install*
and targeted to a local directory.
I assume install is successful as there is no error, but when i try a few
lines as suggested at the link (
http://opengrads.org/wiki/index.php?title=Python_Interface_to_GrADS):
*from grads.gacore import GaCore ga = GaCore(Bin='gradsc')* i get a blank
GrADS display window and no further chance to enter at the prompt (unless I
use ctrl-C to quit the display window)
...
I have checked the gradsc is in my path,
I have also tested my grads without python, and it worked perfectly...


I would really appreciate the help, as this will me and my lab mates
(hopefully)

[Opengrads-users] OpenGrADS User Contributed Extensions problem

[Jagannathan R. <rje...@ya...>]

Hello,

I am using Grads 1.9b4 in Intel MAC book OSX 10.5.8 downloaded from  http://grads.iges.org/grads.
