Re: [ferret_users] Dear Ferret users, pyferret unable to display plot/image after installation



Dear Ferreters
G'day

So there is a way out of this problem but it is not the fix to the current version of pyferret installation with ubuntu 20.04 LTS. 

Here is the fix if you want to use the latest pyferret (7.64 version)

(1) go to the anaconda link https://anaconda.org/conda-forge/pyferret
(2) you can now see there is one command to install old version under cf202003
(3) so create a new ferret environment (I created FER but it can be a name of your choice) by...
conda create -n FER -c conda-forge/label/cf202003 pyferret ferret_datasets --yes
So, this will be version 7.5 and now you can test the plotting 
use coads_climatology
fill sst[l=1]
(4) after doing that you can now install the latest version of ferret (if you need the latest capacity of ferret updates of version 7.6) using the following command. 
conda create -n FERRET -c conda-forge pyferret ferret_datasets --yes

The purpose of doing this is now we have two pyferret environments. So in the latest pyferret (v7.6 FERRET) you can compute and by using version 7.5 FER you can plot your results. I hope this issue will be resolved in the upcoming release till then happy ferreting. 

Cheers, Saurabh

I am looking forward to seek help in the plots/figure display bug after installing FERRET (conda create -n FERRET -c conda-forge pyferret ferret_datasets --yes) on Ubuntu 20.04. The version that will be installed is 7.64 and shows the error as mentioned below.

FGD_GPL: no active window
FGD_GCLSQ: no active window

I also tried to install the under-development version of pyferret from ( conda create -n FERRET_DEV install -c conda-forge/label/pyferret_dev pyferret ferret_datasets --yes) but it give error "usage: conda [-h] [-V] command ...
conda: error: unrecognized arguments: pyferret ferret_datasets

I also installed python3-qtpy from sudo apt-get install -y python3-qtpy 

The version is python3-qtpy (1.9.0-3)]

Is there any solution to this problem?

Cheers, Saurabh

Hi Oluwaseun,

grdelWindowCreate: error when calling createWindow in pyferret.graphbind: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

That error might have something to do with the following:


(I wonder how the Ubuntu package of pyferret is related to the pyferret github https://github.com/NOAA-PMEL/PyFerret )
