Re: [ferret_users] Pyferret crash

[Martin Schmidt <martin.schmidt@xxxxxxxxxxxxxxxxx>]

Lijo and Joseph,

your link seems to point to some commercial web, I do not need a car.

Otherwise: pyferret needs some requisites delivered from the python world for graphics. PyQtx is one of them.  It needs to be installed as a python module, otherwise pyferret cannot render graphics. When installing the pyferret binaries there is no chance to check if prerequisites are there. So the problem shows up later, when running ferret.

The problem should be fixed by installing a PyQt package suitable for your the python version. For python 2.7 it should be PyQt4. So, please install this package before using ferret. Hopefully this solves your problem.

The new snakes should require PyQt5.  The latest ferret release checks which version of PyQtx is installed and works with the later package. Anyway, the install instructions of pyferret should be followed, especially the remarks on required prerequisites are serious.

Good luck,
Martin

Hello!

       I once had the same issue. I guess I solved it by first building SIP and then downloading and building PyQt4. Otherwise, you can make life more simple by letting Anaconda install pyferret by doing(skip ferret_dataset if already existing and later point it to its location):

"conda create -n FERRET -c conda-forge pyferret ferret_datasets --yes"

More details on this can be found here
