Hi,
a few days ago I had a similar problem. The mail-thread was named [ferret_users] build pyferret_v710.
Karl Smith helped me do sort out some misconfigured python installation.
Your error message shows that your python cannot load neither PyQt5 nor PyQt4. For python 2.7 it should be PyQt4, not PyQt5!
To check your python installation just issue
$ python2.7
$>>> import PyQt4
This should work without an error. I am not sure about anaconda, but I think in this case it should be PyQt5!
If this does not work, the ferret installation is not the error source but the python installation is the problem.
The next point is that the ferret-environment includes pythen-related variables.
env | grep PY
gives for me
PYTHONSTARTUP=/etc/pythonstart
PYFER_EXTERNAL_FUNCTIONS=/sw/viz/ferret/py_ferret_v700_ub_ py_27/ext_func/pylibs
PYTHONPATH=/sw/viz/ferret/py_ferret_v700_ub_py_27/lib/ python2.7/site-packages
Finally, Karl points to a stand-alone check of the ferret graphics machine:
source your ferret environment (do not forget this!)
$ cd $FER_DIR/lib/python2.7/site-$ python2.7 pipedviewerpq.pypackages/pipedviewer/
(This will display a little dialog box with a button. Every time you press the button it will print a drawing command to the terminal as well as issue that command to the viewer. It should display a window, draw various things to that window, save the final plot as a PDF and PNG, and exit.)
The scripts around pipedviewerpq.py try to load PyQt5, if this does not exist PyQt4 and end with an error if none of them is found.
Hope this helps, to proceeed.
Greetings,
Martin

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
