[Discuss-gnuradio] Need to install PyQt4.Qwt5

I am running CentOS, and am trying to run a flowgraph containing a “trigger rising edge event” block. In my attempt to understand this block, the Internet  directed me to the only descriptive page available: An attempt at a tutorial by the inventor of the block, at the following URL:




The page points to a flowgraph. In this flowgraph is a block “PyQT Complex Time Block” When I click on the “Go” icon of the GRC toolbar, I get the following error message:


“plotter_base.py", line 26, in <module>
    from PyQt4 import Qt, QtCore, QtGui, Qwt5
ImportError: cannot import name Qwt5


When I type $sudo yum install PyQt4, I am assured that I have the latest version of PyQt4 installed.

When I type $sudo yum install python-qwt5-qt4, I am told that there is no such package available.

When I type $sudo yum install python-qwt5, I am told that there is no such package available.


What can I do?
