Hey all,
I'm trying to find a way to measure CPU usage and other measurements in
some operation or flowgraph (the actual processes don't matter) and compare
it to the same operation done after using RFNoC to shift the operations to
a USRP. It seems like gr-perf-monitorx would be perfect.
Unfortunately, every time I run the script, one of two ImportErrors occurs.
The first involved PyQt4 and Qwt5 (fixed by installing from source). The
next is this:
Traceback (most recent call last):
File "/home/rich/Desktop/repos2/target/bin/gr-perf-monitorx", line 54, in
<module>
from gnuradio.ctrlport.GrDataPlotter import *
File
"/home/rich/Desktop/repos2/target/lib/python2.7/dist-packages/gnuradio/ctrlport/GrDataPlotter.py",
line 26, in <module>
from gnuradio.ctrlport.GNURadio import ControlPort

from .ttypes import *

line 9, in <module>
from thrift.Thrift import TType, TMessageType, TFrozenDict, TException,
TApplicationException
ImportError: cannot import name TFrozenDict
I've installed thrift 0.9.3 (because 0.9.2 is required for
gr-perf-monitorx) and then reinstallled GNURadio using pybombs (by updating
apache-thrift) to check if that resolved anything; I've also uninstalled
and reinstalled thrift using pip (which shows version 0.9.3). Running
"gnuradio-config-info --enabled-components" I can see "* thrift" on the
list, so I know that GNU Radio has found it. Nothing changed.
Finally, running python from my terminal, I can't find TFrozenDict within
thrift by using dir(thrift.Thrift). Does GNU Radio use a custom thrift, or
is there a better way to install and update?
Thanks,
Richard McAllister
PS-does gr-perf-monitorx support RFNoC blocks? Its not mentioned online,
but then, RFNoC is pretty new.
