Hi everyone; I am using nupic with python on my custom anomaly detection, Now I am facing issue with using nupic_output.py file ploting and file writting…
I used nupic_output.py from oneHotGym example as well as sine_prediction example…
Thanx in advance for your help…
what kind of issue is ?

That file for the example depends on matplotlib being installed properly on your computer. Sometimes you need to figure what to do in your environment to properly install / run matplotlib.
Thanx @rhyolight…
I would like to ask more specific…
so would you like to spacify the matplotlib version with a generic nupic_output.py file… That works for all sort of examples to wheather write to a file or plot… and mention a link to nupic_output.py
Thanx @rhyolight for your time…
Thnx @way-sal the error is something like this… while it is working with writing to a file

This call to matplotlib.use() has no effect because the backend has already
been chosen; matplotlib.use() must be called before pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.
The backend was originally set to ‘module://backend_interagg’ by the following code:
File “/home/wanclouds/PycharmProjects/HTM_real_data_anomaly/run.py”, line 3, in
import matplotlib.backends
File “/home/wanclouds/sine_prediction/venv/local/lib/python2.7/site-packages/matplotlib/backends/init.py”, line 16, in
line for line in traceback.format_stack()
matplotlib.use(‘TKAgg’)

I’m using matplotlib 2.1.0. Sorry I can’t help you out more. If you can’t get matplotlib working, you can use the write to file option and plot the results in another way manually.
Hey, I recommend running it outside your python virtual environment and see if it makes any difference. Are you running on OSX?
