AttributeError: module 'pyaf' has no attribute '__version__'

[jpalma-espinosa]

Hello! While replicating the tutorial on jupyter notebook, I encounter the following error

AttributeError: module 'pyaf' has no attribute '__version__'

in this piece of code

import pyaf.ForecastEngine as autof
# create a forecast engine. This is the main object handling all the operations
lEngine = autof.cForecastEngine()

# get the best time series model for predicting one week
lEngine.train(iInputDS = df_train, iTime = 'Date', iSignal = 'Signal', iHorizon = 7);
lEngine.getModelInfo() # => relative error 7% (MAPE)

I am sorry if this is a "must know" issue to solve, but digging into StackOverflow provided no clue.

ERROR OUTPUT

@jpalma-espinosa

Thanks for the bug report. This is a real new issue.

I will commit a fix in the few coming minutes, can you please do some test after reinstalling PyAF ?

[antoinecarme]

(possible) fix committed.

[jpalma-espinosa]

@antoinecarme Can dooooo

[jpalma-espinosa]

uhmmm...Interesting. Uninstalled and reinstalled from the repo pip install --upgrade git+git://github.com/antoinecarme/pyaf.git

Running it on Jupyter notebook gives error, while using it "offline" in spyder worked like charm.

[antoinecarme]

you have to restart completely your notebook

[jpalma-espinosa]

ups, my bad. Restarted and working on jupyter Thank you! =)

[antoinecarme]

Thank you too for the feedback.

Enjoy!!!!

closing.
