When importing HierarchicalForecastEngine to perform forecast, cannot import HierarchicalForecastEngine from pyaf module. Error as showed below

@geniusnhu

Thanks for using pyaf.

What version of python, pyaf, jupyter etc are you using ? A copy-paste of the output of this script in your local system can provide all that :

Did some tests with a new Debian test user, installed pyaf, executed a jupyter notebook with a hierarchical model. runs OK.

You probably need to check :

1. If another/older pyaf is installed.
2. mix between python2 and python3 on debian (pip3 instead of pip ?)
3. There seems to be some issues with packages installed from notebooks (PYTHONPATH ? ) :

[geniusnhu]

Using Google colab. The error still appears. I was able to use with Google colab 3 weeks ago, but error appears when I run the notebook again yesterday. When I tried with anaconda Jupyter notebook, no error appeared though.

[antoinecarme]

Also switched to google colab, runs OK. strange!

Hi, @antoinecarme! I have faced a similar issue for ForecastEngine. The problem is related to the GIT installation. If we install pyaf via pip it works fine. But when we use git as a source, some files don't install, include Engines. Probably, you need to check the setup.py.

Thank you for a great lib!

[antoinecarme]

@piLigrym

Thanks a lot for the feedback.

Indeed these files are not copied when installing from git, which is wrong, My bad!.

I will double check the setup.py.

[antoinecarme]

@geniusnhu , @piLigrym

Just updated the master branch, Could you please check the install from git when you have some time ?

Thanks in advance

Antoine

[piLigrym]

@antoinecarme Now sub-packages don't install. Probably you need to add: packages=find_packages(include=['pyaf', 'pyaf.*']),

[antoinecarme]

Thanks again .... shot 2

[geniusnhu]

install using pip but got another issue

[antoinecarme]

Try the fully qualified name of the class :

lEngine = hautof.cHierarchicalForecastEngine()

[geniusnhu]

Yes, sorry. My fault! It works perfectly now.

[antoinecarme]

You are welcome. Hope you enjoy!

[antoinecarme]

Closing.

Will be officially available in release 2.0

[eoagustin]

This still not works for me. Tried both installation through git and pip but still to no use
