[Tutor] Using the Nimblenet Library in Python 3.6
Hello, I am running into some trouble when trying to import certain modules; I wanted to know if it is possible to use Nimblenet and all it's associated packages with Python3.6. From what I have read, that library is compatible with Python2.7. Some how I was able to successfully import Nimblenet on through the Conda prompt. But when I try to import some associated packages, it errors out. Here is an example: from nimblenet.activation_functions import tanh_function from nimblenet.learning_algorithms import scaled_conjugate_gradient from nimblenet.cost_functions import sum_squared_error from nimblenet.data_structures import Instance from nimblenet.neuralnet import NeuralNet import numpy as np import time import cPickle as pickle import logging from tabulate import tabulate import database_operations as dbo --- ModuleNotFoundError Traceback (most recent call last) in () 3 from __future__ import print_function 4 from nimblenet.activation_functions import tanh_function > 5 from nimblenet.learning_algorithms import scaled_conjugate_gradient 6 from nimblenet.cost_functions import sum_squared_error 7 from nimblenet.data_structures import Instance C:\Anaconda3\lib\site-packages\nimblenet\learning_algorithms\__init__.py in () 1 #from generalized_hebbian import * > 2 from scaled_conjugate_gradient import scaled_conjugate_gradient 3 from resilient_backpropagation import resilient_backpropagation 4 from scipyoptimize import scipyoptimize 5 ModuleNotFoundError: No module named 'scaled_conjugate_gradient' I would appreciate any help I can get!

"There should be one-- and preferably only one --obvious way to do it.": 1-str.format 2-% interpolation 3-string.Template 4-f strings -... I think that at least a few of these methods should become deprecated. Maybe 2 and 3? (though I use 2 all the time!). Not sure about 4. A proper templating language like Jinja might be more desirable to have in the standard library, addition to a simple string substitution mechanism ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I think you just answered your own question. If the package is designed for v2.7 its extremely unlikely to work in 3.6 even if you did succeed in importing it. The differences between 2.7 and 3.6 are significant. But this forum is the wrong place to ask. We are focused on the Python language and standard library. For detailed info you really need to ask the nimblenet developers/support fora. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.amazon.com/author/alan_gauld Follow my photo-blog on Flickr at: http://www.flickr.com/photos/alangauldphotos ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

So you may get some joy from asking in the Anaconda forums as well - the whole reason for existence of the Anaconda distribution is to make it reasonable to install things to do with Numerical and Scientific Python without some of the headaches sometimes associated with doing so from scratch - you seem to be trying the conda route, so maybe someone has blazed the trail before you? Also this is more supposition, but the fact that the line 3 from __future__ import print_function appears in the traceback means it's at least _possible_ Python 3 compatibility of the package has been considered - that's one of the most obvious and visible changes, that print becomes a function instead of a statement, and that was added to the future module somewhere along the line in the Py2 series. Best of luck in your searches! ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

I think you just answered your own question. If the package is designed for v2.7 its extremely unlikely to work in 3.6 even if you did succeed in importing it. The differences between 2.7 and 3.6 are significant. Python 3.6 has more functionality than 2.7 by definition, but your comment implies, at least to me, that 2.7 and 3.6 are chalk and cheese. Nothing could be further from the truth and has regrettably been one of the reasons for the dreadfully slow uptake of Python 3. -- My fellow Pythonistas, ask not what our language can do for you, ask what you can do for our language.
