if I will run the same algorithm in the community version and in the official on the same data I will received the same result?
That is the intention. There have been changes to improve performance but the results should be the same. If you find you are getting different results please let us know. Some of the calling arguments or syntax may have changed slightly. Those changes should be recorded in API_CHANGELOG.md .
I see in the community version thier warning that not finish to transfer the code to python 3, but the python 2.7 are fully supported?
As code is being converted it is being moved from the nupic.py repository (which is a copy of the numenta’s nupic repository) into the nupic.py branch of the nupic.cpp repository. This is work in progress but we expect that python 2.7 should work. python 3.x should work on the code that has already been converted.
Oh, I just remembered, there is a problem with Python 2.7 running on Windows. There is no way that windows can load the python extension libraries built for python 2.7. This is a problem with MSVC compiler compatibility with the old python lib. Python 3.x should work.
