missing attribute in lda2vec module in notebook

Question

A jupyter notebook cannot import dirichlet_likelihood.py from lda2vec.
This py file exists in github for the current lda2vec.

I installed the module and opened the workbook, then attempted to run it. I suspect there is a very simple reason for my problem.

The notebook is https://github.com/cemoody/lda2vec/blob/master/examples/twenty_newsgroups/lda2vec/lda2vec.ipynb

When I try the below at the python command-line (in the current environment) it does not give the below error and instead it wanted keras, which I installed. On the command line it says it cannot import preprocess.

python

Using TensorFlow backend.

EDIT

I got it work by doing these things - Get ubuntu-18.04.2-desktop-amd64.iso - Have BIOS virtualisation settings changed for hyper-V - Make a VM in VMWare - Increase memory to 3G - Give it 40G of disk

Then in a terminal

sudo apt install python2.7
sudo apt install python-pip
pip install virtualenv
Mkdir 2.7env
Cd 2.7env
python2.7 -m venv .env
python2.7 -m virtualenv .env
source .env/bin/activate
pip install --upgrade pip
pip install jupyter
pip install -U spacy
python -m spacy download en
pip install wheel nltk gensim pyLDAvis lda2vec
sudo apt install git
git clone https://github.com/cemoody/lda2vec.git
cp ~/lda2vec/build/lib.linux-x86_64-2.7/lda2vec/corpus.py ~/2.7env/.env/lib/python2.7/site-packages/lda2vec/Corpus.py
cp ~/lda2vec/build/lib.linux-x86_64-2.7/lda2vec/preprocess.py ~/2.7env/.env/lib/python2.7/site-packages/lda2vec/preprocess.py
python -m pip install ipykernel
python -m ipykernel install --user
python lda2vec/examples/twenty_newsgroups/lda2vec/lda2vec_run.py
cd lda2vec/examples/twenty_newsgroups/lda2vec/
jupyter notebook
change the kernel to 2

In firefox open lda2vec.ipynb

As above, I am now stuck trying to get it to re-create the twenty_newsgroups npz file so I can eventually provide my own content. In case anyone out there understands this better, I suspect trying to run this script on VM with little RAM might be the problem but the error is reported as

Answer 1

Alright I got this to work. The problems were

1. pick the right python to run a 4 year old git project. Python 2.7.
2. check the installed module has the code from the git repo
3. run through the problem in a python terminal
4. copy and edit python files go to 3

One problem above was to do with a changed API for a dependency. ImportError: No module named 'spacy.en' The original problem was likely due to something about git or python I am not familiar with. Still the git project self-tests all fail and its build fails. But I have my jupyter notebook running and producing convincing outputs.
