[PYTHON] I tried launching jupyter nteract on heroku server

Trigger

Using flask and heroku, I made various text mining / visualization web applications. One day, I get to know nteract.

nteract https://github.com/nteract/nteract https://blog.nteract.io/designing-the-nteract-data-explorer-f4476d53f897 I don't think it's a jupyter notebook with an automatic interactive visualization function.

"Oh, you can visualize this much with the same effort as displaying a pandas DataFrame. You have to try this. ... Don't fall if you use heavy data ... There may be some weaknesses, but if it is a web application, it can be visualized quickly when you want to do it from anywhere regardless of hardware. In a sense, it's more convenient than the more restrictive Google Colaboratory. "

So, I tried running nteract on heroku.

reference

• For some reason, there is not much information on nteract ...

For studying machine learning using Python, set up a Jupyter Notebook on Heroku's free frame so that you can run it from your smartphone and share it. https://qiita.com/G-awa/items/8530a10cb847e4080df3

Constitution

heroku: As an application server nteract: Start on heroku github private: As a file server

code

--Create and deploy the following files. It works if you open heroku open or the specified address. --Caution: Security-related processing such as passwords is excluded. It is highly recommended to add. --Note: github's privatete is used as a file server, but I will omit the explanation.

start_jupyter

#!/usr/bin/env bash
jupyter nteract --no-browser --ip=* --port=$PORT

$ cd xxxxxx
$ git init
$ heroku create xxxxxx 
$ git add .
$ git commit -m "first"
$ git push heroku master

Operation example

• Due to heroku specifications, created data and files will disappear after a certain period of time. If you have any files you need, don't forget to save them outside the heroku server.

In short, you may put mecab etc.

Next, let's change to nteract base ...

Similar visualization method between relatively long sentences such as patents: tfidf / cluster vis: tfidf-word2vec-clustering visualization 　https://qiita.com/kzuzuo/items/8a80d8974bf3a7db7e54

• I feel that Dash is good if it can be established as a single web application.
• The same thing can be done with jupyter notebook.
• Pandas-Bokeh seems to be another pandas-based interactive visualization method. https://github.com/PatrikHlobil/Pandas-Bokeh/blob/master/README.md
