Dark Notebook theme looks and scales great. Would be nice to share it with the rest of the world ;-)

[@Wouterdobbels]

Just google jupyter-themes (it's an open source project on github). There's a few dark themes in there that look like this one. I use onedork, which looks close to the one the speakers use but it's not exactly the same.

[@alchemication]

Hello! Thanks for the suggestion. I am using jupyter-themes alright. It's just the ones I've used don't scale well and good look in presenting to execs using them... Still, they are much better than the default theme ;-)

[@MouldyCheesePie]

@@Wouterdobbels JupterLabs seems to have everything that JupyterNotebook does, and it has an in build dark theme

jupyterlabs authors are not going to support full ipython: github.com/jupyterlab/jupyterlab/issues/8415#issuecomment-627526479 and not going to support full js: github.com/jupyterlab/jupyterlab/issues/3748#issuecomment-390523455

JupyterLab has black theme for ipywidgets and bqplot. You can use voila and add a jupyter_config.json file with theme set to dark. Checkout his mybinder link: mybinder.org/v2/gh/ChakriCherukuri/mlviz/master?urlpath=voila%2Frender%2FIndex.ipynb

Very interesting library. Are any of the ipynb files shared? Where can I access them?

[@slawomirgontarek4213]

Hello, Great learning material. Is there any code on this GitHub or other place training available? If so, please to send the link. Without seeing this code, it is difficult to understand the entire lecture. Thank you in advance for the information. I am waiting on answer

[@chakricherukuri3450]

@Slawomir Unfortunately the notebooks are Bloomberg proprietary. Please look at the examples folder in bqplot on github.

@sudhan you can checkout github.com/ChakriCherukuri/mlviz and github.com/ChakriCherukuri/toronto-ml-summit for some examples of bqplot dashboards

[@senthilramalingam9500]

Awesome and it stimulates many visualization ideas. Thanks for the presentation.

[@christianpetrozza2681]

Does anyone else have the problem where the line 'from bqpwidgets import DataGrid' gives the error 'No Module named bqwidgets'

[@shankariyer8493]

The combined plotting part is well explained @ 9:10- 11:40. Where can one find similar scripts for this

[@dalicodes]

Challenge accepted Time to learn this thing called ipywidgets with bqplots

[@ranjeetrathaur9378]

Amazing explanation about that project .it's more helpful for everyone.Thanks!!

[@nutelina]

11:12 Py3.js still relevant today?

[@TheEverydayAnalyst]

How can we showcase this to the world? Instead of hiding them in jupyter notebooks. Do we need web framework like tkinter or django? Are your dashboards live anywhere?

[@chakricherukuri3450]

@Abhishek you can use voila to render these visualizations as codeless dashboards. Checkout mybinder.org/v2/gh/ChakriCherukuri/mlviz/master?urlpath=voila%2Frender%2FIndex.ipynb where I render widgets running in Jupyter notebooks as voila dashboards.

[@MarkJay]

How u get the dark theme applied to the widgets?

[@chakricherukuri3450]

@Mark you can use voila dashboards using dark theme. Checkout my repo of ML notebooks github.com/ChakriCherukuri/mlviz. You need to provide jupyter_config.json and set the theme to dark. The mybinder link to voila dashboards is mybinder.org/v2/gh/ChakriCherukuri/mlviz/master?urlpath=voila%2Frender%2FIndex.ipynb

Hi, the button to make single cell into full-screen looks very useful. How can I do that in Jupyterlab? Thanks for help!

[@chakricherukuri3450]

@Yunfei, sorry it's not available right now. But we'll try to add it to Jupyterlab soon

[@alfcnz]

@@chakricherukuri3450 that would be very nice. For the moment one can install github.com/scottlittle/expand-cell-fullscreen

Some ML examples can be found in my repo github.com/ChakriCherukuri/mlviz.

[@absar66]

Chakri....great presentation and great work done ...wish the notebooks could be shared..but alas...it’s proprietary...

[@chakricherukuri3450]

Thanks Absar. Yes unfortunately the notebooks are proprietary. Please check out github.com/ChakriCherukuri/mlviz. It's a repo where I maintain visualizations of ML algos. There are good examples there as to how to link widgets and build simple dashboards. I plan to add more examples and improve the documentation.

[@absar66]

Many thanks Chakri..

[@AayushSahni]

@@chakricherukuri3450 How can we get the widget while we are in the Jupyter Notebook? The idea is to render the code and visualize at the same time.
