chore: add python interpreter demo

3

## The basics This is a [proof-of-concept demo](https://alicialics.github.io/blockly-samples/) to add a Python Interpreter, which is almost identical to JS-Interpreter demo (in terms of both UI and code) minus the backwards-execution...

## The basics This PR will address issues like bundling assets (specifically tested with png files in @blockly/block-test) in webpack UMD bundles, as well as potential future plugin ESM builds....

Embedding Projector: UMAP and TSNE projections broken for embeddings that are not normalized

5

Chrome 111.0.5563.64 ## Issue description When using embeddings that are not normalized and sphereized, the UMAP and T-SNE are incorrect or not simply loading. See #5547 for a previous bug...

## Motivation for features / changes OrbitControl in Embedding Projector is not working. The current code is noop (because of a different Three.js version?) That means that: 1. 2D mouse...

## Motivation for features / changes Fixes #6271 Fixes #5547 ## Technical description of changes the reason is that knn [expects normalized vectors](https://github.com/tensorflow/tensorboard/blob/dc4754cf27d55c289b85a5ae77591f8d96fb682b/tensorboard/plugins/projector/vz_projector/data.ts#L478) for cosine distance (cosDistNorm) rather than arbitrary...

## Motivation for features / changes Supervise with parameters are only applicable to t-SNE projection. This moves it from data panel to projections panel, and simplifying code in the process...

## Motivation for features / changes If projection is switched from t-SNE to UMAP, t-SNE doesn't pause and the framerate would crash (5fps on M1 pro) If projection is switched...

* Motivation for features / changes Splitting an arbitrary vector into 256 parts hurts performance. This change speeds up KNN computation by 3x-5x. The splitting needs to be done before...

Embedding Projector: perform consistent knn calculation

## Motivation for features / changes Remove limitations on firefox when running embedding projectors Using GPU-accelerated tensorflow.js to compute knn speed up computation time for firefox on M1 Pro from...

## Issue description In general projection parameter updates are inconsistent especially for t-SNE/UMAP ### 2D/3D mode 2D/3D mode in t-SNE/UMAP simply makes the scatterplot a 2D/3D view. This is inaccurate...
