Redrawing of the Graphviz decision tree by @standage (rendered using http://magjac.com/graphviz-visual-editor).

• Output:
  

• Code:

Main bash script:

• Note: this is a work around for using linux scripting (grep/sed/awk) via WSL2 on an Windows OS target (../../mnt)
  ...without installing anything.

Contents of conda_pkg_deps.sh:

# Find which package in the conda package cache requires the given package.

The easiest way I found to create an empty file in Windows 10 like touch in Linux:

>cd . > filename.ext

Conda environment creation & kernel installation

Update: A simpler alternative is to install nb_conda_kernels, which makes accessible all defined environments.

Two commands to run when creating a new env:

# 1. Env creation: always include ipykernel (could be place in .condarc)
conda create --name env310 python=3.10 ipykernel numpy
# 2. Kernel installation: makes env available in jupyter's kernels list
python -m ipykernel install --user --name=env310 --display-name "py310"

Using the Anaconda Prompt on a Windows 10 system:

This is the conda command that creates a new environment with only python installed while excluding
any listed packages under the create_default_packages section of user root folder\.condarc:

(base) [PS1]>conda create -n bare310 --no-default-packages python=3.10

The output (minus a few blank lines):

Collecting package metadata (current_repodata.json): done

Tip: when populating a grid of mpl axes with unknown actual number of datasets, some axes may be empty: clear them AFTER the main loop.

Code source: DETR_panoptic notebook on colab

• In the enumerated loop below, we don't know where i will end (because out["pred_masks"][keep] was not saved into a variable, hence we can't access its length).
• We then use the main loop index into a second one to clear any empty axis.

Example 1 - Simplest implementation: using interact:

=> No need for the function to have a print/display statement => This should also be the behavior of interactive & interactive_output, but it's not

import ipywidgets as ipw


@ipw.interact(x=(20.,250.,5),
          a=(-60.,60.,10),
          b=(-6_000.,6_000,100))
