.SYNOPSIS
|
||
|
|
Create .venv inside the repo and install mcm-toolkit in editable mode.
|
||
|
|
|
||
|
|
.DESCRIPTION
|
||
|
|
Uses --system-site-packages so the venv reuses the scientific stack already
|
||
|
|
installed in Anaconda base. That makes the whole step OFFLINE: no package is
|
||
|
|
downloaded, yet numpy / scipy / pandas / matplotlib / sklearn / statsmodels /
|
||
|
|
networkx / sympy are all importable.
|
||
|
|
|
||
|
|
The editable install uses --no-deps --no-build-isolation: dependencies are
|
||
|
|
already provided by base, and pip must not go online for a build backend.
|
||
|
|
|
||
|
|
NOTE: this file is intentionally pure ASCII and UTF-8 without BOM.
|
||
|
|
Windows PowerShell 5.1 parses .ps1 as ANSI when there is no BOM, so non-ASCII
|
||
|
|
characters (e.g. Chinese) turn into illegal bytes and cause syntax errors.
|
||
|
|
|
||
|
|
.PARAMETER Python
|
||
|
|
Interpreter used to create the venv. Default: D:\anaconda\python.exe
|
||
|
|
|
||
|
|
.PARAMETER Recreate
|
||
|
|
Delete and recreate .venv if it already exists.
