Description:

mcinstall 0.3.1

A script to quickly make/provision a fresh Miniconda installation from scratch.
The goal of this script is to quickly install a fresh Miniconda across different
operating systems and use it in a CI/CD context, too. It will download a Miniconda
binary based on your operating system, unpack the binary and install it locally.
It was tested on MacOS and Linux ok, has decent Windows support and also aims to
support ARM6 and ARM7 on the Raspberry Pi via Berryconda (sadly no longer maintained).
This script has no external dependencies, but expects to be run with Python 3.5+,
3.5 only because this is likely still the prevalent Python 3 version on Rasbian.
N.B. This project is often updated online which is why its git history might look
strange…

Installation
Very briefly, it’s pip install mcinstall. More details are available in
INSTALL.rst.

Sample Usage
If you run it like this:
mcinstall ~/Downloads/mc3
it will run a command like this on macOS (using some defaults and decent
system introspection) to create a conda base installation:
bash Miniconda3-latest-MacOSX-x86_64.sh -b -f -p ~/Downloads/mc3
This can be activated then with a command like this:
source ~/Downloads/mc3/bin/activate
Windows Example:
On Windows if you execute this command:
mcinstall %USERPROFILE%\downloads\mc3
it will run a command like this:
start /wait "" Miniconda3-latest-Windows-x86_64.exe /InstallationType=JustMe /RegisterPython=0 /S /D=%USERPROFILE%\downloads\mc3
This conda installation can be activated then with a command like this:
%USERPROFILE%\mc3\condabin\activate
Suggested test:
mcinstall --verbose --pip-dependencies jupyter,torch ~/Downloads/torchy
source ~/Downloads/torchy/bin/activate
python -c "import torch; print('ok')"
Suggested test dependencies files:
