Quick-install/provision a fresh Miniconda distribution from scratch.
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Linux ok, has decent Windows support and also aims to support ARM6 and ARM7 on the Raspberry Pi via Berryconda (sadly no longer maintained).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…
Very briefly, it’s pip install mcinstall. More details are available in INSTALL.rst.
If you run it like this:
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:
On Windows if you execute this command:
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:
mcinstall --verbose --pip-dependencies jupyter,torch ~/Downloads/torchy source ~/Downloads/torchy/bin/activate python -c "import torch; print('ok')"
Suggested test dependencies files:
$ more ~/Downloads/reqs.txt asciinema torch torchvision $ more ~/Downloads/env.yml name: test channels: - conda-forge dependencies: - voila
Sample run (replaced home directory with ~ manually):

Example command to pass index-url for pip:
mcinstall --verbose --pip-dependencies pypi_pkg_test --pip-index-url https://test.pypi.org/simple/ ~/Downloads/torchy
Example command to pass extra-index-url for pip:
mcinstall --verbose --pip-dependencies pypi_pkg_test --pip-index-url https://test.pypi.org/simpletest/ --pip-extra-index-url https://test.pypi.org/simple/ ~/Downloads/torchy
Example to pass multiple extra-index-url for pip:
mcinstall --verbose --pip-dependencies pypi_pkg_test --pip-index-url https://test.pypi.org/simpletest/ --pip-extra-index-url https://test.pypi.org/simpletest1/,https://test.pypi.org/simple/ ~/Downloads/torchy
Sample log file (mcinstall.log):
