mamba's Introduction

The Fast Cross-Platform Package Manager

part of mamba-org
Package Manager mamba	Package Server quetz	Package Builder boa

mamba

mamba is a reimplementation of the conda package manager in C++.

parallel downloading of repository data and package files using multi-threading
libsolv for much faster dependency solving, a state of the art library used in the RPM package manager of Red Hat, Fedora and OpenSUSE
core parts of mamba are implemented in C++ for maximum efficiency

At the same time, mamba utilizes the same command line parser, package installation and deinstallation code and transaction verification routines as conda to stay as compatible as possible.

Mamba is part of a bigger ecosystem to make scientific packaging more sustainable. You can read our announcement blog post. The ecosystem also consists of quetz, an open source conda package server and boa, a fast conda package builder.

Installation

Please refer to the mamba and micromamba installation guide in the documentation.

Additional features in Mamba and Micromamba

mamba and micromamba come with features on top of stock conda.

`repoquery`

To efficiently query repositories and query package dependencies you can use mamba repoquery or micromamba repoquery. See the repoquery documentation for details.

Installing lock files

micromamba can be used to install lock files generated by conda-lock without having to install conda-lock. Simply invoke e.g. micromamba create -n my-env -f conda-lock.yml with an environment lockfile named *-lock.yml or *-lock.yaml.

setup-micromamba (setup-miniconda replacement)

setup-micromamba is a replacement for setup-miniconda that uses micromamba. It can significantly reduce your CI setup time by:

Using micromamba, which takes around 1 s to install.
Caching package downloads.
Caching entire conda environments.

micromamba

micromamba is a small, pure-C++ reimplementation of mamba/conda. It strives to be a full replacement for mamba and conda. As such, it doesn't use any conda code (in fact it doesn't require Python at all).

See the documentation on micromamba for details.

Development installation

Please refer to the instructions given by the official documentation.

mamba's Issues

Python version change

I don't have a reproducer where python version was upgraded, but here's an example

conda create -p /home/isuru/miniconda3/envs/py37 python=3.7
conda install opbeat -p /home/isuru/miniconda3/envs/py37 # this errors because opbeat need py<37
mamba install opbeat -p /home/isuru/miniconda3/envs/py37 # Downgrades python to 3.6

Correctly clean package / libsolv cache from time to time

Hello,
first, thank for this package, it's way faster than conda and has saved me a lot of time.

The problem that I've found is that, when you want to install a specific version of a package, let's say
mamba install goatools=0.9.9, it fails to find it so isn't able to install it:

Encountered problems while solving.
Problem: nothing provides requested goatools 0.9.9.*

Notice that I'm not using globs in my search. I've found this with multiple packages and most of the time, maybe all of them, is when i want to install the latest version of a package. Of course the package is available in the conda repositories and when I try to do a mamba install package-name, without specifying the version, sometimes it doesn't install the latest one, so I specify the version, that's the reason I've had this specific problem multiple times. I understand that a package cannot be installed because of the requirements, but in these cases, mamba is saying that the package isn't available.

Creating an environment with geo stack problem with python 3.7

Gave mamba a test drive for installing an environment with the geospatial stack (with mamba-0.0.2 just installed). The following command works:

mamba create -n mamba-geo-test python geopandas cartopy ipython

but, it proposes to create an environment with python 3.6, while I expected it to use the latest python 3.7.

If I try to specify that explicitly:

mamba create -n mamba-geo-test python=3.7.* geopandas cartopy ipython

I get an error (for some reason, it tries to install geopandas-0.1.1.0-py27_0). Full output:

$ mamba create -n mamba-geo-test python=3.7.* geopandas cartopy ipython

An unexpected error has occurred. Conda has prepared the above report.

If submitted, this report will be used by core maintainers to improve
future releases of conda.
Would you like conda to send this report to the core maintainers?

But in any case, it is much faster! (also in failing :))

properly update all dependencies during update

When attempting to update conda-smithy with mamba, it only considers conda-smithy itself for update and not all dependencies of conda-smithy, since the dependency specs are still valid.

mamba update doesn't update to higher build number

Dependency specification unsupported? mamba install blas=*=openblas

This project is awesome! Thank you for working on this! It is a BIG DEAL I think! ❤️ Anyhow, while trying it out I ended up with an error so here comes a report about that error.

It seems to me that mamba cannot manage installing a package where dependencies are specified like here: mamba install blas=*=openblas, this is possible with conda though. When I ran mamba --version I got output about conda 4.6.14. Mamba was installed today.

Use libsolv version instead of mamba version for cache invalidation

Incorrect solution found for ROOT+Python 3

When using mamba to create an environment for root on macOS it chooses an old root build for Python 3. The latest build is chosen for Python 2 and conda always behaves as I expect (eventually... 🐌).

Example

mamba create --name test-env python=2.7 root --dry-run

Chooses: root conda-forge/osx-64::root-6.16.00-py27_blas_openblash6de8b3b_7

mamba create --name test-env python=3.7 root --dry-run

Chooses: root conda-forge/osx-64::root-6.16.00-py37_blas_openblash77af0b3_4

mamba thinks my Python requirement is not fulfilled

I have Python 3.7.6:

Python 3.7.6 (default, Jan  8 2020, 20:23:39) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

but when I want to install a package with mamba install package_name, I get the following error:

Problem: package mamba-0.1.0-py37h1ad3211_2 requires python >=3.7,<3.8.0a0, but

This happens not only with a single package.

Make sure environment creation (with installation) works

@jorisvandenbossche observed the following:

Actually, up to now I only looked at what mamba proposed, but now trying to actually create the environment, I get an error for the example above:

Incorrect python used in entrypoint?

On win64 I installed mamba into a new py37 environment but it looks like the mamba.exe is looking for some random hard-coded python rather that the one in C:\Miniconda3\envs\mamba:

 λ  mamba Fatal error in launcher: Unable to create process using '"c:\bld\mamba_1553594356374\_h_env\python.exe"  "C:\Miniconda3\envs\mamba\Scripts\mamba.exe" '

Note: I don't have a C:\bld folder on my computer

Add only-deps mode

For dev installations where you want only the dependencies of some package.

Support .conda packages

Support is incoming, PR to libsolv is open!

Install pip with python

conda installs pip with python if add_pip_as_python_dependency is not set to False.

[win64] Error then segfault

I'm getting the below error:

Make sure sage installs correctly

@dimpase @isuruf

Trying to install sage python=2.7 with mamba seems to crash. I am investigating locally. Maybe you can help?
What does the crash say?

Breaking change in Conda 4.7.12 for PrefixSetup call

The conda.core.link.PrefixSetup tuple has an additional neutered_specs entry added in conda v4.7.12 here

Commit in conda with change is here: conda/conda@258322f

This breaks mamba here and
here since missing the new required positional argument.

mamba install channel1::pkg doesn't work when channel2::pkg is installed

--strict-channel-priority is not supported

I understand this is a new experimental work, but I was wondering if there are any plans to support the --strict-channel-priority option.

Add use_index_cache behavior

~~index cache only tells conda to use the cache even if it has expired. Therefore the current logic needs to be adjusted.~~

Feature request: add support for conda build

A common case where I run into issues where the mamba conflict resolution is super useful is when trying to diagnose issues with conda build. However, for now I have to translate a conda recipe into a mamba create or mamba install command. It would be great if it would be possible to call mamba build, which would then use mamba any time dependencies have to be installed (and deferring to conda for the rest). Feel free to close if this is not technically possible though!

Add CI

It would be useful to add some CI to run tests.

If we go with Circle CI, we can adapt e.g. this .circleci/config.yml file after removing everything related to python (and rust nightly) from there.

I can make a PR once we agree on which CI service to use.

Installing in non root env messes up -n

conda create -n mamba mamba
conda install mamba
conda create -n py37 python=3.7
mamba install opbeat -n py37

Gives

EnvironmentLocationNotFound: Not a conda environment: /home/isuru/miniconda3/envs/mamba/envs/py37

Update install from source instructions?

After merging PR #44 CMakeLists.txt is not longer present and running cmake throws an error:

CMake Error: The source directory "~/src/mamba/include" does not appear to contain CMakeLists.txt.

Document feature parity (or lack thereof)

Quick question:

is there a quick reference of which commands from conda are or aren't supported? Or a version who's API is the baseline? I'd guess that 4.7.x stuff might not be included yet?

Side note: has there been any discussion yet with the conda peeps about upstreaming this? Or do you first want to prove more exhaustively that it works? I really like the idea, I'm just a bit wary of further and further splintering of the build tool ecosystem.

Remove alpha channel and put on conda-forge

Add USERINSTALLED info to solver

Let the solver know about what packages have historically explicitly been installed by a user.

Remove oversized banner

Some people apparently don't smirk every time they see the awesome banner :)

So we'll get rid of it for something more grown-up-looking.

Version cache, and prune cache from previous versions

conda --quiet argument is not so quiet

conda install -yq produces minimal output. mamba install -yq appears to ignore the 'quiet' argument. It would be nice for mamba to be able to also do quiet installations.

Add support for uninstall

Currently, mamba uninstall whatever doesn't work. Need to find out what to pass to libsolv to do it!

restore string_view polyfill for windows

never works! Throws Cannot use strict priority all the time

I did not manage to install a single package with mamba!
For instance If I say:

mamba install -c conda-forge dvc

I get:


Looking for: ['dvc']

Cannot use strict priority with mamba!

And ALL the packages I tried to install give the same error.
My OS is latest Linux Mint. I use the mamba version 0.1.0 from conda-forge
I also have flexible channel priorities so it is strange why it complains about strict priority

crash on "inconsistant" envs

While running a conda-install on our cluster I come across an "inconsistent env" (I didn't knew it was a thing):

The environment is inconsistent, please check the package plan carefully
The following packages are causing the inconsistency:

  - defaults/linux-64::mkl-service==1.1.2=py37h90e4bf4_5
  - defaults/linux-64::bottleneck==1.2.1=py37h035aef0_1
  - defaults/linux-64::h5py==2.8.0=py37h989c5e5_3
  - defaults/linux-64::bkcharts==0.2=py37_0
  - defaults/linux-64::pytables==3.4.4=py37ha205bf6_0
  - defaults/linux-64::blaze==0.11.3=py37_0
  - defaults/linux-64::anaconda==5.3.1=py37_0

... then conda normal "trying to solve" and maybe install stuff

I thought "Hey, how does mamba handle that ?", so I tried (installing anything does that):

And well it crashed...so just letting you now.

It's a really small corner case, so feel free to close if you do not really care.

Minimamba first run file exists

When running a fresh minimamba, multiple threads might try to create minimamba/pkgs/cache

We need to add a lock I guess.

Make sure that pypy mutex works

It seems that we need to make sure that the pypy mutex exclusion works correctly.

Right now, installing numpy is possible in a pypy env while it's not possible with conda.

Make sure that track_features are deprioritized

Annoyingly, not everything seems to use mutexes in conda at this point ..
libclang has two versions: default and hcc where hcc adds a track feature that should be ranked lower than default in the default mode.

mamba should explicitly depend on conda 4.6+

Running --version fails:

Future of mamba

There has been the word out that you talked with Anaconda about how the mamba changes could be used in conda itself instead of having mamba on-top. What has been the outcome of this? Will we see still a future mamba that patches some speedups on top or is all work going into conda?

Mamba solver is ignored when using `mamba env update`

First, I'd like to say that Mamba is an awesome initiative, I've tried mamba 0.0.7, and it worked very well with mamba install and mamba create, sometimes making the solver 15x faster, with no other apparent differences from the results of conda commands!

conda env update is an important feature, we depend on it to update our environments from environment.yml files, especially because of the --prune flag, that guarantees that the env is an exact match of the spec defined in environment.yml (removing extra packages). I've tried to use mamba env update, but it seems to have no effect in the performance this case (looks like it's using conda solver).

Add support for virtual packages

Currently conda supports __glibc, __osx, __cuda.

Crash when building env

Hi,

I decided to try out mamba, but I get the following when I try to create an env.

(base) $ mamba env create -n osegra -f environment.yml

Decide on the libsolv wrapper

We need to decide how to call libsolv from Rust. As you mentionned @wolfv , the alternatives are,

https://github.com/bkircher/libsolv-rs
https://github.com/ignatenkobrain/libsolv-rs
Write a new wrapper

So far as far as I understand uou went with 1?

That sounds good. Rather than vendoring that code maybe it could be worth forking that repo and adding it as a dependency in Cargo.toml,

solv = { git = "https://github.com/<user>/libsolv-rs", branch = "<some-branch>" }

That would make the separation between the wrapper and this package more clear, while still alowing to make changes to the libsolv-rs fork.

Feature minimization not respected

For eg:

conda create -n pypyp123 python=3.6.9 # gives cpython
mamba create -n pypyp123 python=3.6.9 # gives pypy

mamba broke my conda installation

Mamba command not found (make mamba command available outside base environment)

I installed minimamba and create a minimal voila environment. The issue is that from the base environment I have the mamba command available, but whenever I activate the voila environment mamba is not available anymore...
