Conda clean cache

This command will also remove any package that depends on any of the specified packages as wellunless a replacement can be found without that dependency. If you wish to skip this dependency checking and remove just the requested packages, add the '--force' option. Note however that this may result in a broken environment, so use this with caution. Use sys.

This is mainly for use during tests where we test new conda source against old Python versions. Then, the defaults or channels from. You can use 'defaults' to get the default packages for conda. You can also use any name and the. Specify name of repodata on remote server.

Conda will try whatever you specify, but will ultimately fall back to repodata. This is used to employ repodata that is reduced in time scope.

You may pass this flagmore than once. Leftmost entries are tried first, and the fallback torepodata. Forces removal of a package without removing packages that depend on it. Using this option will usually leave your environment in a broken and inconsistent state. Allow conda to perform "insecure" SSL connections and transfers. Identical to '-c local'. Requires --channel. Don't connect to the Internet.

I created this post to have a gather discussion regarding this and what flags we should use in this command!

Remove all writable package caches. This option is not included with the --all flag. The concrete question I mind that we need to answer is more specifically, what flags do we pass to the clean command? The flags detail what to cleanup.

Currently we are using the -tipsy flag, but I fail to find any documentation about this flag, I think it is deprecated in favor of other flags. So, we should probably update this no matter what. Lines 83 to in ae5f7e1. Line 47 in ae5f7e1. Line 68 in ae5f7e1. Woops, so tipsy is simply the list of flags -t -i -p -s -y. You beat me to it. I had planned on making this issue, and had also noticed the -s flag seems deprecated. It's likely that conda clean --all -y is what is wanted, but it's worth doing some testing between that and including -f and see how it goes.

IIRC, jakirkham and I setup some of the initial clean commands a long time ago, probably when we were still on conda 3.

I have few doubts that there are better options today. Maybe putting some lightweight notebook tests in place before making the change would provide some confidence that the changes are not detrimental? Or maybe that's too much work.Metadata is currently fed into conda from JSON files either repodata.

This is good, in that old environments are can easily be recreated. However, it does mean that the index metadata is always growing, and thus conda becomes slower as the number of packages increase. Either packages need to move to archive channels over time, or the server needs to present a reduced view of all available packages. Conda-metachannel is a community project started by Marius van Niekerk that tries to reduce the size of the repodata that gets fed into conda.

Because all of this happens behind the scenes, and conda-metachannel provides a repodata. These ideas will be critical for future developments on repositories offered by Anaconda, Inc. There is no specific development to point to right now aside from conda-metachannel, but these ideas will be part of future development. After downloading metadata, conda loads the JSON file into memory, and creates objects representing each package.

This loading can be costly, but it is cached, so you often are not paying this cost for a given install. Further development will be needed to cache entries on some finer level. For especially large channels, such as conda-forge and bioconda, this step can take a lot of time. For example, consider creating a simple environment without a cached index:.

Adding in conda-forge and bioconda channels dramatically increase the time spent on the creating the index, while using conda metachannel reclaims a lot of the time increase:. The repodata we have at this point probably contains a lot of package data that is not used in the solving stage. The next stage, expressing the package data and constraints as a boolean satisfiability problem, is fairly costly, and filtering out unnecessary packages can save some time.

Conda starts out with only the explicit specs provided by the user. Conda then recurses through dependencies of these explicit specs to build the complete set of packages that might possibly be used in any final solution. Packages that are not involved either explicitly or as a dependency are pruned in this step. This step is why it is beneficial to be as specific as possible in your package specifications.

Simply listing a version for each of your specs may dramatically reduce the packages that are considered after this step. One of the optimizations that was made in conda 4. For example, the anaconda metapackage is made up of all exact constraints version and build string are both specified.

With our anaconda metapackage and zlib example, if some other dependency of anaconda expressed a zlib dependency, that zlib dependency would be ignored for expanding the collection of repodata, unless that zlib dependency also had a version and build string specified. For this reason, we make two careful considerations:. By making this more aggressive, we have decreased the solve time for metapackages, such as anaconda, down to less than 10 seconds in our benchmarks.

There is room for improvement, however, as this style of filtering is still allows versions and builds such as packages built for mismatching python versions into the solver. Filtering these can be expensive, and may be best done at the level of the server providing the repodata. At its heart, Conda relies on something called a SAT solver. Conda thus assigns scores to packages with the same name. These scores account for channel priority, version differences, build number, and timestamp.

These are fed into a clause generator which is customizable by specific SAT implementations in their native format. The solver runs through several stages. At each stage, the clauses are altered or added to to prioritize particular things. People sometimes wonder why Conda returns a particular unintuitive result. Trust us, Conda is not crazy, though the package metadata might be.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

From SMH17 on March 10, That isn't good. Update task should clean older packages after the upgrade, not only download newer versions updating dependencies, deleting manually all older packages is very annoying. For this we have the conda clean --packages command.

Effectively adding a callback to conda clean --packages after a conda update command would be a major change in behavior at this point. If there is more interest in the future by more users, we can continue to discuss.

Cleaning up your Anaconda installations

For now, I'm going to close this feature request as "won't fix" given the above explanation. At the very least, I think that there should be a message displayed to the user after conda updatelike this: "do not forget to apply conda clean -p if you want to clear the package cache". I've just discovered that I had 3 GB of unused packages lying around on my hard disk from previous updates, and I found this quite annoying.
